CV3000-DHCB Electric Cage Regulative Valve

CV3000-DHCB Electric Cage Regulative Valve

Structural features and applied range

CV3000-KHCB electric cage regulator is pressure balanced regulator, trims use socket oriented guide valve core, it mainly uses fluid pressure to realize valve core rapid movement, operating force is small. In addition, sealing type uses single seat sealing, high precision flow characteristic curve, in accordance with IEC534-1 standard. Regulator dynamic stability is good, noise is low, and air defense, it is suitable for controling kinds of temperature high pressure difference flow. Equipped with electric actuators, its structure is compact, and output is large.
The product conforms to the GB/T4213-92.
