Acetal tee shut-off valve with non-return function

John Guest acetal T shut-off valve with non-return

T-shaped assembly that integrates manual shut-off and non-return functions to control a branch of a compatible installation.

Dimensions and connections

• Tubing: 3/8" (9.5 mm)
• Threads: BSP 3/8 male-female (16.5 mm)

Practical application

It combines branching, isolation and return limitation in a single component, reducing the number of parts required in certain water or dispense configurations.

Installation

Depressurize, correctly identify inlet, outlet, branch and the functional direction of the check valve. Prepare the tubes with straight cuts and insert fully.

Maintenance

Check the valve operation, the non-return function, and the tightness of all connections. If the flow is abnormal, first check the orientation and any possible obstructions.
