The RIS-VENT2 is a high-performance screw-on pressure vacuum vent valve designed for Stage IB and II vapour recovery sites.
Constructed from anodised aluminium with Viton A (FKM), Delrin (polyacetal), and stainless steel components, it ensures durability in harsh fuel-handling environments.
The dead weight poppet and linear Teflon-coated bearing enable accurate relief and low breakout force, even at sub-zero temperatures.
Its drained seat design prevents ice buildup, enhancing reliability in extreme conditions.
The valve offers an environmentally responsible upward vapour discharge and is 100% factory-tested to ATEX standards.
