General purpose 2way direct acting and semidirect lift acting valves.
Common applications include water, oil (below 20cst), air, gas, freon, *vacuum, weak acids & alkali.
Available in a body/seal material of brass/NBR or stainless steel/viton.
The coil has an adapter with screw terminals for wire leads.
Simple connect wires to the adapter and plug right into the coil for operation.
Adapters can be removed from the coil for maintenance with no need to detach wires.
Brass/NBR valves are suitable for water, hot water, gas, air, non-corrosive oils and freon.
Stainless Steel/Viton valves are suitable for hot water, acid, alkali, chemical salt, oils and hydrocarbon.
Direct Acting: These valves close or open completely on their own.
This means that they can block the flow of fluid in both directions.
SemiDirect Acting: These valves can only stop flow in one direction.
There is an arrow located on the valve body showing the direction of flow in which it blocks.
In order to prevent backflow when the valve is closed, a check valve must be installed.
