Functional Characteristics

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

Spring return air opens or closes;

Smaller volume, easy to carry and install in a narrow space;

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.
