Regulators

Regulators are self-contained devices that use energy from the process flow to regulate pressure or temperature. As a result, unlike control valves, regulators do not require an actuator in order to operate and control.

Pressure regulators are either direct operating type or pilot operated. The direct operating pressure regulator uses a single flow path to counter fluid pressure with an opposing spring force to maintain pressure. A pilot operated regulator, on the other hand, uses two flow paths – one path for the pilot and one for the main regulator body. Self-acting temperature regulators are self-powered, without the need for electricity or compressed air.

The temperature regulator is comprised of a control valve, a sensor, capillary tubing and an actuator. Expansion of contraction of a temperature sensitive fluid in the sensor and capillary expands with a rise in temperature. The force created by this expansion is transferred via the capillary to the actuator, thereby opening or closing the control valve, and in turn controlling the flow of fluid through the control valve. Pilot-operated regulators are more accurate and offer higher capacities than standard direct-operated regulators.

CIRCOR Energy offers both temperature and pressure regulators. Our pressure regulators include premium models with excellent technical specifications for industrial pressure regulating application to reliable, cost effective solutions for district heating, steam distribution and commercial building use.

CIRCOR Energy regulators, available in both direct operated and pilot operated versions, are known for their universal adaptability, accuracy of regulation and dependable performance.
