PRODUCT FEATURES 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" FPT. Outlet Port: 3/8" MPT. Bypass Port: 3/8" MPT. 0-3500 PSI Reviews Featured Products Unloader Block $27.54 Choose Options GP YVB Unloader $172.20 Add to Cart High Flow Pressure Unloader $161.70 Add to Cart VRT Unloader AR Pump $58.57 Choose Options
