Powerful and service reduced Dome Pressure Regulator applicable for mounting in pipe- ^_0 158works. DR2.3 - F01/B7 subject to change Benefits • process reliability by high pressure stability in case of withdrawal fluctuations • applicable for almost all gases • accurate dynamic regulation • high flow rate • available in brass or stainless steel (ES) • integrated pilot pressure and manometer connections • remote control by extern pilot pressure regulator or proportional valve • several gas supply can be central regulated to the same working pressure • Balanced Seat Design (BSD) for better control precision Options • mounted pilot pressure regulator • inlet- and outlet pressure manometer with individual scale • inlet- and outlet connections (soldering-, welding- or clamp fittings) • complete mounted with functional- and leak test Operation / Usage Dome pressure regulator are especially suitable for process supply in pipe-works and system engineering. Independent of withdrawal fluctuations the stability working pressure guarantees a constant gas concentration and quality of the down stream processes. Additionally the use in case of high flow rates at low pressure drops is recommended. Function The dome pressure regulator is used in combination with pilot pressure regulator (or proportional valve) for adjusting the required working pressure (outlet pressure). It's possible to use the regulated gas (own medium) or foreign gas as supply of pilot pressure regulator by option. Maintenance Annual testing of body leak tightness is recommended. Replace wearing parts of at least 1-3 years. Premounted Maintenance-Kit on request. Approvals Company certified according to ISO 9001, ISO 22000 and PED 2014/68/EU Module H Cleaned for Oxygen Service according to: - EIGA IGC Doc 13/12/E: Oxygen Pipeline and Piping Systems Other models, options and accessories available on request.
