Features

Bidirectional Hard Seal

Both the valve body sealing surface and the gate sealing surface utilize hard seal welding, resulting in superior sealing performance and durability compared to single-sided welding.

Flexible Operation

Optional handwheel, gearbox, and pneumatic actuator options are available to suit different operational efficiencies and automation requirements.

Stainless Steel Valve Body

The flanged cryogenic gate valve is made of A351 CF8M material, possessing excellent corrosion resistance and low-temperature toughness.
