Dome-Loaded Pressure Regulators

Product catalog summary

Introduction
WITT Dome-loaded Pressure Regulators are engineered in Germany to enhance performance and value across various applications, offering significant economic advantages.

Specifications
These regulators are available for gases like O2, N2, Ar, He, H2, CH4, and CO2, supporting pressures from 0.5 to 300 barg and flow rates up to 15,000 Nm³/h. They operate in temperatures from -30°C to +50°C and feature threaded and flanged connections.

Performance and Advantages
WITT regulators maintain accuracy and stability despite changing flow rates and temperatures, require minimal installation and maintenance, are CE-marked, and include built-in pilot pressure regulators. They are designed for integration into connected manufacturing systems.

Applications
These regulators are used in cryogenic tank vaporizer outlets, CO2 systems for welding gases, high-pressure industrial gas supplies, and integration into compressors and turbines, ensuring accurate pressure control and high flow rates.

Models
WITT offers models like 737LE/S-HD, 737LE/S, 747LE/S, 767LE/S, and 757LE/S SMART, each tailored for specific performance needs with low maintenance requirements.

Functionality
The dome-loaded pressure regulators use gas pressure for operation, allowing precise pressure regulation without a spring-loaded mechanism.

Practical Examples
Applications include welding gas mixtures supply, automated gas supply to flame cutting machines, nitrogen supply switch-over units, and customized oxygen supply systems in wastewater treatment plants.

Conclusion
WITT Dome-loaded Pressure Regulators offer reliable and efficient pressure control solutions for diverse industrial applications, optimizing processes and reducing costs.

Certifications and Compliance
The systems are certified to ISO 9001, ISO 22000, and PED 2014/68/EU module H, CE-marked under TÜV supervision, and comply with various EU regulations. They are suitable for food applications and meet German Food and Feed Code requirements. Materials in contact with O2 are BAM approved, and regulators for oxygen over 100 barg have been tested for Adiabatic Decompression.

Product Range
Gas Control Equipment: Includes gas mixing systems, metering systems, analysers, leak detection systems, pressure vessels, and customized systems.
Gas Safety Equipment: Features flashback arrestors, non-return valves, quick couplers, safety relief valves, and more.

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....
