Key Specifications / Features

BRIEF INTRODUCTION

The ZJHP Pneumatic single seat control valve applies with the top-guided structure, and equipped with the multi-spring diaphragm actuator. It has many advantages such as compact structure, light weight, quick action, shape flow channel, less losses of the pressure reduction, accurate flow characteristic, convenient installation and so on. This series valves can be widely used in controlling the medium like gas, liquid, steam and so on, and keep the working value like the pressure, flow rate, temperature, liquid level at the specific value, especially suit for the working condition of small allowable leakage and small differential pressure.
