IP-X flanged 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.


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

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.

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.

*Other sizes and construction materials can be made available on request, contact Oxford Flow for more details

Value proposition
Feature:Compact and light weight polymer valve body.
Benefit: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.
Feature:Does not have a diaphragm – one of the leading causes of leakage in networks.
Benefit:Inherently more reliable design, with minimal moving parts susceptible to failure.
Value proposition:Reduces maintenance OPEX and the overall cost of ownership.
Feature:Unique design that can operate across a wide flow range from drip tight closed to fully open without instability.
Benefit: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.
Valve variations

IP valve

  • The IP in a polymer wafer body that can be installed between PN10/PN16 or ANSI150 flanges.

IP-K valve

  • For mobile pressure control applications, the IP-K offers the same compact, light weight polymer valve body but with integrated handles, feet and quick-fit connections.
  • Ideal for accurately controlling pressure from hydrants into more sensitive systems.

IP-T valve

  • For water applications, the IP-T is configured for tank level control applications and the lightweight polymer construction uses POM-C.
  • The axial flow design eliminates the main diaphragm to maximise reliability and reduce maintenance costs.

IP-W valve

  • The IP-W Series pressure regulator range offers excellent pressure control for liquid distribution and transmission applications.
  • The patented, compact construction significantly reduces weight and the need for expensive lifting equipment during installation and maintenance.
