Dome-loaded Pressure Regulators

PERFORMANCE AND ECONOMIC ADVANTAGES WITT Dome-loaded Pressure Regulators – designed to meet your Value Engineering criteria. › MAXIMUM ACCURACY AND STABILITY IN PRESSURE REGULATION Even when flow rates and temperatures are changing, and when the inlet pressure is falling to within 1 bar (14.5 psi) of the required outlet pressure, WITT dome-loaded pressure regulators maintain control, improving the downstream process performance. › ULTRA-LOW INSTALLATION AND MAINTENANCE REQUIREMENTS WITT domes come fully assembled and tested, own-medium controlled, CE-marked, complete with gauges and...

APPLICATIONS Areas of use, specific requirements, benefits. EXAMPLES: › CRYOGENIC TANK VAPOURISER OUTLETS • A back-up supply to a 24/7 gas generator – the back-up will cut in at precisely the right pressure and will be seamless to the downstream process. This means 100 % availability. Can also be used for peak-shaving. • Purge gases at high flow rates – at just under the downstream relief valve set-pressure • Laser-assist gases – accurately delivered without always needing a 37 barg (536 psi) MAWP tank-rating › CO2 SYSTEMS FOR WELDING GASES • All applications requiring accurate pressure...

FUNCTION A unique design for a unique performance. Dome-loaded pressure regulators are operated with gas pressure. Unlike spring-loaded pressure controllers, the opening force of the valve required for pressure reduction is generated by the pressure of a so-called pilot gas and not by a spring. In the dome-loaded pressure regulator sets from WITT, the gas to be regulated is itself used as the pilot gas („own-medium controlled“). The gas to be regulated is supplied to the dome where it reaches the valve seat. The pilot gas is controlled via a built-in pilot gas regulator and led into the...

PRACTICAL EXAMPLES WITT Dome-loaded Pressure Regulators in industrial plants. › AUTOMATED GAS SUPPLY TO FLAME CUTTING MACHINE The 3 lines for oxygen and propane each go via a dome-loaded pressure regulator. The pilot control gas is regulated via proportional valves controlled by a PLC. Automatic adjustments of the pilot gas pressure regulate the flowrates into the burners, thereby controlling the cutting process. The dome-loaded pressure regulators minimise any variations, and allow for optimal cutting, at a fraction of the price of a fully electronic control system. › NITROGEN SUPPLY...

REPORT WITT Dome Pressure Regulator HD for welding gas mixtures supply. › LEGRIS: „PRESSURE STABILITY IMPROVED OUR CUSTOMER’S WELDING PROCESS“ Legris India offers gas supply solutions, including gas storage and mixing systems. One such project is supplying welding gas mixtures to Indian Railways at Raebareli. CO2 (from cylinders) and Argon (from a cryogenic tank) are supplied into WITT Gas Mixers. Mr Manoj Niraj, Project Manager at Legris, describes the challenge: “We had problems during the commissioning of the system due to not enough CO2 flow to the mixers through the old CO2 regulator...
