ZJHP Pneumatic single seat control valve adopts single sealing surface spool structure, applicable for low pressure difference and low leakage requirement. ZJHP Pneumatic single seat control valve adopts double sealing surface spool structure, applicable for low leakage requirement. The body channel is streamlined by S shape with low pressure loss, high capacity,wide regulating range, and high accuracy in flow characteristics. The plug features with guiding area and good vibration resistance. ZJHP Pneumatic single seat control valve is equipped with mult-spring diaphragm actuator and compact in structure as well as big in output force. ZJHP Pneumatic single seat control valve is designed to control a broad variety of fluids, like steam, water, most of the medium and gases.
ZJHP Pneumatic single seat control valve 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.
Single Seated Control Valve has a top-guided unbalanced trim structure, It is a compact and simple structure, easy operation and maintenance which can be used under various applications, especially under normal pressure and pressure drop. Valves of this type are the most economical and reliable.
