Product Type: HCBE

Features:

Details

One, HCBE pneumatic valve cage Overview: is the introduction of technology-based, are CV3000- is pressure balanced valve, parts using a sleeve-oriented pilot spool valve, it is mainly realized by the pressure of the fluid valve fast action, operating force.

In addition, single-seat seal type seal, high precision flow characteristic curve, in line with IEC534-1 standards. Valve dynamic stability, low noise, cavitation, suitable for a variety of temperature control of the fluid pressure differential.

Equipped with multi-spring diaphragm actuator or electric actuator, compact structure, large output force. This product complies with GB / T4213-2008. The main advantage of the fluid pressure to achieve rapid action valve, operating force. HCBE cage valve seat seal single seal, high accuracy flow characteristic curve.
