Available in both cast and fabricated bodies, Crispin's Universal Sewer Valve is ideal for even the most highly corrosive applications. It stays open to fully exhaust air volume, and comes in both short and long body styles. Stainless steel internals add extra strength and durability to the design, reducing the need for frequent backflushing. In addition, the valve has a field replaceable seat that eliminates the need for valve disassembly during routine maintenance. Engineered and manufactured in the U.S., its heavy duty construction meets or exceeds current industry specifications. Sizes 2'' thru 6'' are available.
