Description
3 port valve DIRECT ACTION 3PA/3PB Series is built as a balanced pressure seat valve.
■ Features
The 3PA 3PA series of three pressurized direct action, with work pressures from 0.7 MPa to a low -100 kPa vacuum, facilitates the construction of low pressure/vacuum systems.
1. The port can be pressurized from any of the 3 ports.
2. 3 port valve DIRECT ACTION SWITCH 3PB/3PB BETWEEN NA and NC.
3. The seat and packaging of the valve of the rod assembly have the same diameter, so the pressure differential of each port is canceled by the internal hole of the rod assembly and the pressure is balanced both on and off.
