Overview

The ZJHM pneumatic thin film sleeve regulating valve is widely used due to its good stability and simple maintenance. It can be designed as a balanced type to eliminate most of the static unbalanced forces on the valve disc and has a certain hindering effect, which can reduce the vibration caused by fluid flow and can be used for pressure difference ..

Product Details

ZJHMPneumatic thin film sleeve regulating valveDue to its good stability, simple maintenance, and wide application, it can be designed as a balanced type to eliminate most of the static unbalanced forces on the valve disc, and has a certain hindering effect, which can reduce the vibration caused by fluid flow. It can be used in situations with relatively large pressure differences, and can choose multi spring pneumatic diaphragm mechanisms or electric actuators.

Product Features

The characteristics are as follows:

1. Adopting a balanced core, with small unbalanced force, allowing for large pressure difference, and stable operation.

2. The large guiding surface of the valve core can improve the oscillation caused by eddy currents and impacts, and reduce damage.

3. Reduce noise by about 10bd compared to ordinary single and double seat regulating valves.

4. The structure is simple and easy to assemble, disassemble, and maintain.
