The Indu-Tech Level Transmitter Isolation Valve features an optimized design that enables accurate level measurements, simple installation, and Swirl-Purge in-situ flushing feature which ensures a clean and clog-free passageway directly to the level transmitter diaphragm. The isolation valve utilizes a close captured seated ball design, which ensures that the process medium does not build up internally. Each valve is tested under strict quality standards for bubble tight design.

The isolation valve is designed with a 90-degree 1/4 turn on/off handle. This design allows the user to open or close the handle on demand, even in situations where the valve has not been activated over a long period.

The 1/4in port provides instrument side pressure relief and can be set up to provide pressure relief for some applications. This port can also be used for level transmitter calibration without having to remove the level transmitter. Closing the isolation valve allows the technician to pump metered air into the instrument side cavity and calibrate the instrument.

Independent bolting patterns allow for the isolation valve to be mount to the tank and the level transmitter. Separate mounting plates ensure a safe working environment when removing a level transmitter from the tank during routine operations.
