Applications:
Military, nuclear industry, Shipbuilding Industry, petrochemical, power, chemical, light industry, machinery, research, gas pipelines, industrial furnace, plumbing media automation control and other fields.
Product Features:
Small size, attractive appearance; coil is energized directly start the spool, the valve is closed by spring return; zero pressure start; leakage is zero; authoritarian coil, easily burned; valve mounting direction unlimited.
The main technical parameters:
Specifications: DN8 ~ DN300
Body material: cast iron body, cast steel body, stainless steel (cast iron body and steel body without being able in corrosive fluid on)
Suitable medium: water, gas, oil, steam, gas, corrosive fluids, etc.
Temperature range: -20 ~ +200 ℃
Medium viscosity: less than 50C St (greater than to be customized)
Protection performance: waterproof, explosion-proof (Exd IICT5), corrosion
Wiring: Terminal Block type; Leaded; Plug
Control mode: NC
Power supply voltage: DC24 ~ 127V; AC36 ~ 380V
Connection: internal thread, flange (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.
