Product Description
Pneumatic Diaphragm Sleeve Control Valve (ZJHM)
Summary:ZJHM pneumatic diaphragm sleeve control valve is a kind of high performance, large capacity control valve products. It adopts sleeve guide structure, and has large guide area and good stability, which can be quickly replaced online valve internal parts. The maintenance efficiency is higher, and it can saves manpower and time. Pneumatic diaphragm sleeve control valve is widely used for its good stability and simple maintenance. Pressure flat guard spool can eliminate most of the static uneven force on the disc, and has a certain blocking effect, which can reduce the vibration caused by fluid flow. It is especially suitable for occasion about leakage requirements is not high, the valve pressure difference before and after the occasion is large.

Advantages:
1. Adopt balanced spool, unbalanced force, large pressure difference and stable operation.
2. Large spool guiding surface can improve the oscillation caused by eddy current and impact and reduce damage.
3. The noise is about 10dB lower than that of ordinary single or double blocks.
4. Simple structure, easy installation and maintenance.
Principle:
Pneumatic diaphragm sleeve control valve use electrical and pneumatic valve positioner, powered by electrical and compressed air, and receives the industrial automatic control input (0 to 10 mA, or 4-20 mA DC) direct current (DC) related signal, and with the aid of a series of components, automatic control valve opening, so as to achieve the fluid pressure in the pipeline, the temperature, the meteor, liquid level and other process parameters of continuous adjustment.
The flow passage of pneumatic diaphragm sleeve control valve is S streamline. The overall work is smooth, allowing large pressure difference, flow specific accurate, low noise and other characteristics. It is especially suitable for large flow, valve before and after the pressure difference is large, leakage requirements are not high in the workplace.
