Constant Gas Pressure – Even with Extremely Fluctuating Consumption
WITT’s gas engineering specialists have further enhanced their proven dome pressure regulators. The new generation, with optimized pilot pressure regulators, maintains stable working pressure even under widely varying flow rates and inlet pressures. This helps manufacturers improve process reliability and maintain consistent product quality. The upgraded pilot pressure regulators can also be retrofitted into existing systems.
Challenge: Pressure Drop with Increasing Flow Rate
Many conventional pressure regulators experience a drop in outlet pressure when flow rates increase. This can create major problems in industrial settings where multiple machines or workstations draw gas intermittently. If several consumers access the gas supply system at the same time, the available pressure can fall. As a result, production processes may not receive an adequate gas supply, which can disrupt production and affect product quality. WITT dome regulators prevent this effect and now deliver even greater pressure stability through their new design.
Solution: Optimized Control Pressure Regulation for Even Better Performance – Can Also Be Retrofitted
The integrated control pressure regulator has been redesigned to keep outlet pressure stable even under dynamic operating conditions. This gives users reliable, predictable gas pressure. It also helps avoid fluctuations caused by load peaks when consumers are switched on or off. Machines and systems can therefore operate consistently at their intended performance levels.
A key advantage is that existing WITT dome regulators can be upgraded through retrofitting. Customers can improve performance without replacing their systems.
WITT Dome Pressure Regulators – Precise Control at the Highest Level
Dome pressure regulators do not use a spring. Instead, they use the pressure of a control gas. This design enables a highly sensitive and rapid response to pressure changes. WITT has consistently refined this advanced technology over many years.
The result is precise control with a nearly flat pressure curve across the full flow range. The set pressure stays constant despite changes in flow rate, temperature, or inlet pressure, even with a differential of just 1 bar. This supports stable operation without continuous adjustments.
SMART Option: Transparency and Connectivity
WITT dome pressure regulators are also available in a SMART version. This option combines the mechanical precision of the regulators with modern sensor technology and electronics. The systems record and transmit key parameters such as pressure, temperature, and flow for continuous monitoring. As a result, the regulators become an important part of connected production. This improves safety, raises efficiency, and supports predictive maintenance.
Extensive Product Range for the Most Demanding Requirements
WITT offers dome pressure regulators in brass or stainless steel for almost all industrial gases, including oxygen, nitrogen, argon, hydrogen, carbon dioxide, and mixed gases. They are available individually or as fully assembled sets that include control pressure regulators, pressure gauges, and connections. These sets are delivered assembled, tested, and ready to use.
The regulators can be used for inlet pressures up to 40 bar and offer control ranges from 0.5 to 30 bar with maximum flow rates up to 15,000 Nm³/h for N₂ and Kv values up to 30. Special high-pressure models are designed for a maximum operating pressure of 300 bar and working pressures from 0.5 to 60 bar. Threaded and flanged connections from G 3/4” to G 3” / DN100 (DIN or ANSI) are available.
WITT dome pressure regulators comply with relevant standards and regulations, are CE-marked (except 737), and meet the requirements of the Pressure Equipment Directive PED 2014/68/EU. An ATEX 2014/34/EU manufacturer’s declaration is also available upon request.
