I. General of Valve1. History of Valves

Principle components of piping which transfers the fluid are pipe, valves &

fittings etc.

The early stage of civilization : use the clay, stone, wood or leather as the

material of pipeThe Bronze Age : use easy material as like lead or copper16th century : Wilkinson in UK invented the machinery manu-

factured the pipe in bulk17th century : Dennis Papin invested the safety valve for over

pressure18th century : James Watt applied the modern type valves to

his steam locomotive (Plug Cock Valve, Butterfly Valve)19th century : 1839 – early stage Gate Valve (invented by

James Nasmyth) 1875 – Plug Valve (manufactured by Dowrance

Valve) 1886 – Gate Valve (manufactured by Hopkinson

Valve)20th century : 1929 – Diaphragm 1930 – improve the Ball Type Plug Valve to mod-

ern Ball Valve 1945 – Automatic Control Valve

2. Basic of Valves

2.1 Four Functions of Valves

1) Shut-Off 2) Flow Control 3) Direction Control 4) Overpressure Protection

2.2 Valve Type (Function)

1) Shut-off Valves * Linear Motion

Globe Valve, Gate Valve, Diaphragm Valve * Rotary Motion

Butterfly Valve, Ball Valve, Plug Valve2) Flow Control Valves

* Linear Motion Globe Valve, Needle Valve

* Rotary Motion Butterfly Valve

3) Directional Control Valves * In Line Type

Non Return Valve * Switching Type

3-way, 4-way Valve, Angle Valve4) Overpressure Protection Valves

* Manual Type Breather Valve

* Automatic Type Relief Valve

Globe Valve *Throttling, high pressure valve

* Minimize the loss of seat and disc * Less operating time rather than Gate valves * It is comfortable to change the disc & seat * Flow path: S pattern * Pressure loss: great

Note: Use for flow control, provided that the pressure loss is not great con-cern.

Gate Valve * No use for throttling (disc vibration, seat wear)

* Small length between the face to face. * Big size, but small weight * High space is needed because of valve lift. * Flow path: straight pattern * Pressure loss: small

Note: Use for on-off , not for flow control

2.3 Features of Valves

Butterfly Valve * Use for Throttling

* Limit for high pressure and tem-perature * Flow path: straight pattern * Pressure loss: small

Note: Use the flow control valve be-cause of the good flow capacity

Ball Valve * No use for throttling (turbulent, vibra-tion, noise, water hammer)

* Limit use for high pressure & tem-perature * Multi Port (L port: Diverting, T Port: Diverting & Mixing) * Quick operation (Quarter Turn) * Automatic valve is available (actua-tor) * Flow path: straight pattern * Pressure loss: small Note: Use for on-off, not for flow control

Check Valve* If the system pressure is constant, open the valve.* If the system pressure is reduced, close the valve

Note: Use for safety valve that pre-vents the return of flow

Relief Valve* If the system pressure is constant, close the valve.

* If the system pressure is reduced, open the valve

Note: Use for safety valve that pre-vents the overpressure of system.

2.5 Structure of Sealing

- Body to BonnetBecause Body and Bonnet are the principle structure of valve and internal pressure part, the connection of two components shall be perfect and have high reliability.

- Trim (Disc or Ball, Seat)Trim as the important part component for valve performance is di-rectly contacted with the system fluid, and have the strong charac-teristics for vibration, torsion, erosion and corrosion except the on-off or flow control function.

- Stem SealStem seal is the part component that maintains the airtight be-tween the bonnet and stem. The stem sealing leakage is the critical factor that reduces the reliability of the valve. Two methods of stem sealing are packing sealing and packless sealing

2.6 End Connections

The methods for connecting the valve to piping are various. In general, there are tubing type, threaded type,

welded type and flanged type

- Tubing Type (Hy-Lok, Bite Type)It is possible up to 2”(50mm), but economical below 1”(25mm). It

is easy forinstallation and suitable for high temperature, temperature

change and vibration service.

- Threaded Type (ASME/ANSI B 16.11)It is possible up to 2”(50mm) and the standard below 1”(25mm).

It is low price and easy for installation but not suitable for high temperature,

temperature change and vibration service due to loosening of connection

part.

- Welded Type (ASME/ANSI B16.8, B16.11)Use the socket weld (B16.11) up to 2”, butt weld(B16.9) above

2”. It is low price but difficult for installation and maintenance. It is

suitable for high temperature, temperature change and vibration service.

- Flanged Type Most piping valves are flanged type and widely used because of

easy maintenance. Normally it is FF (Flat Face), RF (Raised Face), RTJ

(Ring Type Joint). There are various flange specifications in accordance with

ASME/ANSI

* FF (Flat Face) Flange It is widely used for the cast iron valves, below ASME/ANSI

Class 150. Because the casting RF flange has a tendency to brittle.

* RF (Raised Face) Flange It is widely used for the cast steel valves, above ASME/ANSI

Class 150.

