Import zero differential pressure explosion-proof solenoid pneumatic valve product is introduced

Germany LIT brand solenoid pneumatic valve, it is a direct acting and pilot operated the principle of combining, when the inlet and outlet no pressure difference, after electrify, electromagnetic force the lead directly to the small pneumatic valve and main valve closed, in turn, lift, pneumatic valve to open. When the inlet and outlet at startup pressure difference, after electrify, forerunner of the electromagnetic force small pneumatic valve, the main pneumatic valve inferior vena pressure rising, the cavity pressure drop, which using the differential the main pneumatic valve opened up; Power outages, the forerunner of pneumatic valve using the spring force or medium pressure push off, move down, to close the pneumatic valve. Features: on the zero differential pressure or vacuum and high pressure, to * action, but power is larger, requirements must be installed level.
import zero differential pressure solenoid pneumatic valve product use:
import zero differential pressure solenoid pneumatic valve used for various normal temperature, medium temperature, atmospheric pressure, medium-pressure occasions, apply to pure gas fluid, especially in the air, water, gas, gas, diesel, low pressure steam, hot water pipeline automatic control; Widely used in washing equipment, biological, pharmaceutical, refrigeration, hvac, water plant and environmental protection water treatment and other industries, is the automation control engineering, project and equipment supporting the preferred products.
import zero differential pressure solenoid pneumatic valve control mode:
normally closed: when energized coil, the forerunner of pneumatic suction valve core, the guide hole is opened, the pneumatic chamber pressure relief valve, piston, powered by inferior vena medium pressure solenoid pneumatic valve to open. When coil power, leading by the spring return pneumatic valve core, the guide hole closed, pneumatic valve cavity on pressurized by the piston orifice and reset spring of thrust, solenoid pneumatic valve closed.
normally open: when energized coil, the forerunner on spring return pneumatic valve core, the guide hole closed, the pneumatic valve cavity by a piston booster orifice and reset spring of thrust, electromagnetic air valve is closed. When the coil power, leading by the spring return pneumatic valve core, the guide hole is opened, pneumatic chamber pressure relief valve, piston, powered by inferior vena medium pressure solenoid pneumatic valve to open.
