Risbridger manufacture the patented and ATEX approved market leading Stage Two Vapour return line Shear Valve, as well as Pressure Vacuum Vent Valves and Tanker Vapour Return Adaptors with integral flame arrestors.

  • Normally open, full-flow design with low pressure drop characteristics
  • Dual opposed piston design avoids partial break interference and leakage, shuts fully irrespective of direction of impact
  • Seals upstream & downstream upon impact
  • Cylindrical body fits through and allows sealing with standard membrane seals
  • Variety of end adaptors available

InnoVent

A huge leap forward in vent performance and testing.

  • Accessibility
  • Water intake reduction
  • Diesel fume reduction
  • Vapour saving

The InnoVent is a new top to bottom redesign of tank vent protection. Utilising low acess points for all the parts that require regular inspection and maintenance.

The system is completed with newly designed maintenance free Vent Caps, positioned at the top of the vent stack.

What does InnoVent do?

  • It allows ground level maintenance of all pressure vacuum vent valves
  • It prevents rain water from entering the vent stack
  • It prevents free circulation of damp air in diesel as well as petrol tanks
  • It collects and removes any condensation in the vent stacks

Where is the Innovation?

  • Access at low level for all maintenance and testing
  • No ladders, aerial platforms, gaiters or lowering of pipes
  • No vapour dumping to atmosphere prior to maintenance
  • During maintenance the system is fully sealed
  • Takes care of working at height regulations
  • Labyrinth design of vent caps prevents water ingress
  • Vent caps are maintenance free
  • Testing of VR system possible at low level
  • Effective vent pipe condensate removal system
  • Low level inspection of diesel air intake filter gauzes

Available Modules:

  • Petrol PVV Module
  • Petrol Vent Cap
  • Diesel PVV Module
  • Diesel Vent Cap
  • Vapour Recovery Adaptor Certified Flame arrestor
  • Adaptors allow fitting to existing manifold systems

Materials:

  • Aluminium
  • Plated mild steel
  • Stainless steel fasteners
  • Nebar gaskets
  • Viton ‘O’ rings

Certified: ISO 16852 CML 16ATEX6163X

Pressure Vacuum Vents

 

Our proven and reliable PRESSURE VACUUM VENT VALVES are the only ones in the industry to have a reliable pressure setting, because it is not controlled by a spring.

• Dead weight poppet – provides accurate relief characteristics
• Linear Teflon coated bearing design – minimal contact area for low breakout force in sub-zero temperatures, drained seat detail prevents ice build up
• Reliable vacuum valve – proven design and materials
• Delrin TM (polyacetal) poppet seat – for best sealing, fuel compatibility and service life
• Environmentally friendly – upward discharge of vapour and minimal operating noise
• Heavy duty construction with anodised finish for long life in extreme environments
• Double layer gauze, seated in groove

Vapour Return Adaptor

 

The smallest combined VR Adaptor and Flame Arrestor available.

Retain vapour in your tanks, and protect the site vapour connection point with our new low profile Vapour Adaptor, Flame Arrestor and Cap to promote retention of vapour and prevent dangerous vapour around VR connection points.

RIS-FLOW-3-MK2-FA-PLUSCAP (Shown)
includes retaining chain, cap retaining clip, captive flat Viton A seal and tamper proof operating key. Overall height is just 173mm

  • Simple cam locking mechanism with tamperproof access key
  • Save cost on lost caps – cap assembly with integral chain/clip
  • Extremely low profile adaptor, flame arrestor and cap, overall height 173mm.
  • No padlock to sieze up
  • Integral EN ISO 16852 / EN 12784 Flame Arrestor
  • Cap includes a captive Viton A flat seal for perfect sealing
  • 3” BSP(P) threaded fitting with leather seal
  • ATEX Certified Assembly and Flame Arrestor

Vapour Loss Reduction

 

During a delivery of fuel to a storage tank, the fuel in the tank becomes aerated and turbulent, causing some of the petroleum to form into its vapour state.

Especially important now we have ethanol blended fuels, Risbridger have designed proven fittings which are simple to fit and provide a method of preventing ‘vapour growth’ and the subsequent loss of petroleum product volume in the tanks.

The following video is a demonstration of a standard product drop to an underground storage tank. The pebbles at the bottom represent the debris at the bottom of the tank:

Diesel Vertivents

 

Suitable for use on un-manifolded diesel tanks sites without Stage 1B or Stage 2 Vapour Recovery. These vent assemblies must not be painted, or used where they may be subjected to impact damage or to risk of stabilised burning.

Features:

  • Double layer gauze (stainless steel mesh) seating in retaining grooves
  • Seating in retaining grooves to prevent vapour by-pass
  • Internal drain holes to prevent icing up, or water entering vent stack
  • Positive upward discharge of vapour from tank
