IP-X Liquid Regulator

The Oxford Flow IP-X is a unique, patented range of pilot-controlled axial flow pressure regulators developed specifically for liquid applications in a range of configurations, including pressure reducing, sustaining, sustaining/relief and tank level control.

Flange availability

The IP-X Series valves are available with PN10-25 or ANSI #150 flanges constructed from stainless steel*.

Eliminates requirement for large main diaphragm

The axial flow design eliminates the requirement for a large main diaphragm and instead uses a piston sensed mechanism which maximises reliability and reduces maintenance costs.

Controlled accuracy

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

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.

Product Variations

Complete with integrated handles, feet and quick-fit connections the Oxford Flow range of IP-K pressure reducing valves (PRVs) are ideal for mobile hydrant service.
The IP-W Series pressure regulator range offers excellent pressure control for liquid distribution and transmission applications.
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 Intelligent Water Valve offers all the benefits of the IP valve technology with integrated sensor technology for fully autonomous, intelligent pressure and flow control.
