Functional Characteristics

The hydraulic pressure is used as the power to drive the oil cylinder, so as to control the on-off of ultra-high pressure fluid in the valve body.;

There are two forms: normally closed and normally open;

There are 6 types of valve body connection port positions to meet various connection needs;

Operating temperature range: - 25 ℃~65 ℃ (- 13 ° F~149 ° F);

Working medium: gas, oil and water;

The valve body is made of 316 material, and the valve needle is made of 17-4PH or hard alloy, which is wear-resistant;

Long service life, meeting various working conditions.

Leading Feature

STK needle valve provides maximum safety and reliability. Even under adverse operating conditions, the valve can be installed in any direction and can effectively seal gas and liquid media.

The valve needle and valve stem are non rotating design, which increases the service life and reliability of the valve. The pressure bearing parts are made of high-quality corrosion-resistant stainless steel.

The reliability of serial number is recorded for all needle valves, and the complete traceability of all pressure retaining parts is provided.
