BURKERT Type 7011 is a direct-acting and compact small plunger valve up to DN 2.4. The stopper and the core guide tube are welded together to increase pressure resistance and leak-tightness. Various housing and seal material combinations are available depending on the actual application. A Bürkert-specific flange variant (SFB) enables the space-saving arrangement of valves on a multiple manifold. The range is supplemented by variants conforming to DVGW EN 161 and explosion-proof variants. Push-in fittings can be selected for a flexible hose connection. In combination with a plug conforming to DIN EN 175301-803 shape B, the valves satisfy degree of protection IP65.

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. Observe the applicable accident prevention and safety regulations for electrical devices.
• 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.
