Dome-loaded Pressure Regulators

PERFORMANCE AND ECONOMIC ADVANTAGES WITT Dome-loaded Pressure Regulators – designed to meet your Value Engineering criteria. Areas of use, specific requirements, benefits. › 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,...

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 pressure chamber....

PRACTICAL EXAMPLES WITT Dome-loaded Pressure Regulators in industrial plants. 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...
