I. Performance:

Ball valves produced in Gazomet are made of forged steel. Fully welded body provides safe operation and absolute external tightness.
In valves produced in our company we use the following technical solutions that provide dependability during operation:
• triple stem sealing,
• stem protection against exhaust,
• sealings of SOFT, PMSS type,
• system of improving leak-tightness,
• antistatic system,
• FIRE SAFE protection,
• possibility of equipping with various columns,
• tested and dependable sealing systems,
• DBB (Double Block & Bleed) system that enables to degas a space between a body and a ball.

Dimensions: DN6 – DN700
Pressure classes: PN6 – PN420 (up to ANSI 2500)

Design and performance standards:
• PN-EN 14141
• PED Directive 2014/68/UE
• ISO14313
• NACE MR0175

II. Application:
Ball valves with fully welded body are produced for wide range of pressure. They are designed in a way that enables maintenance-free operation in difficult conditions of operation.
A. Ball valves produced by GAZOMET are destined mainly for gas and oil industry.
They are used in:
• distribution,
• gas transmission,
• process and technological lines,
• gas mines,
• underground gas storages,
• gas distributive and measuring junctions,
• regulating , measuring, regulating-measuring gas stations.
B. Ball valves produced by GAZOMET are also used in other industry fields, they are produced for, i.a.:
• aggressive media,
• petroleum-derived fuel.



      Fire safe test
Production programme of ball valves comprises:
diameters from DN6 to DN700 and pressure range from PN6 to PN420.

Standard performances of ball valves can be used in temperature range from -30°C do +60°C.

III.                    Tests
Ball valve tests are conducted according to Framework Technical Specifications formulated on the basis of effective standards and regulations.

IV.                  Documents received with delivery:
Ball valves are delivered with the following documents:
·         Certificate of Technical Acceptance 3.1 acc. to PN-EN 10204,
·         Declaration of Conformity acc. to Directive 97/23/WE (CE mark),
·         Assembly and Operation Instruction,
·         Warranty.

V.                Actuators
All ball valves, depending on a torque that is needed for opening, are equipped with lever or worm gear. Optionally, ball valves can be equipped with electric, pneumatic or electric-pneumatic actuators.

VI.                Columns for ball valves
Underground ball valves are equipped with columns which enable steering a ball valves that is installed under the ground.
GAZOMET offers two types of extensions:
1.       Rigid columns (Klo, KL)
Height of columns of this type is stable measured from the axis of a ball valve up to the top of a stem or the axis of a handle of an actuator.
2.       Telescopic columns (KT)
This type of column has the possibility of height regulation which can be fitted to existing housing conditions (400 mm).
An actuator cannot be installed on the telescopic extension.
