The Selub Y valve is a 2-way pneumatic valve with right angled seat, self-lubricated.

In fact, the brass separator head is equipped with a permanent lubrication system.

It is generally used for standard fluids, but it can also be suitable for fluids compatible with brass, contaminated by solid abrasive particles and gases in general. In the latter cases, we recommend checking the compatibility of the fluid using the table, or contacting our technicians.

As with many other Maros products, with the fluid inlet under the shutter, the valve is able to avoid water hammer in the system.

All versions are equipped with an upper aluminum rod to indicate the status of the valve.
