Product Introduction
Service Promise
Ordering Process

ZJHM pneumatic sleeve control valve is small, light, high performance, large capacity, is in line with the IEC standards of a new generation of universal control valve products. It is suitable for the production process system of general fluid medium and technological conditions.

The product consists of a new pneumatic multi spring actuator and a low flow resistance sleeve valve. The characteristics are as follows:

1. Adopting balanced core, small unbalanced force, large allowable differential pressure and stable operation.

2. Large spool guiding surface can improve oscillation caused by eddy current and impact and reduce damage.

3, noise reduction is about 10bd compared with ordinary one or two seat control valves.

4, simple structure, easy installation and maintenance.
