Brief Introduction of GOST 5762 Russia standard cast steel metal hard seal rising stem flange gate valve:

Cast steel rising stem flange gate valve is the replacement of the traditional cast iron gate valve, which has compact structure, reasonable design, good valve rigidity, smooth channel and small flow resistance coefficient; the sealing surface of GOST cast steel gate valve is made of stainless steel and hard alloy, and its service life is long; the GOST cast steel gate valve adopts the flexible graphite packing, which has reliable sealing performance, and is labor saving and flexible to operate; GOST cast steel gate valve is widely used in petrochemical, metallurgy,water treatment, thermal power plants and other oil and steam pipelines as opening and closing devices for connecting or cutting off the medium in the pipeline;

Advantages of GOST cast steel gate valve:

1. GOST cast steel gate valve has compact structure, reasonable design, good valve rigidity, smooth channel and small flow resistance coefficient, is easy and convenient for maintenance;

2. GOST cast steel gate valve adopts the flexible graphite packing, which has reliable sealing performance, and is labor saving and flexible to operate;

3. GOST cast steel gate valve can be operated through manual hand wheel, electric actuator,pneumatic actuator, worm gear box;

Applications of GOST cast steel gate valve:

GOST cast steel gate valve is widely used in petrochemical, metallurgy, water treatment, thermal power plants and other oil and steam pipelines as opening and closing devices for connecting or cutting off the medium in the pipeline;
