High Flow UPV’s

RIS-UPV under pump valves were designed to replace tank top check valves, and so prevent leakage from faulty suction lines and pipe-work joints. In the case of a leak in the suction lines the pump will lose prime indicating a problem. The optional stainless steel mesh strainers will protect the check valve and also the dispenser internals.

Our High Flow under pump valves are the leading valves in the market and as well as selling to OEM’s for inclusion on Dispensers, we also sell for retrofit markets to increase safety and pollution protection in fuel line installations.

• Fits ‘Oval’ 2 bolt flanges AND ‘Triangular’ 3 Bolt Flanges, see diagrams above.
• Easier installation due to improved flush fit design
• High flow capacity
• Includes bolts, washers, nuts and gaskets
• Anodised corrosion resistant finish on all aluminium parts
• FEATURES vacuum breaker, drain down feature, and 1/8” BSP gauge point
• TESTABLE includes above features AND poppet lock down clamps, allowing isolation and testing of pipework without disassembly of suction lines

Vapour Shear Valves

Prevents leakage of saturated vapour onto the forecourt if the dispenser is knocked over or impacted. Also prevents vapour from tank farm returning to forecourt. The integral isolator valve allows maintenance staff to safely replace the main valve once it is damaged.

ADBLUE Shear Valves

RIS-SHEAR-ADBLUE valves prevent leakage of Adblue product onto the forecourt when the dispenser is knocked over or impacted. The INTEGRAL one-way valve helps retain line prime. OPTIONAL Under pump valves allows safe replacement of main valve once it has become damaged.

Optional valves and flanges are available for ensuring easy fitment to the dispensers.

Check Valves

Our latest version of the popular ANGLE CHECK VALVES are part of our popular and easy to fit RIS-FLANGE™ range of forecourt products.

The bodies and all other parts are fully compatible with modern bio-fuels.
