The GPR30008 family comprises precision pressure reducing valves designed to deliver stable downstream pressure in fluid systems. Available in three setpoint classes (L, M, H) and in connection variants LJN, MJN, HJN, as well as the combined listing GPR300(GPR30008LJN), these valves are built to maintain accurate regulation across fluctuating inlet conditions. Key benefits Maintains stable downstream pressure for consistent equipment operation and reduced system pressure fluctuations. Protects pumps, manifolds, sensors, and downstream devices from overpressure and hydraulic shocks. Adjustable setpoint enables flexible system design; easy field calibration to match changing requirements. Compact, durable construction supports installation in tight spaces and in demanding environments. Offers multiple variants to suit different connection options and pressure ranges, improving compatibility with existing systems. Key attributes Functionality: precision pressure reducing valve that lowers inlet pressure to a controlled downstream level. Variants: GPR30008L, GPR30008M, GPR30008H and corresponding LJN, MJN, HJN variants; includes listing GPR300(GPR30008LJN). Size and compatibility: available in multiple nominal sizes; designed for standard piping connections commonly used in plumbing and process lines. Material: built for durability and reliable operation; specific materials and trims vary by variant and are defined in the product datasheets for these models. Performance: engineered to provide accurate, stable regulation across varying inlet conditions; performance characteristics differ by model (L, M, H) and connection variant (LJN, MJN, HJN). Applications and use cases Residential water supply: regulate pressure from the main to a safe, consistent level for water heaters, fixtures, and appliances. Commercial and institutional plumbing: protect boilers, cooling loops, and manifolds by maintaining a steady downstream pressure. Irrigation and process water systems: ensure uniform flow to sprinklers, meters, or treatment equipment in outdoor or industrial settings. Notes for selection and installation Review the specific model variant (L, M, H) and connection option (LJN, MJN, HJN) to match desired pressure range and pipe connections. Refer to the official datasheets for exact inlet/outlet sizes, materials, and performance specifications to ensure proper fit and compatibility with your system. Consider the installation location and accessibility for future setpoint adjustments and maintenance.
