DOME PRESSURE REGULATOR SET 737 LE-HD/S FOR CO2 Complete solution - own medium controlled High-performance dome-loaded pressure regulator-set. For high and varying flows requiring maximum pressure stability. A complete solution, applicable as a manifold pressure regulator per DIN EN ISO 7291. Features ●● Pilot Control Tube (PCT) Annual testing of body leak tightness is recommended. Depending on application, moving wetted parts may need periodic replacement. ●● Balanced Seat Design (BSD) Device-specific Maintenance-Kit available upon request. One of the features enabling highly accurate control of outlet pressure Further enabling control precision, high reliability and low maintenance ●● A complete solution, ready to use With integrated pilot pressure regulator, and stainless steel pressure gauges, completely assembled and tested Enabling autonomous operation ●● Simple to install and operate Removable spindle enables simple setting of the required outlet pressure Can be positioned at any angle / orientation For indoor and outdoor installation. Approvals Company certified according to ISO 9001, ISO 22000 and PED 2014/68/EU Module H CE-marked according to PED 2014/68/EU ATEX 2014/34/EU with ignition hazard analysis according to EN 1127-1, DIN EN 13463-1 and ZH1/200 Analysed for Food Safety per HACCP-Analysis Fulfils the requirements of EU Regulations (EC) 1935/2004, and (EC) 2023/2006 Fulfils the requirements of German Food and Feed (LFGB) Law, and is suitable for contact with food gases Operation / Usage Available upon request Ideal for process gas supply where pressure accuracy is required even when inlet pressures and flow rates are varying. Certificates and test reports High flow rates and outlet pressure accuracy are achieved, even when the difference between inlet and outlet pressures is small. Switchover systems / parallel supply systems Other Dome types Customer-specific / customised versions Own-medium controlled, with integrated pilot gas regulator, meaning no separate gas supply is required.
