OKCVPL Pneumatic small flow needle type control valve

Gv11p single seat pneumatic control valve
Small flow with needle control valve small diameter single seat control valve has the advantages of compact structure, have a streamlined channel, the pressure drop loss small, flow characteristics of high precision. Spool can choose a wide CV value. The seat closed performance of the DIN IEC and the standard control valve equipped with multi spring diaphragm actuator, the structure of small and large output force.
It is widely used in high and low temperature, small flow stability control in high pressure situation.
Patent No.: ZL 20142 X 0134596.
Design features:
Supporting the design - positioner and actuator, with no pipeline connection, improve the overall seismic control valve;
The dustproof ring can prevent external dust and other impurities into the stuffing, destroy the stem and packing surface, causing leakage;
Leakage - regulating valve in accordance with ANSI B16.104 standard.
The double seal, the valve is more safe and reliable;
] gland length equal to the valve stroke, external impurities always can not enter the stuffing box, ensure the packing chamber always clean, stable sealing;
- equipped with multi spring diaphragm actuator, which has the advantages of compact structure, large output force;
