Specifying Regulators for Wellhead Control Systems in Harsh Environments
Wellhead control systems are critical safety and automation systems used in oil and gas extraction to monitor, control, and shut down well operations—both onshore and offshore. They manage the flow of hydrocarbons from the wellhead and ensure safe operation during drilling, production, or intervention. In these demanding environments, selecting the right wellhead control regulator is essential to ensuring reliable performance. Harsh environments often involve temperature extremes, corrosive media, and high-pressure demands. Regulators must be robust enough to deliver consistent oil and gas pressure control while resisting degradation over time. Material choice is key—316 stainless steel or Inconel are often preferred for their corrosion resistance and mechanical strength. Equally important is regulator stability. Pressure droop, hysteresis, and setpoint drift can all compromise wellhead safety and control. High-performance regulators with tightly controlled flow curves and minimal internal leakage are essential for maintaining system integrity. At Pressure Tech, our regulators for wellhead control are designed with these challenges in mind—offering rugged construction, low maintenance, and reliable performance in offshore, desert, and arctic conditions. Optional features such as low-temperature elastomers, NACE compliance, and panel-mount configurations further enhance adaptability. For engineers and operators in the oil and gas sector, specifying the correct pressure regulator is not just a design decision—it’s a safeguard for uptime, safety, and operational excellence.

How Pressure Regulators Improve Safety in Hydrogen Refuelling Stations
Hydrogen refuelling stations (HRS) are essential to supporting the transition to zero-emission transport. With hydrogen stored at pressures up to 700 bar, effective pressure regulation is critical to ensure safe and stable operation. Let’s look at the role they play. Pressure regulators control the pressure of hydrogen from high-pressure storage to vehicle systems, maintaining consistent output pressure while protecting downstream components. The control element is critical because without it, there’s a risk of over-pressurisation, and even equipment failure. At Pressure Tech, we have a range of regulators designed specifically for hydrogen service. Body and component material selection are of utmost importance to ensure strength, longevity, and resistance to hydrogen embrittlement. Hydrogen embrittlement is a form of material degradation where metals become brittle and crack due to the absorption and diffusion of hydrogen atoms into the metal—especially under stress. Additional safety measures, such as integrated filters and optional venting, help prevent contamination damage and provide protection in overpressure scenarios. Positive Material Identification (PMI) testing and full material traceability further enhance quality assurance. In line with the growing hydrogen infrastructure, the demand for robust, reliable pressure control is also increasing. Selecting the right pressure regulator doesn’t just optimise performance—it protects people, equipment, and long-term investment. For OEMs and station developers, high-quality regulation is a fundamental part of building a safe and efficient hydrogen refuelling network.
