2S500-50 SUW-50 2'' Inch Flow Control SS304 Diaphragm Solenoid Valve

2S & SUW Series 2/2 Way Direct Lift Diaphragm Normally Closed Solenoid Valve:
This valve is a two-way, normally closed, direct-lift valve and does not require a minimum differential pressure to operate. As shown in the diagrams below, when the coil is de-energized, the plunger and flexible diaphragm sit on the main valve orifice. The working medium flows through a tiny "bleed orifice" and pressurizes the cavity above the diaphragm - this system pressure, along with the spring force, seals the valve. When the valve is energized, the diaphragm is pulled away from the main orifice, allowing fluid to flow through the valve. Since the bleed orifice is dimensionally smaller than the main orifice, the system pressure cannot rebuilt on the top of the diaphragm as long as the main orifice remains open.

Security

Generally, the solenoid valve is not waterproof. When the conditions are not allowed, please choose waterproof type, the factory can be customized.
The highest nominal pressure of the solenoid valve must exceed the maximum pressure in the pipeline, otherwise the service life will be shortened or other unexpected conditions will occur.
Corrosive liquids should be selected from all stainless steel type, and strong corrosive fluids should be selected from plastic king (SLF) solenoid valves.
Explosive environments must use the corresponding explosion-proof products.
