The Automatic Control Valve, the word is self explanatory. It is a highly engineered Automatic Control Valve

knowledgeably designed to operate off line pressure or if desired, from an independent power source and

pilots. Flow age valves are hydraulically operated, diaphragm actuated for multi-function control of non

corrosive, nonabrasive fluids.

Size Range : 25mm to 500mm

Pressure Rating : Class 150 & 300

MAIN VALVE DESIGN

The main valve is Self Actuating Type, Pilot Operated, Globe/Angle Pattern, Top & Bottom Guided, Glandless,

Hydraulically Operated, and Diaphragm Actuated for multifunction control of less viscous, non corrosive, non

abrasive fluids.

Our wide range of control pilots makes it possible to offer combination models for variety of functions. The main

valves contain only one moving part. This simplicity of design promotes dependability, making the maintenance

easier and extend the life of the valve.

The lower portion of main valve diaphragm assembly is a mechanical check feature, which acts independently

of diaphragm position or pilot control system, and provide immediate check action when flow ceases.

MAIN VALVE CONSTRUCTION

The main valve consist only three major components; Body, Cover and the Top & Bottom Guided Diaphragm

Assembly which is the only moving parts in the main valve making the online maintenance very easy.

With simplicity of design & packless construction, minimum part wear is there which assure trouble free

operation & long life of dependable.

“Flow-Tek” is available in various materials and in full range of sizes with either threaded or flanged ends

MAIN VALVE OPERATING PRINCIPLE

The main valve is normally closed, when pressure is applied to the valve inlet the same pressure is applied to the bonnet also

(upper chamber) the valve remains close. By controlling the pressure in the bonnet the valve can be made fully open or

closed.

AUTOMATIC CONTROL VALVE

[email protected]

FULL OPEN

When pressure in the cover chamber is released to a lower pressure zone the line pressure at the valve inlet opens the valve

allowing full flow.

MODULATING ACTION

FLOW AGE valves are hydraulically operated, by introducing or releasing the liquid from above the diaphragm at controlled rates. A pressure

differential is required, either inlet to outlet or inlet to atmosphere, depending on application.

The control valve holds any intermediate position when operating pressures are equal above and below the diaphragm. The control pilot modulates

the valve to automatically compensate for line pressure changes.

SELECTION

By varying the pilots and piping arrangement this valve is able to perform a diversity functions and Application. Multiple function

performed by a single valve can result in added system protection and lower cost to user The main valve and pilot valve can be

services, without removing from the main pipe line

Valves are sized to provide an appropriate pressure drop for each application. The minimum pressure drop should be 5 psi for inlet to atmosphere and 10 psi from inlet to outlet.

“Flow-Tek” Valves are design for use with clean liquid (water, ATF) application for other media is possible, consult factory.

“Flow-Tek” is a single chamber full port engineered basic valve used in nearly all FLOW AGEs model bearing its description. when the main valve is provided with different combination of pilot & accessories the valve perform a wide range of Automatic Fluid Control making it a specified valve for the Municipal Water Works, Water Distribution System, Fire Protection, Irrigation, Industrial Petroleum & Aviation Fueling System, Marine Theme Park, Decorative Fountain etc. for the system application like Remote Control, Pressure Regulation, Solenoid Operation, Rate of Flow Control, Liquid Level Control, Check Function and many more.

DESCRIPTION :

“FLOWAGE” MAKE Control Valve is a device capable of modulating flow at varying degrees between minimal flow and Full capacity in response to a signal from an external control device. The control valve, often referred to as “the final control element,” is a critical part of any control loop, as it performs the physical Work and is the element that directly affects the process.

PRINCIPLES OF OPERATION :

“FLOW-TEK” Control Valve is comprised of an actuator mounted to a valve. The valve modulates flow through movement of a valve plug in relation to the port(s) located within the valve body. The valve plug is Attached to a valve stem, which, in turn, is connected to the actuator. The actuator, which can be Pneumatically or electrically operated, directs the movement of the stem as dictated by the external Control device.

psi spans Nominal air pressure to Diaphragm : 18 to 35 psi.

