Features

Low Leakage: The ball and seat form a surface contact seal, achieving zero leakage in the closed state, passing the EN 12266-1 Grade A sealing test.

Wide Compatibility: The valve body features an ISO 5211 standard mounting platform on top, allowing direct actuator installation without additional brackets or transition connections.

Extended Operating Conditions: Valve body materials include carbon steel and stainless steel (such as WCB, CF8, CF8M, A105, F304, F316), with optional soft or metal seal structures, enabling the same design to cover low-temperature to high-temperature and corrosive media conditions.

Applications

Oil and Gas: Used for media shut-off in pipelines, enabling fluid flow control during opening and closing to meet pipeline segment isolation and maintenance needs.

Chemical Industry: Used in pipelines carrying various corrosive or reactive media, enabling process switching and equipment isolation through valve opening and closing.

Power Industry: Used in steam or auxiliary system pipelines to achieve media flow control and isolation during system maintenance.

General Industrial Systems: Used in water, air, and general industrial fluid pipelines to achieve opening and closing control and operational switching between upstream and downstream equipment.

FAQ

Q: How to select the sealing type based on operating conditions?

A: For clean media at normal temperature, a soft seal structure is preferred to meet zero leakage requirements; for high-temperature or particulate media, a metal seal should be used to prevent the soft seal material from failing under temperature or erosion conditions.

Q: What precautions should be taken when installing a wafer-type valve?

A: During installation, ensure the parallelism and coaxiality of the flanges on both sides to avoid valve body displacement due to uneven clamping; at the same time, tighten the bolts evenly according to specifications to ensure consistent stress on the sealing surface.

Q: How to reduce the frequency of malfunctions and maintenance in daily use?

A: Avoid keeping the valve in a semi-open state for extended periods to reduce local erosion of the ball and seat; and regularly open and close the valve and check the wear of the sealing surface according to the media conditions to maintain sealing performance.
