Core feature
Flange connection:
Both ends of the valve body with standard flanges (such as GB, ANSI, DIN, etc.), through the bolt to the pipe flange docking, sealing gasket (rubber, metal wrap gasket) to ensure the tightness of the interface.
Advantages: Suitable for high pressure (PN16-PN40), large caliber (DN50-DN2000) scenarios, anti-vibration, anti-loosening, easy to disassemble and maintain.
Pneumatic actuator:
Equipped with single action (spring return) or double action (two-way air control) cylinder, the output torque is large, the drive valve plate 0°~90° rotation.
Optional intelligent positionists (such as IP67 protection level), support 4-20mA signal or bus communication (PROFIBUS, HART), to achieve accurate opening adjustment.
Seal design:
Soft seal: EPDM, NBR rubber seat, suitable for room temperature (-20~120ºC) and non-corrosive media (water, air, oil), leakage class VI (zero leakage).
Hard seal: stainless steel + graphite surfacing or metal to metal seal, high temperature (≤425ºC), high pressure and granular media (such as steam, dust).
Key parameters of selection
Flange standard: According to the pipe design selection (such as GB/T 9119, ANSI B16.5).
Diameter and pressure: DN50~DN2000, pressure class PN10~PN40 (or Class150~Class300).
Media matching:
Corrosive medium: body material selection CF8M (316 stainless steel), seal selection PTFE.
High temperature steam: metal hard seal (e.g. Stellite 6 alloy), body material WCB.
Pneumatic accessories: ATEX certified actuator for explosion-proof environment; Adjustable type requires 0.5% accuracy positioner.
