CV3000-DHSC Explosion-proof Electric Cage Single-seat Regulator

CV3000-DHSC Explosion-proof Electric Cage Single-seat Regulator

Structural features and applied range

CV3000-DHSC explosion-proof electric cage single-seat regulator is suitable for braising cavitation occasion that high pressure differential is easy to generate, is a high-performance single seat regulator, strong protection sleeve protects valve from braising and cavitation damage. The structure is compact, with “S” streamline channel, reducing the pressure drop, large flow, wide adjustable scope. Valve core guide area is large, anti-vibration is good. The leakage of regulator conforms to ANSI B16.104 standard. Regulator euipped with multi-spring diaphragm actuator, its structure is compact, and output is large.
The product conforms to the GB/T4213-92, VDS4006-92 standard.
