Bailey DV26D 'EVO' Twin Piston Dump Valve - 'D' Type Spring

This DV26D twin piston Bailey Dump Valve with a stronger spring than the DV26 Dump Valve, referred to as a DV26 'D' Type, is designed for turbocharged cars that have fuel injection with an airflow meter or metering unit. The ingenious second piston allows cars to idle perfectly and for the fuel mixture to be unchanged which resolves all the running problems traditionally associated with diaphragm valves. It has a 25mm push on base and comes supplied as standard with a straight 4mm polymer push on vacuum/boost connection. The DV26-D has a 60psi boost capability.
