Main Materials

Body: ASTM A53 or equivalent to 20# steelStem: AISI 304 or equivalentBall: AISI 304Stem Seal: VITONStem / Bushing: 304 + PTFESeat Seal: 25% C + PTFE

Applications

Suitable for heating / cooling systems, heat exchangers and various pipelines;urban gas pipelines, large-scale heating equipment pipelines, various fluid services in steel mills,gas and heat supply systems, and fuel supply pipelines.

Structural Features

Filters out impurities and large particles in the medium.Foreign particles are trapped at the bottom of the strainer, while the medium flows through normally,without additional heat loss, internal pressure buildup on the valve, or reduction of service life.

During valve maintenance, the cavity pressure can be relieved via the pressure relief valve.The drain port can then be opened for cleaning and servicing of the strainer, ensuring safe and reliable operation.

Operation Types

Various types of valve actuators are available:manual, pneumatic, electric, hydraulic, gas-hydraulic, etc.Specific models are selected based on the operating torque of the valve.
