 Product Feature

The 3PA series of direct-acting, pressurised three-port valves, with working pressures from 0.7 MPa to a low vacuum of -100 kPa, facilitates the construction of low-pressure/vacuum systems.

● Switchable between NO and NC.

● Port can be pressurized from any of 3 ports.

● The stem assembly valve seat and packing have the same diameter, so each port pressure differential is canceled by the stem assembly’s through hole and pressure is balanced at both ON and OFF.
