Gas Pressure Regulator HON 200.
Application • Gas supply to municipal, industrial and individual consumers • Regulator for low-load rails in larger gas pressure regulating stations • Standard version can be used with natural gas and all non-aggressive gases • Oxygen version, open-air version and other special versions on request
Characteristics • Simple, maintenance-friendly design • Installation of different valve seat diameters is possible • Can be used for large turn down ratios • Use of proven pilot series HON 610 (RS 10 d) and HON 650 • Can be used for electrical automation mechanisms with a proportional stage.
The HON 200 gas pressure regulator has the task of keeping the outlet pressure pa constant within certain tolerances at the measuring point in the outlet-side line system, regardless of fluctuations in the inlet pressure and consumption. It is comprised of the “main valve” assembly (consisting of main valve and actuator) and the “pilot” assembly (2-stage version with load limiting stage and pilot control stage). In addition, a fine mesh filter is installed upstream to protect the pilot. The design of the gas pressure regulator HON 200 is maintenance-friendly.
By unscrewing 4 screws the complete functional unit (consisting of actuator and main valve) can be removed from the actuator housing.
The pressure difference between inlet pressure and outlet pressure is used as auxiliary energy. Through the adjustable auxiliary energy the static amplification can be influenced and the gas pressure regulator can be adapted to the conditions of the regulating line. (See also Honeywell document, “General Operating Manual for Gas Pressure Regulators and Safety Devices”). The outlet pressure to be regulated is detected at the measuring point and fed to the pilot via the measuring line of the pilot control stage of the pilot. Here the outlet pressure acts on a sensitive diaphragm system and is compared with the adjustable setpoint value (force of the setpoint spring). According to consumption the loading pressure is changed in the sense of an adaptation of the actual outlet pressure value to the setpoint. In this regard the loading pressure acts on the main valve via the actuator and thus automatically executes the flow-through changes necessary for a constant outlet pressure pa.
The main valve (valve) is designed for sensitive and stable outlet pressure regulation with a parabolic cone.
Six valve seat sizes are available for adaptation to the respective operating conditions. The maximum permissible inlet pressure is determined by the size of the valve seat diameter. The regulator has a sealed closure at zero consumption.
