Gas pressure regulator VPID 1

dome-loadedsingle-stageanalog

• Dome back pressure regulator for high precision and reliability • easy installation and operation and standardized connection options (NPT/G) allow fast integration into the pipeline system • integrated form control with self-contained medium without external control pressure regulator • stepless regulation without shut-off valve in the output • high user safety due to inherent safe construction • high flow range and high pressures • minimum pressure difference up to 2% (small hysteresis) between opening and closing • maximum accuracy, thanks to large-area membrane (EPDM or FKM) Back pressure regulators are used in process pressure regulation to keep the pressure in a system constant. In this case, an excess medium, which would increase the system pressure, is discharged in a controlled manner. Back pressure regulators are used, for example, to regulate the outlet pressure of a pump in order to protect subsequent valves from inadmissible pressure surges or pulsation. Another application for the Hornung back pressure regulator is the gas overlay of containers and tanks. During the filling of a tank, the pressure in the gas chamber of a gas-supported tank increases so that the gas cushion must be ventilated in a controlled manner and kept constant. Hornung back pressure regulators are used here for a proper ventilation process in compliance with the safety regulations applicable to the entire system. • Flow control with back pressure regulators • As a control valve with a large flow range • Tank overlapping • For the protection of bursting discs • Pump pressure-bearing valves • Pressure bypass valves • Pulsation attenuation
