Unloader K7.3 6.6-10 GPM 3500 PSI

This unloading valve is a flow-through design and should be mounted on the discharge line of the pump in any position (vertical or horizontal) which allows easy access to the adjusting bolt. A pressure gauge should be installed on either side of the port of the unloader to accurately read pressure during adjustment. Minimum 5% bypass is required for proper operation. Features: All stainless and brass internal parts. No external moving parts or springs. Unique balance principle: eliminates high pressure in all lines while unit is in bypass mode. Eliminates pressure peaks normally generated by conventionally designed unloaders. Dual gauge ports. Maximum Temperature: 165 F. Inlet Port: 3/8" BSP. Outlet Port: 3/8" BSP. Bypass Port: 3/8" BSP. 0-3500 PSI
