MSA, a.s. manufactures three-piece ball valves with trunnion
mounted ball. Individual body pieces are connected by bolts
in case of K 83 TB design, or they are welded together in case
of K 83 TW design. All ball valves can be supplied also with
reduced bore.
Ball valves are used in service conditions which require complete opening or closing of medium flow. Most often used service medium is gas, oil and water.

Design Details
BodyBody is made of three forgings, where the individual parts are bolted or welded together. Body
dimensions are chosen to meet not only strength and rigidity requirements of corresponding stand-
ards, but also to be able to transfer external forces and torques from pipeline.
Seat (Pict. No. 1)Necessary thrust of a seat to a ball is at low pressure provided by spiral springs. At high pressure the
thrust of a seat to a ball is increased by pressure of service medium in pipeline. For gaseous media
it is recommended to use PMSS seat (Primary Metal Secondary Soft). Secondary sealing ring is of
delta shape, made of HNBR (Therban or Elast-“O“-lion) or Viton. For liquid media it is recommended
to use seat with hard seal ring inserted in to metal seat ring. Teflon and its modifications (Devlon,
Nylon, PEEK etc.) are used for hard seal insertion. Sealing paste, which can be injected between seat
and ball, can be used as tertiary sealing (Pict. No. 2). Seats with soft sealing rings are automatically
supplied as DPE design (Pict. No. 4). DPE design means, that if upstream seat is damaged, function
of a ball valve is still secured by a downstream seat.
Stem (Pict. No. 3)Stem is of anti blow-out design so it cannot be ejected out of a body due to improper handling. It is
primary and secondary sealed by two independent rings. It can be tertiary sealed by sealing paste.
Secondary ring can be replaced even under full pressure load with the ball either open or closed.
Antistatic DesignAll internal metal components are conductively connected with ball valve body.

Double Block and Bleed (DBB) (Pict. No. 5)All ball valves are supplied with DBB feature, which means that it is possible to bleed the body cavity
in fully closed or fully opened position.
LubricationForces arising due to pressure acting on a ball are caught by self-lubricating bearings with low fric-
tion coefficient. Thus the ball valves have low torque and do not require any maintenance.
External LeakageTheoretical areas of external leakage are body-bonnet joints and trunnion. These parts are therefore
designed to meet requirements for emission-free valves.
Position Adjustment (Pict. No. 6)Every ball valve, which is supplied without actuator (bare stem), is equipped with a special device,
by which it is very easy to adjust ball position even in case when it is not possible to have a look
into valve bore. From this reason it is possible to perform installation or removal of actuators on ball
valves also after their installation into pipeline. For other ball valves this device must be specified
in an order.
Fire-Safe DesignMSA ball valves are fire-tested for the whole manufacture range according to API 607, API 6FA a BS
6755, part 2 standards. Fire-safe certificate was issued by an independent international organiza-
tion.

Accessories
Stem extension (Pict. No. 7)Stem extension is available based on customer’s request, namely for underground valves. Length of
stem extension is not limited, however it must be always specified (see picture).
Accessories (Pict. No. 8)MSA furnishes ball valves with further accessories depending on customer’s requirements, such as
drain, vent, grease fittings, power supply to actuators, pressure relief valves etc. All these acces-
sories are made of stainless steel pipes. Sealant injection lines are terminated by two independent
grease fittings. Drain and vent pipes, actuator supplies are terminated by ball valves.
Pressure reduction in ball valve bodyIn case that service conditions enable increase of pressure in body cavity higher than nominal
pressure, ball valve must be ordered with a device for pressure reduction. This is enabled either by
seat modification or by a relief outside the ball valve. When relieving pressure through seat, DPE
function is canceled.

Pups (Pict. No. 9)MSA ball valves with butt-weld ends do not require any pup pieces if operating and installation
instructions are observed. However, if pup pieces are required, MSA supplies pup pieces in two possible
options:
Option A: Pup piece is a forging, which is welded to basic material before final machining. Ball valve is
assembled together with the pup piece. This option is used for pup pieces up to 200 mm.
Option B: Pup piece is a part of pipe of the same grade and dimensions as pipeline. Ball valve is manu-
factured and tested with standard dimensions and then pup piece is welded and checked.
Pup piece length is not limited for this option, except for transport reasons. However, if pipe
of non-standard grade or sizes is used, it is recommended that the customer supplies the
pup material.
ActuatorsValves are supplied either with or without actuators. Actuators can be of manual, electric, pneumatic-
hydraulic, electric-hydraulic, pneumatic or hydraulic type. MSA cooperates with all leading actuator
manufacturers.

We supply ball valve accessories as per customer’s requirements or based on service conditions.

Pressure testsAll pressure tests are performed in accordance with API 598, API 6D and DIN 3230. MSA
also performs special tests according to API 6D as a standard, such as low pressure air test,
DBB test and DPE test. Acceptance criteria is zero leakage for all the tests.
MSA also performs test by full operating pressure as a standard. This is the only test which
can reveal possible leakage in the body-cover joint, stem, accessories, grease fittings etc.
Special testsMSA performs many special tests, by which we verify properties of our ball valves. All
tests are witnessed by independent test institutes. The following tests were performed
on MSA ball valves:
Fire test – according to API 6FA, API 607 and BS 6755, part 2,
for Class 150, 300, 600 and 900
Tightness and functional tests – at temperature –60 °C to +200 °C
Cycle test – test for 5000 cycles (open-close) at full differential pressure with gas con-
taining large mechanical impurities
Hydrodynamics and aerodynamics test – verification of hydropneumatic and
aerodynamic properties is done with simultaneous measurement of torque value in
dependence on angle of ball opening
Non-destructive testsMSA performs non-destructive tests in its own test rooms and equipment. Non-destructive
tests include RT, MT, UT or DP tests. Personnel performing these test is highly qualified and
certified according to EN 473 or SNT-TC-1A.
Functional testAll ball valves are functionally tested together with actuator. Torque value is verified
during this test as well.
CertificationMSA quality system is based on strict observance of EN ISO 9001:2000 and API Spec Q1 (Specification 6D – number 0239).
Inspection of manufacturing process has critical influence on quality.Whole manufacturing process is thoroughly monitored and includes the following tests and inspections: receiving inspection of all raw materials and sub-supplies, in-process inspection during manufacture of individual parts, assembly tests, pressure tests, functional tests, non-destructive tests, final inspection of finished products.

Application of Standards
Research and Development
MSA specialists deal with research and development activities and
before creation of a new product they verify its properties, such as:
• fitness of materials used
• design strength and rigidity (FEM method)
• design functionality with stress on tightness and controllability
• hydraulic and aerodynamic properties etc.
New product is tested both at MSA testing rooms, as well as in real service condi-
tions. Product properties are regularly monitored during its whole service life and
findings are applied for development and manufacture of new products.
