Description Vendor

The DRX15 High Pressure Dome Regulators are specialized pressure control solutions designed for use with hydrogen at high pressure and across a wide temperature range. These regulators are configurable and provide fully tested pressure control solutions, making them ideal for applications requiring precise and reliable performance. Key features include a spring-loaded pilot regulator for easy adjustment, a dynamic pilot system that ensures stable outlet pressures even with rapid inlet pressure changes, configurable connection ports for easy integration, a fully balanced valve mechanism for long service life and accurate pressure control, and proprietary sealing technology that ensures leak-tight construction in hydrogen service. They are particularly suited for H2 systems and trailer decanting applications, especially where high flow is required even at low trailer pressure. The regulators are constructed from stainless steel 316L, with PCTFE, HNBR, and PEEK seal materials, and are available in various configurations to meet specific application needs.

Use Cases

  • H2 Systems (in conjunction with our Slam Shut Valves for full pressure safety on flammable gas systems)
  • Trailer Decanting (especially where high flow is required, even at low trailer pressure)

Capabilities

  • No client engineering required to set-up - all functions delivered in one assembly
  • Dynamic Piloting offers improved delivery pressure accuracy
  • Spring loaded pilot can be easily adjusted or locked at a set pressure
  • Max Inlet Pressure (bar) 780
  • Max Outlet Pressure (bar) 250
CIRCOR International, Inc CIRCOR International is a global leader in mission-critical flow control technology, providing specialized high-pressure solutions through its renowned Hale Hamilton brand. With more than 70 years of engineering expertise, the company offers a comprehensive portfolio of hydrogen-ready components, including isolation valves, pressure regulators, and safety-critical protection systems designed for pressures up to 700 bar. CIRCOR distinguishes itself by delivering fully integrated hydrogen system panels and custom skid solutions, such as trailer fill cabinets and automated manifold systems, which are essential for refueling infrastructure and gas transport. Their commitment to safety and reliability is backed by compliance with international certifications like the European Transportable Pressure Equipment Directive, making them a preferred partner for industrial, mobility, and energy transition applications.
