PIV Model


The PIV model has a Pressure Isolation Valve mounted in the outlet distribution manifold. When closed this valve isolates the pressure gauge and outlet port from the rest of the power unit system, allowing the gauge to accurately monitor the outlet test pressure. An additional port is provided in the manifold to which a pressure transducer or pressure recorder can be connected. When not in use this port can be plugged off.



If required please add suffix PIV to the

model reference number. e.g. APU-1-107B-PIV
