Pilot type solenoid valve

- Apr 15, 2017 -

Principle: When the electromagnetic force, the electromagnetic force to open the pilot hole, the upper chamber pressure drops rapidly in the closure around the formation of low pressure on the formation of high pressure to push the closure of the closure, the valve open; Hole closed, the inlet pressure through the bypass hole quickly chamber around the closing valve to form a low pressure on the lower pressure, the fluid pressure to promote the closure of the downward movement, close the valve.

Features: High upper limit of fluid pressure range, can be installed (to be customized) but must meet the fluid pressure conditions.

2, the solenoid valve from the valve structure and material on the difference between the principle and divided into six sub-categories: direct diaphragm structure, step-by-step diaphragm structure, the pilot diaphragm structure, direct-acting piston structure, Step - by - step piston structure, pilot piston structure.

3, the solenoid valve in accordance with the functional classification: water solenoid valve, steam solenoid valve, refrigeration solenoid valve, low temperature solenoid valve, gas solenoid valve, fire solenoid valve, ammonia with solenoid valve, gas solenoid valve, liquid solenoid valve, micro solenoid valve, Pulse solenoid valve, hydraulic solenoid valve normally open solenoid valve, oil with solenoid valve, DC solenoid valve, high pressure solenoid valve, explosion-proof solenoid valve.
