IP Liquid Regulator

The IP water pressure control valves marked a world first – a 100% polymer valve body for water pressure control. WRAS and NSF certified, the IP is smaller and lighter than alternatives and offers outstanding performance and reliability for use with potable water and process fluids.


The IP series pressure control valve can be configured for pressure-reducing, pressure sustaining and tank level control applications.

Eliminates the main diaphragm

The NSF and WRAS certified axial flow design eliminates the main diaphragm, the leading cause of failures. Instead it utilises a piston-sensed mechanism to maximise reliability, reduce maintenance costs and optimise total cost of ownership. The valve also boasts market leading minimum head-loss performance.

Significantly reduced weight

The lightweight polymer construction uses POM-C Acetal to significantly reduce weight and minimises the need for expensive lifting equipment during installation and maintenance. In addition, wafer-type installation between PN10/PN16 or ANSI150 flanges minimises installation footprint.

Value Proposition


Compact and light weight

polymer valve body


Can be easily installed in smaller chambers and retrofitted in existing chambers with limited space.

Value proposition

Offers the ability to extend pressure management to more of the network without disruptive, additional construction and CAPEX.


Does not have a diaphragm

one of the leading causes of leakage in networks.


Inherently more reliable design, with minimal moving parts susceptible to failure.

Value proposition

Reduces maintenance OPEX and the overall cost of ownership.


Unique design that can operate across a wide flow range

from drip tight closed to fully open without instability


Tolerates a variety of operational and hydraulic challenges across the water network such as fire flows.

Value proposition

Minimises the need to resize valves as network flow rates and hydraulic conditions change, improves reliability and reduces operational downtime.
