Stent Pneumatic Driven Needle Valves

The cylinder is driven by low-pressure compressed air (75psi) to control the on-off of ultra-high pressure fluid in the valve body. There are two types: normally open and normally closed. There are 6 types according to the position of valve body connecting port, which can meet various connection needs. The maximum working pressure can reach 60，000 psi (4140 bar) Products with switch position sensing can be provided: HI type, convenient for remote control. The valve body is made of 316 material, and the hard sealing needle matched with the valve port is made of 17-4PH or hard alloy, which is wear-resistant and has a long service life and can meet various working conditions

Functional Characteristics

Pneumatic valve actuators are piston type design, reliable operation and long service life;

Installed on the manual valve to provide remote control function;

Separated valve rod design, easy to adjust, form and replace the valve rod;

The actuator is made of anodized aluminum, which has good corrosion resistance and is lighter.

Leading Feature

STK needle valves provide maximum safety and reliability, even under adverse operating conditions, the valve can be installed in any direction and can effectively seal the gas and liquid media The valve pin and valve stem are of a non-rotating design. Thus, the valve life and reliability are increased. Pressure parts are made of high quality corrosion resistant stainless steel All needle valves recorded the reliability of the serial number. Provide complete traceability of all pressure-retaining components.
