Flow-Sensitive Pressure Regulation for High-Pressure Water Systems
The K1 Pressure Regulator Unloader Valve is engineered to deliver precise flow-sensitive pressure control for high-pressure cleaning, pumping, and industrial water systems. Designed for reliability under demanding conditions, this valve supports flows from 9–41 L/min with a maximum pressure of 3600 PSI, making it suitable for a wide range of commercial and industrial applications.
Constructed from durable brass and stainless steel, the K1 unloader ensures long service life while resisting corrosion and wear. Its smart flow-sensitive design automatically regulates system pressure, preventing spikes and protecting pumps from overload. Equipped with 3/8" BSPF inlet, 1/2" BSPM outlet, 1/2" BSPM bypass, and 1/4" BSPF gauge ports, it integrates effortlessly into standard high-pressure setups.
