Basic Information
The document provides details about a self-operated pressure reducing valve with a piston. The valve is designed to maintain a constant outlet pressure and is suitable for liquids, compressed air, and non-hazardous gases. It offers various flow coefficients (Kv) ranging from 3.5 to 115 m3/h and Cv values from 4 to 94.8 gpm. The valve operates within a temperature range of -10 to 80ºC, with an option for up to 200ºC upon request. It supports flanged or threaded connections and can handle a maximum inlet pressure of 40 barg, with outlet pressures between 1 and 16 barg. Available sizes range from DN15 to DN100.

Materials
The valve components are made from various materials, including ductile iron, bronze, carbon steel, and stainless steel, with specific standards for each part. Notable materials include AISI 316 stainless steel for the body and seat, and NBR or FKM for gaskets and O-rings.

Standard Configurations
The document outlines standard configurations for different valve sizes, providing Kv and Cv values, dimensions in both metric and imperial units, and weights for each size. The configurations cover sizes from DN15 to DN100, with corresponding NPS measurements.

Installation Recommendations
The document includes a standard installation guide, recommending the use of check valves, filters, inlet and outlet pressure gauges, and a safety valve that is ATEX approved.
