Oxford Flow - IP Series - Pressure Reducing Valves (PRVs)

High performance pressure reducing valve (PRV)

Water-type construction for DN50-DN300 (2”-12”) pipework


The Oxford Flow IP Series is a unique patented range of pilot-controlled, wafer-type pressure reducing valves (PRVs) developed specifically for water applications.

The lightweight polymer construction uses a durable Acetal resin (WRAS & NSF approved) to significantly reduce weight and remove the need for expensive lifting equipment during installation and maintenance.

Wafer-type installation between PN10/PN16 flanges minimises installation footprint and the design eliminates the main diaphragm, using a piston sensed mechanism to maximise reliability and reduce maintenance costs.

The IP Series offers pilot-controlled accuracy and can also be integrated with actuated systems in smart networks to calm and reduce leakage.