:PNEUMATIC / DIAPHRAGM ACTUATED :“Flow-Tek” Pneumatic Actuators are direct acting and utilize an air signal from an external control Device to create a modulating control action. The force of the air signal is received into the Actuator through a top port and distributed across the full area of the actuator's diaphragm. The Diaphragm presses down on the diaphragm plate and spring return assembly, which then moves the valve stem and plug assembly downward to stroke the valve. This actuator will move to a Stem-out position in the event of air signal failure. The choice of valve action (stem-In-To-Close or stem-In-To-Open) will determine its signal failure position.

"Flow-Tek" FT-LPRV- Gas Back Pressure Regulator is the ideal valve for low-pressure gas regulation. The Mark 508 works in conjugation with the in a low-pressure tank blanketing valve system. LPRV can be used to vent gas from the tank to prevent the blanketing pressure from rising to a level that could damage the tank while maintaining a small, constant flow to keep the blanket fresh. During filling, It opens to allow gas to escape as the vapor space in the tank grows smaller. To size properly, find the rate of fill so that a regulator can be chosen based on it's ability to relieve the required amount of gas while sustaining desired blanketing pressure. The Mark 508 will also work well in any other type of low back-pressure gas application.

LIQUID SAFETY VALVE

“Flow-Tek” FT 115 Pressure Relief, Sustaining or Backpressure Control Valve is designed to permit flow when upstream pressure is above the adjustable set point of the control pilot, and throttle toward closed when upstream pressure falls below the adjustable set point.When the valve is installed "off the main line" on the branch of a tee, it serves as a Pressure Relief Control Valve. It is normally closed, and quickly opens when upstream pressure exceeds the pilot setting, relieving excess pressure.When valve installed "in line" connecting two distribution zones, the valve acts as a Pressure Sustaining Control Valve. When pressure in the upstream zone falls below the pilot setting, the valve modulates toward a closed position, sustaining pressure in the upstream zone. When the valve is installed "in line" on the discharge of a pump, it acts as Backpressure Control Valve. When pump discharge

PRS with Control Valve

Pressure reduction for saturated & superheated steam with pneumatic control valve with PID control, which ensures high accuracy and fast recovery from disturbance in downstream pressure.

“Flow-Tek” We offer Pilot Operated Pressure reducing Station for Liquid Service. It is more efficient and economical to produce steam at high pressures ready for delivery through the distribution system. This may mean that the pressure needs to be reduced prior to the point of use or for different parts of the system. A reliable method of providing pressure reduction is to use a pilot operated pressure reducing valve station.

DESUPER HEATER

"Flow-Tek" Desuperheater leading suppliers of Steam Desuperheaters. We specialize in designing and manufacturing such equipment for power, process and co-generation plants.

STEAM DESUPERHEATERING The most practical way of reducing the superheat value of steam is by the direct addition of water. To achieve temperature stability of the conditioned steam and prevent thermal shock in downstream pipes, cooling water must be atomized. It is also necessary to have a correct mix of superheated steam and cooling water.

The potential to reduce the degree of outlet superheat is limited by the capability of control system. Almost all desuperheaters are used to reduce the steam (or gas) temperature as close to saturation as possible.

Most desuperheater models (types) are actually capable of achieving saturation or close to the saturation. The cavities that these units must be controlled precisely to prevent flooding of the whole system. The limitation of the control system is its sensitivity range. Consider a system with a controlled outlet temperature set at 1 °C above the saturation, where the controls are designed to maintain +/- 1 Deg.C.

The cooling water injection into the steam will continue till the temperature falls to saturation.. Then only the controls will reduce the cooling water injection. Due to the delays inherent in the control system (specifically introduction of derivative band) which is not in scope of desuperheater manufacturer, cooling water will continue to flow at the design rate for a short time. In that small amount of time, the saturated steam will be allowed to condense. Condensing vapor creates a vacuum, which sucks in more vapor, which too continues to condense. This results in loss of control, downstream equipment may be damaged & the downstream processes may be severely affected. Due to these reasons, we have opted to not guarantee DE superheating lower than 4 - 5 °C above the saturation. The downstream processes do not suffer much from such small amount of superheat.
