PA VB 85/310 Rv and General YUB21405 blue spring trapped pressure unloader valve. At gun closure, the waterflow is discharged in bypass reducing the pressure in the system upstream of the valve

Featuring:
• Dynamic seals made up of O-ring and Back-up ring
• Optimized internal passages that guarantee reduced pressure loss
• Anti-rotation device of the piston positioned inside the valve and obtained by an hexagonal sector of the piston itself
• O-rings of the fittings positioned upstream to the thread : no risk of fittings ejected in case of overpressure
• Double feed connection
• Suitable for recycled water and strong detergents
