PP-H Pressure Reducing Valve PROGEF Type 582 SDR11 PN10

  Datasheet (PDF)

The Georg Fischer PROGEF Standard Type 582 pressure reducing valve reduces and stabilises downstream pressure to a preset, constant value inside industrial thermoplastic piping networks. The body is produced in beta-PP-H (isotactic polypropylene homopolymer) and the valve works as a direct-acting regulator: medium-controlled differential pressure counterbalances inlet pressure peaks and line fluctuations, with the hydraulic forces acting on the elastomeric diaphragm assembly held against an adjustable, calibrated stainless steel spring, so the outlet pressure stays stable regardless of upstream demand.

The SDR11 spigot ends are prepared for conventional butt fusion and for high-purity infrared (IR) fusion, so the Type 582 joins metric PROGEF PP-H piping across outer diameters from d20 mm to d63 mm (DN15 to DN50). A central union nut made entirely of plastic keeps exposed metal fasteners out of contact with aggressive media and corrosive atmospheres, while threaded stainless steel inserts in the valve base allow rigid mounting on pipe brackets and supports without transferring mechanical stress into the thermoplastic body. Connection ports on both sides accept optional pressure gauges for monitoring either side of the regulation point.

Rated PN10 (up to 10 bar at 20 degrees Celsius), the valve covers a set-point range of 0.5 to 9.0 bar. Wetted sealing elements are EPDM or FKM, combined with a PTFE-faced diaphragm for chemical resistance to acids, alkalis, salts and effluent streams — the usual duty in chemical processing, water treatment, electroplating and process manufacturing plants. BigWeld supplies this valve as an authorised Georg Fischer distributor.
