The DEF Drain Valve is available in a stainless steel version for Diesel Exhaust Fluid (DEF) tank applications. The DEF Drain Valves uses the same ball valve design, and is available in several thread sizes. A new lock nut feature on the SS version allows the valve’s final position to be orientated perfectly during installation. A hose can be attached to drain the DEF to prevent it from any spills. As DEF is highly corrosive, the SS version DEF Drain Valve is designed to withstand these properties, using all SS 304 components and a Viton O-ring to seal.
