2 way SUS 304 water weak acid and alkali Solenoid Valve
emi- direct acting(1/2" to 2") solenoid valves and do not require a minimum operating differential pressure. As shown below when the coil is energized (right diagram), it lifts the solenoid plunger, which normally rests on the valve seat and lifts it to open the main valve orifice. When the coil is de-energized (right diagram), the spring force the plunger return to the valve seat to close the valve orifice.
[Technical Specifications ]
-- Media: Gas, Water, Air, Oil (below 20cst), Weak acid & alkali, Vacuum

--Function type: Normally Closed (N/C), Normally Open(N/O)
--Temperature: -5 ÷80ºC
--Mode of action: Semi-direct lift type
--Body material: Stainless
-- Sealing material: NBR
--Protection class: IP65
OPTIONS
EPDM (E): suitable to water, hot water, gas, Freon, the MAX. 110ºC; In case you choose EPDM, please state "E" in your order.
Viton (V): suitable to hot water, acid, alkali, chemical salt, oil and hydrocarbon; the MAX.130ºC. In case you choose Viton, please state "V" in your order.
How to order
Valves available in normally closed and normally open constructions. Available in either AC or DC operated with plastic bodies/ stainless steel/ tube/plunger / soft magnetic alloy core. therefore the price is lower compared with that of brass and stainless steel.
