Collection:Shut-Off Hand Valves With Push-In Fittings

These valves allow shut off control in a compressed air system. The connection ports are designed with different combinations: an inlet and an outlet ports with push-in fittings, the inlet port with a threaded nipple fitting and the outlet port with a push-in fitting, the inlet port with a push-in fitting and an outlet port with a threaded nipple fitting. There is also a male threaded valve in this category.

These valves can be two or three-directional. The three-directional valves have a residual pressure release function. This means that they vent the compressed air out after closing which relieves the system of the built-up pressure. The two-directional valves do not have the relief function, which is useful in applications with for example tanks which need to keep the residual pressure.

To operate the valve, use a quarter-turn handle. Turning the handle 90 degrees opens or closes the valve by moving a spool, which has lands and valleys, upward or downward. The land is a thicker part of the spool, which closes the valve and prevents the flow while the valleys allow flow when they are positioned between the ports.
