Product Code : VF--DDW-N35-CU
ZSQP series pneumatic piston shutoff valve is a kind of high efficiency valve, widely used in petroleum, chemical industry, metallurgy, electric power and other industrial fields. With its excellent performance and high reliability, the valve has become an important part of the automatic control system.
How it Works:
When the signal pressure is zero, due to the pre-tightening force of the spring (single action only), the spool is in the initial state (normally open or normally closed). When the actuator receives the signal pressure (0.4~0.6MPa), the spring is compressed to drive the push rod, valve body and valve core to move to the limit position, so that the valve is fully open or fully closed. To make the medium in the pipeline connected, cut off or switch control between pipelines. With two-position three-way electric sample valve, the control of piston type cut-off valve is more convenient and simple.
