The PMBV Series Ball Valve is designed as a panel mount diverter valve. The middle port is common. The 90 degree handle rotation directs the flow to the open port, shutting off the other port completely. The handle can be orientated in four position and can be installed or removed while the valve is under pressure. The panel mount requires a 0.750 hole through a maximum panel thickness of 0.170". Two of the four available screw boss locations will secure the valve, screws are not supplied.
