Introduction

Pressure Relief Change Over Manifold
Change over manifold’s are a statutory requirement in many states and countries, their main purpose is to ensure that when a pressure relief valve is removed from a system for  regular servicing and inspection the plant can continue to operate safely as the second pressure relief valve has been brought in service.

The RELIEFMASTER™ changeover manifold has been designed to provide continuous system protection in the event of PRV servicing or rupture. Each manifold has a wide internal chamber to maximise flow and assure high relief valve discharge capacities. Internally a brass to metal seat guarantees positive isolation independent of position, while providing exceptional durability. Suitable for all fluorinated refrigerants and oils to a maximum safe working pressure of 3500kpa (500psi).
