Functional Characteristics
The pressure sensing valve is a three-way module and a pressure controlled bleeder valve and an adjustable spring on the reverse piston. Its function can be normally closed or normally open; The opening of the valve depends on the actual pressure in the two ports through the instrument;
When the sensing pressure signal reaches the set pressure, it controls the output direction of the low-pressure air source. The mechanical structure is stable, reliable, long life and maintenance free. It is used to control other components on high pressure equipment to reach the set pressure. Widely used in petroleum and chemical industry;
Actual pressure protection or control related protective devices under severe conditions such as explosion, no electricity, large temperature difference, wind and sand.
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.