* RTJ (Ring Type Joint) Flange It is widely used for the high pressure and high temperature

service, above ASME/ANSI Class 300.

3. Material of Valves• Materials of valves are divided into body, bonnet, trim and

packing materials.• When choose the materials of valves, the followings shall be

considered; the corrosion resistance, wear resistance for pressure, economical efficiency for high or low temperature and safety for temperature.

• • - Materials of Body & Bonnet• The materials for Body and Bonnet which are the pressure

containing part, are same and divided into forged steel, rolled steel and cast steel. (Reference: Table 1. List of mate-rial specification – ASME/ANSI B 16.34)

• ASME/ANSI standard list the pressure-temperature ratings for each class and material group. Intermediate classes are determined by linear interpolation from standard classes.

• - Material of Trim• Because trim material is connecting with fluid and actually

operation part, use the materials of corrosion resistance and wear resistance. If the fluid contains the floating solids and the differential pressure and fluid temperature are high, trim shall be hardened.

• Because of the galling, use the different materials or if same material, it shall be heat- treated for getting the hardness difference.

- Ball Valve Seat• Ball valve seat is very important because it directly impact

on life cycle and sealing performance of valves. Seat mate-rials are mostly elastomer, having chemical resistance, high temperature resistance and good wear resistance. Espe-cially, Teflon seat for ball valve is genuine Teflon and carbon mixed Reinforced Teflon.

• - Materials of Packing• Packing shall have the constant force for maintaining the

sealing with fluid pressure and stem’s continuously opera-tion.

• It shall be not deformed through fluid temperature and other effects.

• The materials for packing are Teflon, Grafoil.

* Teflon• It is non-active in chemicals and has the self-lubrication. It

is used for all fluids at the operating temperature from -80C to 200C and with spring because of maintaining the constant force and sealing property.

* Grafoil

• It is non-active in chemicals and low friction coefficient. Op-erating temperature is from -240C to 3,000C and so it is suitable for the cryogenic and ultra-high temperature ser-vice. But the operating torque of stem is high due to high density of grafoil.

II. Selection of Valve It is very difficult to select the valve in accordance with user’s re-

quirements. The principle design of Hy-Pro valve is done accord-ing to the international standard and this is very important de-sign factor to satisfy the performance and reliability of valves.

- Fluid Liquid & Gas Flammable, toxic, corrosive and ultra-clean flow media Steam of high pressure and temperature Select very carefully the materials of valve (Refer to the Fluid Compatibility Table)

- Pressure Pressure Ratings: ASME/ANSI Class Pressure ratings of valves are closely related with the temperature. (Refer to the ASME/ANSI B 16.34 Pressure-Temperature Ratings) Pressure Drop is very important factor to select the valve. Potential Pressure Drop is known from the Cv. High pressure drop increases the operating cost of system. High pressure drop decreases the life cycle of the valve. Flow path: straight pattern has less pressure drop than the S pat-

tern.

- Temperature Higher temperature, less pressure rating Temperature is the most important factor to select the packing

and trim materials. (Refer to the Seal Material Application and Properties)

- Flow The purpose of flow control is the factor to selecting the type

and size of valve. On-Off Type: Gate Valve, Ball Valve, Plug Valve Throttling Type: Globe Valve, Needle Valve, Butterfly Valve Direction Control Type: Non Return Valve (Check Valve) Valve Size (Cv): Valve Capacity

- Example Valve Type: Ball Valve Material: Stainless Steel 316 End connection size: 1/2” NPT (Female) Application Fluid Pressure Rating: ASME/ANSI Class 2500# (6000 paisg) Pressure-max. Temperature ratings: 5200 psig Flow Coefficient: 10.0

III. Basic Design of Hy-Lok Valves

* Process Valve Standard ASME/ANSI B 16.34 is widely used in process valve Specify the material, pressure ratings, design and wall thick-

ness etc.

* Instrument Valve Standards ASME/ANSI B16.34 do not cover the instrument valves MSS SP-99 specify the material, design, pressure ratings, test

and end connections etc. These both standards are used for the design of Hy-Pro In-

strument Valves.

- Materials Select the material for the body and bonnet(pressure retain-

ing parts) in accordance with the ASME Section VII BPV Code, ASME/ANSI B31 Piping Code B16.34 and MSS SP-99. Purchaser in accordance with the ASTM standard.

Additional quality and performance requirements are in ac-cordance with manufacturer standards or client’s specifica-tions.

* Design Calculating for Wall Thickness and Cold Working Pressure

(CWP) is in accordance with allowable stress and formula of ASME/ANSI B31 Piping Code & ASME Section VII BPV Code.

* Test• Valve design and pressure rating meet the requirements of

the specified burst and performance.

• Pressure test confirms the weak points and external leakage of valves.

• Shell test of Hy-Pro Instrument Valves are done in accordance with ASME/ANSI B 16.34 pressure ratings. Apply 1.5 times of pressure ratings of ASME/ANSI B16.34 and duration of test is 15 seconds.
