This sturdy cast iron valve is designed to fit most standard 1-1/2 pipe threads and has a 5/8 inch outside diameter which delivers a smooth flow of water with minimal noise. It features a well pressure reducing valve that controls the rate at which water flows into your household pipes, thereby maintaining optimal levels in storage tanks while also protecting pipelines from damage due to excessive pressures or surges from pump cycling or other operational conditions. Additionally, this product has a brass body and diaphragm, which ensures its durability and resists the damaging effects of rust, corrosion, scale buildup as well as sedimentation within the tank itself over time for consistent performance for extended periods of use at home or other industrial settings.
