BURKERT 389794 (Type 7011) is a direct-acting and compact small 2/2-way plunger valve. The stopper and the core guide tube are welded together to increase pressure resistance and leak-tightness. This specific model features an M5 threaded port, a 2.0 mm orifice, a stainless steel body, and FKM seals. It operates on 230 V / 50 Hz with a power consumption of 6 W, supporting a pressure range of 0 to 22 bar. In combination with a plug conforming to industry standard form B, the valve satisfies degree of protection IP65.
