Applications:
It is widely used in metallurgy, petrochemical, pharmaceutical, tobacco, rubber, food and medical care, urban construction and environmental protection, plumbing, heating and air conditioning, fire safety, scientific research, landscape irrigation, energy industry and other fields.
Features:
A dual piston valve spool, long life; and diversion to the rapid change; authoritarian coil easily burned; in a vacuum, negative pressure, zero pressure can work. Valve mounting direction unlimited.
Main technical parameters:
| Specifications: | DN1 --- DN300 |
| Body material: | Stainless Steel |
| Medium: | Water, gas, oil, steam, gas, corrosive fluids |
| Medium temperature: | -200 ~ +350 ℃ |
| Media Viscosity: | Less than 50C St (greater than the time to be customized) |
| Protection performance: | Waterproof, explosion-proof (Exd IICT5), anti-corrosion |
| Wiring: | Terminal Block Type; lead type; male |
| Control: | Normally open, normally closed |
| Power supply voltage: | DC24 ~ 127V; AC36 ~ 380V |
| Connection: | Thread, flange (male and special interfaces or add custom adapter) |
How it works:
Entering and exiting: Normally closed: When the coil is energized, the two leads 1,1 and 3 closed. When the coil power, the 2 and 1 off, 1 leads to 3.
Always open: When the coil is energized, 3 and 1 off, 1 leading to 2. When the coil power, the 3 leading to 1,1 and 2 closed.
One into two: When the coil is energized, 1 leading to 2,1 and 3 closed. When the coil power, the 1 and 2 closed, 1 leads to 3.
Binary one: When the coil is energized, the two leading to 1,3 and 1 closed. When the coil power, the 2 and 1 off, 3 leading to a

| Remarks | Products, "DM836" and flange type in "DM836" Work can only do two further | |||||||||
Note: The working principle of a binary valve inlet pressure is not equal two, the need to add check valves.
