Structural Features

1. This series of valves with removable structure. Valve cavity parts (including the valve seat, the valve core, throttle ring, shroud, etc.) can be removed from the valve cavity inspection, repair or replacement. The body does not need to be cut from the pipe and can be used multiple times. Economic and reasonable.

2. Spool with balanced structure, unbalanced force is very small, high precision valve action.

3. The valve opening of 40% or less, the flow from multi-level shunt pack integrated throttle control, with multi-stage buck and anti-cavitation function.

4. Flow sleeve is not only the spool for straight movement positioning sleeve, but also has a comb, decompression, muffler role, the special processing and heat treatment, HRC ≥ 45, anti-cavitation, erosion-resistant.

5 valve plug and seat sealing surface surfacing carbide, long service life.

6. Valve Body Installation The working surface of the valve seat (the sealing surface of the valve body in contact with the valve seat) is welded with chrome-nickel stainless steel to ensure the sealing performance of the valve body.

Postscript

If conditions permit, the flow control requirements are not strict, only for cut-off when the throttle, then use the electric device to drive as well. In this way, the valve closing the end of adjustable torque, to be closed too strict, open to play, can throttle; valve also no virtual customs phenomenon, longer service life.
