 Applications:

 
It is widely used in petrochemical, electrical, mechanical, medical, scientific, filling, buildings, industrial furnace, plumbing media automation control and other fields. Suitable for medium and large caliber, working pressure from zero to low pressure in the piping system.
 
Product Features:
1, direct-acting combined with a pilot valve
2, the valve are stainless steel piston, piston rings will not be stuck impurities in the medium
3, the coil spool and pull the piston starts at zero pressure can work
4, special plastic coil, improve the reliability of the valve and waterproof, moisture-proof, easy to burn
5, long-stop action restart action as sensitive, long life
 
  Zero pressure start, low binding; piston structure, stable performance; authoritarian coil, easily burned; suitable for low pressure, large diameter piping systems. Installation must be installed vertically.
 
The main technical parameters:
 
◆ Control: Normally open, normally closed, self-retaining.
◆ Power supply voltage: DC12 ~ 220V; AC24 ~ 380V.
◆ Body material: steel, stainless steel, tetrafluoroethylene.
◆ Applicable medium: water, gas, oil, corrosive fluids.
◆ Pressure range: 0 ~ 0.6MPa
◆ Temperature range: -20, +80, +120, +200, +250.
◆ Medium viscosity: less than 50C St (greater than to be customized).
◆ Protection Performance: dustproof, waterproof, explosion-proof. According to the conditions selection.
◆ Wiring: Terminal Block type; Leaded; plug-in.
◆ Connection: flange, welding, internal thread (male and special
             Interfaces or add custom adapter).
 
How it works:
Normally closed: When the coil is energized, the electromagnetic force to open the pilot hole, the main valve piston chamber pressure drops, and thus the use of suction pressure and the electromagnetic force moving the pilot valve connected movable main piston, valve port open; de-energized by a spring reset Close the pilot hole, the main piston chamber pressurized, pushing the main piston moves down, the valve closes. Normally open and normally closed opposite.
