Industrial WK20 Valve

The Sunwell WK20 is a diaphragm-type solenoid valve sized for 3/4-inch line connections, designed to control vacuum, water, air, and gases in automated systems. It uses a 24-volt DC coil and is configured as a 2/2-way normally closed (NC) valve, opening when energized and sealing off on de-energization. The valve features an NBR (nitrile) seal in a diaphragm sealing arrangement that provides reliable shutoff and quick response under modest pressures. Supplier listings identify WK20 variants, including WK20L, with the same 3/4-inch footprint, commonly implemented in compact process lines, bench-top test rigs, and other equipment requiring simple, robust on/off control of media. With its diaphragm design and DC coil operation, the WK20 is well suited to automation panels and distributed control systems where space is at a premium and quick actuation is needed.
