The RIS-SHEAR Vapour Shear Valve offers critical vapour containment at fuel dispensers, preventing vapour leakage if impacted or sheared. Designed for forecourt safety, this patented valve halts vapour return from tank farms and ensures minimal downtime with a built-in isolator for quick valve replacement.

Engineered for high-flow performance (up to 150 l/m), this normally open valve operates across -5 to +35 mbar pressure range with extremely low pressure drop. Dual opposed pistons provide upstream and downstream sealing on impact, avoiding partial break leaks. Its compact cylindrical body ensures compatibility with standard membrane sealing systems.

Certified to ATEX standard SIRA 06ATEX9258U, this valve supports hazardous zone installations, and is constructed from robust materials including anodised aluminium, stainless steel, and Viton A seals. Supplied complete with mounting brackets, bolts, and full installation instructions.
