RH-25100 electric control valve is manufactured by Cryogenic Valve Research, Inc., a leading industrial valve manufacturer that has served the power industry for over 70 years. Its reliability and accuracy make it suitable for critical applications where pressure and temperature control are needed. The RH-25100 is part of a family of high-pressure valves that are designed to operate in a range of fluid properties from laminar flow to turbulent flow. It is also available in a range of sizes for a variety of applications, such as subsea, surface and high temperature valves.

The RH-25100 can be used in liquefied natural gas (LNG) processing, pipeline transmission, controllers and actuators. It is a pressure actuated valve which can be used to control supply pressure, distribution pressure and bypass pressure. The selection of the actuator is based on specific system requirements, while the actuation can be done by either electric or pneumatic control. The electric actuation is done through a control unit or a PLC, while the pneumatic actuation is done through a manifold system.

The RH-25100 features an advanced design which enables an accurate and repeatable closing and opening force for a wide range of pressure ranges. It is designed with a high degree of safety in mind, as it is provided with an adjustable safety limit setting in order to ensure the valve does not perform beyond the desired limit. The valve is provided with a full range of diagnostic features, such as for temperature, pressure and flow rate, which can be used to monitor the performance of the valve.

When it comes to its working principle, the RH-25100 utilizes a differential pressure actuation principle, which helps to maintain an extremely tight control of pressure and temperature. The valve is provided with two supply chambers, one at the higher pressure side and another at the lower pressure side. The sealing of both of the chambers is done by a special seating disk and a seat ring. The valve utilizes a combination of the differential pressure actuation and a pilot relief valve system in order to accurately monitor and control pressure. When the pressure differential between the two chambers is equal, the valve is then closed, providing tight regulation of pressure.

In conclusion, the RH-25100 is a reliable and accurate electric control valve that is suitable for a variety of applications. Its advanced design ensures accurate and repeatable closing and opening forces, while providing a wide range of diagnostic features for monitoring the valve performance. The valve working principle utilizes a differential pressure actuation principle for precise pressure and temperature control.
