3" and 4" Grooved and Flanged 90° and Straight Internal Air Operated Emergency Valves with 3" Air Cylinder.

Though higher priced, we strongly recommend Betts Emergency Valves with Viton-B seals, when available, instead of PTFE/Silicone (Tef-O-Sil) seals when used for standard petroleum products, all ethanol products, and all Bio-diesel products. Viton-B seals seldom fail during DOT testing and are not affected by tiny pieces of sediment like PTFE/Silicone (Tef-O-Sil) seals are prone to be.
