Bürkert 20107722 (Type 7011) is a direct-acting and compact small plunger valve designed for blocking, dosing, filling, and ventilating neutral gaseous and liquid media. This specific model features a stainless steel body, G 1/8 internal thread, 1.2 mm orifice, and FKM seals. It operates at 24V DC and can handle pressures up to 35 bar. The stopper and the core guide tube are welded together to increase pressure resistance and leak-tightness.

Type 7011 valves feature a slipped-over coil system and allow for simple and fast flange or manifold mounting. In combination with a plug conforming to industry standard form B, the valves satisfy degree of protection IP65.

Pin assignment

Vacuum Applications

In vacuum applications, the existing flow direction must be maintained. Vacuum must therefore always be applied to port A.

Safety Instructions

Risk of injury from high pressure

Before working on the system or device, switch off the pressure and ventilate and empty the lines.

Risk of injury from electric shock

Before working on the system or device, switch off the power supply and secure against reactivation. Always connect the protective conductor and check electrical continuity between the solenoid and the body.

Risk of burns/fire

The solenoid coil can become very hot during continuous operation. Keep the device away from highly flammable substances and media and do not touch with bare hands.
