Compact pneumatic sleeve regulating valve
ZJHM precision small pneumatic sleeve regulating valve
Product details
The ZJHM precision pneumatic thin film sleeve regulating valve consists of a pneumatic thin film multi spring actuator and a precision small sleeve valve.
The main features are as follows:
1. Adopting a balanced valve core, it allows for a large pressure difference and stable operation under unbalanced forces.
2. The large guiding surface of the valve core can improve the oscillation caused by eddy currents and impacts.
3. Reduce noise by about 10dB compared to ordinary single or double seat regulating valves.
4. The structure is simple and easy to assemble, disassemble, and maintain.

Note: 1. Basis for determining allowable pressure difference:) Standard spring 20-100KPa; 2) Valve closed P2=0; 3) The flow direction is from bottom to top; 2. For the bellows sealed regulating valve, the maximum allowable pressure difference is 1.0 MPa. If the value in the table is less than 1.0 MPa, it remains unchanged. If it is greater than 1.0 MPa, it is taken as 1.0 MPa.
