Self-operated Pressure Regulators Type 50 EM Pressure Reducing Valve Application Pressure regulator for set points from 0.2 to 10 bar • Valves G 3/8 and G xh • Nominal pressure PN 16 • Suitable for water and other liquids, air and non-flammable gases up to 50 °C The valve closes when the downstream pressure rises. The regulator consists of a valve, a spring-loaded operating diaphragm and a set point adjuster. Special features • Low-maintenance proportional regulators requiring no auxiliary energy • Wide set point range and convenient set point adjustment • Tight-closing, spring-loaded, single-seated valve, which can be used for upstream pressures up to 16 bar • Suitable for media that do not affect the operating diaphragm and do not cause the materials used to corrode Versions Type 50 EM • (Fig. 1) Pressure reducing valve with connection for a pressure gauge (0 63 mm housing, G V connection) to indicate the downstream pressure. Accessories • Pressure gauge with G V connection, 0 63 mm housing, scale division 0 to 4 bar, 0 to 6 bar or 0 to 16 bar Table 1: Technical data ■ All pressures in bar (gauge) Fig. 1: Options for pressure gauge attachment with Type 50 EM Associated Information Sheet Data Sheet

Principle of operation The plug connection link (6) connects the operating diaphragm (4) and the valve plug (8). The downstream pressure to be maintained at a constant pressure produces a force on the operating diaphragm (4), which is used to adjust the valve plug (8) as a function of the adjusted set point. Installation - The valve can be mounted in any desired position. - Direction of flow must match the direction indicated by the arrow on the body Fig. 2: Functional diagram of Type 50 EM Pressure Reducing Valve 6 Plug connection link 8 Valve plug with soft seal 9 Connection for pressure...
