The BURKERT 62960 (Type 0131) is a direct-acting toggle valve. A variety of seal material combinations are available depending on the application. Thanks to the diaphragm separation between the actuator and valve body, aggressive media such as acids and alkaline solutions can also be safely controlled. The solenoids are moulded with a highly resistant chemical epoxy. The 62960 variant specifically features a brass body, NBR seals, and operates on 230V for 3/2-way distribution (Circuit Function F).

Features

• Direct-acting media-separated valve up to DN 20
• Vibration-proof, block screwed solenoid system
• Robust, service-friendly manual override

Installation and Maintenance

Safety Instructions

• Risk of injury from high pressure: Before loosening lines or valves, switch off the pressure and vent the lines.
• Risk of injury from electric shock: Before working on the device or the system, switch off the power supply and secure against reactivation.

Manual Override

::: caution Loss of O-rings leads to valve leakage. Medium may escape. When manual override is locked, the valve can no longer be electrically actuated. :::

To override the valve manually, press the manual override and turn it 90° clockwise until it stops.
