WITT sets new standard among dome-loaded pressure regulators

04.09.2014

Although the dome-loaded pressure regulators from WITT-Gasetechnik are already known for being enormously pressure-stable, the German manufacturer is setting an even higher benchmark with the new version of its ready-to-use dome-loaded pressure regulator sets, thereby consolidating its position as a technological leader.

Thanks to its dome-loaded pressure regulators for line installation, WITT is regarded as one of the world's leading manufacturers of high-quality gas pressure control technology. With the imperative being a precise and, above all, stable working pressure, WITT has improved the tolerances once again. "The pressure consistency of our dome-loaded pressure regulators is better than ever," states Product Manager Andreas Heyer. A design modification to the newly integrated control pressure regulator ensures an almost complete compensation of supply pressure and outlet fluctuations. As a result, users can rely on constant conditions in the gas supply at any time. According to Heyer: "The control behaviour is extremely stable, even with extremely high or low flow rates within the performance range. That means WITT dome-loaded pressure regulators ensure the highest process reliability."

In contrast to spring-loaded pressure regulators, dome-loaded pressure regulators are operated by gas pressure. This so-called control gas is monitored via a separate control pressure regulator. Two major advantages of WITT dome-loaded pressure controller sets are their ease-of-use and flexibility. The control pressure regulator can be used to increase or reduce the gas pressure at any time, as soon as another working pressure is required.

"With the latest models, the control module is now fully integrated into the housing," declares Heyer. "That makes the system more compact, robust and maintenance friendly." New materials for seals, diaphragm and threaded joints have also increased the weather-resistance for outdoor installations, allowing for a temperature range of -30 to +50°C (-22 to 122°F).

WITT supplies its dome-loaded pressure regulator sets as fully assembled units complete with control pressure regulators and pressure gauges. There’s no need for any separate gas supply for pressure control – the pilot system works with the gas in the line that is regulated. WITT offers a self-contained, safe and ultimately cost-effective solution that also avoids releasing control gas into the environment.

The new sets are already available with dome-loaded pressure regulators of types 737, 747, 757, 767 and 772. All casings are made of brass, but are also available in stainless steel (with the exception of the 767). High flow rates to Kv value 30 (Cv value 34.8), inlet pressures to 300 bar (4350 psi) and working pressures from 500 mbar to 45 bar (7.25 to 650 psi) can be attained with the manufacturer's product portfolio.

The precise pressure control, high pressure consistency and design concept with control pressure regulator, which enables working pressure adjustments during operation, have long made WITT fittings the choice for users who require a reliable gas supply for their production processes.
