Check Valves and Shear Valves

Risbridger have been designing and producing Check Valve and Vapour Shear valves for many years.

Available in several configurations for use with three bolt or two bolt flanges, and in various materials including Stainless Steel, for use with Adblue or other corrosive fluids.

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.

• Full flow low pressure drop design, normally open
• Avoids partial break interference and leak condition with dual opposed piston design
• Seals upstream and downstream on impact
• Cylindrical body fits through and allows sealing with standard membrane seals
• SIRA Certification: II 1/2 G SIRA 06ATEX9258U
• Includes brackets, bolts, isolator valve and instructions
• 3920 N (400 kgF) break force
• Patented design (UK: GB2342709, US: 6,802,332, EU: EP1,222,423,B1)

Stainless UPV’s

RIS-UPV-TEST-SS is a stainless steel valve with poppet lock down feature for pipework testing.

SUITABLE FOR USE WITH ETHANOL FUELS AND ADBLUE

  • Poppet lock down clamps allowing isolated under pump pipework testing without disassembling
  • Improved flush fit sandwich design for easy installation
  • High flow capacity
  • Viton seals
  • Multi function test point providing
    a) vacuum break
    b) drain down
    c) gauge connection – 1/8” BSP
  • Each assembly includes bolts, gaskets, filter and instructions

​MATERIALS:
Stainless steel, delrin, viton seals

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.

LPG Shear Valves

RIS-SHEAR-LPG1 shear valves prevent leakage of pressurised product onto the forecourt when the dispenser is knocked over or impacted.

Suitable for:
Liquid Petroleum Gas product lines (LPG, GPL, LP Gas, Autogas)

• Full flow low pressure drop design
• Avoids partial break interference and leak condition with displaced ball design
• Seals upstream and downstream on impact
• Consistent 420 Nm bending moment break
• 25 Bar pressure rating with 12:1 safety factor
• Includes brackets, bolts and instructions
• Non-spark brass construction, nitrile seals
• Optional end fittings and mounting kits available – including isolator valves

SIRA Certified to ATEX and EN 14678-1 II 2 G
Patented design (UK: GB2342709, US: 6,802,332, EU: EP1,222,423,B1)

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.

RIS-FLANGE2-20ACV – 2″ BSP FEMALE inlet and outlet (PCat flanges are suitable for direct attachment to the side flange of the body)

RIS-FLANGE2-15ACV – 1.5″ BSP FEMALE inlet and outlet (PCat flanges are suitable for direct attachment to the side flange of the body)
