GOST332529 Trunnion Mounted Ball Valve PN16 DN150 SS904L

Data Sheet

Symmetry port，good for medium flow. Sophisticated process,precision production. Strong toughness, high pressure resistance, and high pressure and crack resistance of thickness.

ZJCLV valves are designed both standard thick on body and flanges, so reliable for exposure shell performance and pressure resistance as 1.5times than the standard pressure so for long time usage.

The valve weight is more than standard.  Note: many cheaper valves from other companies always reduce the body thickness to save cost. So it is important to check not only the flange thickness but also the valve weight too simply to difference the good and bad valves.

This valve is designed with blow-out stem,  as most popularly used valve type in ball valves. It is convenient and durable as due to the design of the valve stem, this structure is beneficial to the lubrication of the valve stem, most popularly used in application. More, the stem material is stainless steel ss316, which is nitridizing treatment so to strengthen the hardness of the stem.

This ball valves PN16 DN150 is designed with sealant injection device on stem and seat. When the seat ring or stem O ring is damaged due to accident, the corresponding sealant can be injected by the sealant injection device to avoid medium leakage on seat ring and stem. If necessary, the auxiliary sealing system can be used for washing and lubricating the seat to maintain its cleanliness.

Anti-static structure and adopts the static electricity discharge device to directly form a static channel between the ball and body or form a static channel between the ball and body through the stem, so as to discharge the static electricity produced due to friction during the opening and closing of ball and seat through the pipeline，avoiding fire or explosion that may be caused by static spark and ensuring system safety.

This trunnion pipeline ball valve adopts the trunnion ball structure, so as to achieve lower torque under operating pressure.

Trunnion mounted ball valve is a new generation of high performance ball valve. It is labor-saving operation：ball is supported by upper and lower stems to reduce friction and eliminate the formation of the ball and the sealing seat driven by the inlet pressure to prevent excessive torque due to huge sealing load.
