As a major manufacturer of dome pressure regulators, WITT now offers its full range of products not only in brass, but in stainless steel too. This choice allows users to reduce the pressure of nearly all industrial, aggressive and corrosive gases, the company explains.
The regulators, which control line pressure via a gas cushion, are intended for installation in gas pipelines or production facilities, such as in chemical and environmental engineering, metal and glass processing and food production.
Compared to conventional pressure regulators, dome pressure regulators are characterized by an extremely stable control behavior, even if the extraction quantity varies, there are extremely high or low flow rates, or if fluctuations in the gas inlet occur. The operator consistently receives a constant working pressure for a high degree of process stability.
For applications that involve aggressive and corrosive gases, WITT uses a special combination of materials. The housings are made of high-quality stainless steel 1.4404 (AISI 316L), which is characterized by high acidity and corrosion resistance. The very resistant FPM is used as sealing and membrane material. The manufacturer offers customized, special solutions upon request.
Dome pressure regulators allow the smallest differences of less than one bar to be just as quickly and precisely regulated as very large ones. A two-stage pressure regulation is no longer necessary in most of the cases.
The low-maintenance regulators are suitable for up to 300 bar (4351 psi) of system pressure, supply line pressures that are adjustable down to 0.1 bar (1,45 psi), and handle a gas flow of several tens of thousands cubic feet per hour. All models are available as a complete, tested set, including pilot pressure regulator, pressure gauges and fittings.
