Airless Prime Spray Valve, Blow Off Valve 235014 257352 245103 for 395 795 1095 Key benefits Improves turbine response by venting excess boost to atmosphere instead of returning it to the engine. Reduces the risk of unwanted back pressure or boost buildup in the system. Stainless steel construction provides corrosion resistance, durable performance, and a long service life. Can be tuned: adjust spring pressure by turning the of the valve. Compatible with 395, 795, and 1095 systems, using the valve models 235014, 257352, and 245103. What it does Dump valve opens under excess pressure to release boost to the atmosphere, improving turbine behavior and preventing overshoot or backflow into the engine. Maintains stable operating conditions by allowing controlled relief of pressure when needed. Specifications and features Material: Stainless steel for durability and corrosion resistance. Function: Vent excess boost to atmosphere to improve turbine response and protect engine performance. Adjustment: turn spring pressure adjustment. Compatibility: Designed for 395, 795, 1095 systems with valve models 235014, 257352, 245103. Use scenarios Performance tuning on turbocharged 395/795/1095 systems to achieve quicker throttle response and smoother boost delivery. Street driving in boost setups where faster turbine response helps reduce lag and improve drivability. Testing and maintenance situations where reliable venting of excess boost prevents unwanted pressure buildup and engine strain.
