In contrast to conventional screw-adjustable RV water pressure regulators, this regulator features an enhanced adjustable hand wheel. No tools are required; simply use your hand to pull up the knob and turn it to adjust the water pressure. Turn clockwise to increase pressure, and turn counterclockwise to decrease pressure. RV water pressure regulating valve is made of lead-free brass treated by hot casting process technology. Each batch of regulators is tested to contain less than 0.13% lead, well under the NSF requirement of 0.25%. The regulator's inlet screen helps to filter out debris and other impurities. Designed with 3/4-inch GHT female inlet and 3/4-inch GHT male outlet, this regulator is compatible with standard water sources and RV hoses. The RV water pressure regulator has a pressure range of 0–160 PSI, with a factory setting of 45 PSI. The pressure gauge provides clear visibility of the water pressure. This regulator includes an inlet screened filter to prevent particle blockage and is suitable for applications such as home use, travel trailer camping, gardening, and plumbing systems.
