The GPR family precision pressure reducing valves provide accurate, stable downstream pressure in fluid systems. The models GPR40015, GPR20006, GPR30008HML, and the variant GPR30008M are designed to regulate inlet pressure to a user setpoint, helping protect downstream components and ensure consistent process conditions. Key benefits Consistent downstream pressure: maintains a steady outlet pressure despite fluctuations in upstream supply and varying flow demands. Downstream protection: reduces the risk of overpressure in valves, sensors, actuators, and process equipment. Easy adjustment and reliable performance: straightforward setpoint adjustment with predictable regulation to support stable operations. Compact and adaptable: compact footprint with model options that fit a range of installation spaces and piping configurations. Durable construction and long service life: designed for robust industrial use with materials and finishes chosen for reliability in common service environments. Modeldriven flexibility: available variants (GPR40015, GPR20006, GPR30008HML, and GPR30008M) to match different port sizes and setpoint ranges while sharing core regulation technology. Key attributes Function: precision pressure reducing and regulating valve that lowers upstream pressure to a controlled downstream setpoint. Compatibility: suitable for standard piping connections; model variants cover different port sizes and installation needs. Refer to the datasheet for exact configurations and allowable media. Size: compact footprint with port configurations chosen by model; exact dimensions vary by variant. Material: body and internal components are specified per model; material details are provided in the product datasheet. Performance: designed for precise regulation with stable outlet pressure across varying flow rates and upstream pressure changes; performance is model dependent and specified in the datasheet. Adjustability: downstream pressure setpoint configurable to meet system requirements; check model documentation for adjustment range and method. Model variants and compatibility GPR40015, GPR20006, GPR30008HML, and GPR30008M represent different port configurations and setpoint ranges within the GPR precision valve family. Selecting the correct model depends on your installation size, flow requirements, and desired setpoint. Consult the product datasheet or technical support to confirm compatibility with your piping and process needs. Applications and use cases Building services and municipal or commercial water systems: install to regulate mains pressure entering internal distribution networks, protecting fixtures, valves, and appliances from pressure surges. Industrial process piping: use where a stable downstream pressure is required for consistent process control, dosing, mixing, or downstream equipment performance. Equipment protection in distribution manifolds: place at strategic points in a pump or header network to maintain a safe, repeatable outlet pressure for multiple branches. General fluid system stabilization: employ in systems with variable demand to reduce pump cycling and improve overall stability and efficiency. Installation and maintenance considerations Orientation and mounting: install per model specifications; check recommended orientations and mounting supports in the datasheet. Inlet pressure and setpoint: ensure upstream pressure and target downstream pressure fall within the model's rated range; improper settings can affect regulation quality. Connections and accessibility: use standard piping connections appropriate for the chosen model; provide access for adjustment, inspection, and periodic maintenance. Inspection and servicing: schedule routine checks of setpoint accuracy and valve operation in accordance with the product datasheet or maintenance guidelines, and components as recommended by the manufacturer. Notes for procurement and installation The GPR40015, GPR20006, GPR30008HML, and GPR30008M variants share core pressure regulation technology while offering different port sizes and setpoint options. For a precise fit, verify port sizing, setpoint range, materials, and attachment methods with the official datasheet or product specification sheet. This description reflects the product family and its stated purpose without altering any specifications. For exact technical details, refer to the modelspecific datasheet and documentation.
