Valve Type and Actuator Torque Selection

Valve Type and Actuator Torque Selection

Why Valve and Actuator Matching Matters In an automated industrial valve system, the valve and electric actuator should be regarded as a complete mechanical and control unit rather than two independent products. The valve determines the required movement, operating load, sealing characteristics, and process function, while the actuator provides the mechanical force and control capability needed to...

How Check Valves Stop Reverse Flow

How Check Valves Stop Reverse Flow

The Basic Principle Behind Check Valves A check valve is one of the simplest yet most important components in a fluid-control system. Unlike a gate valve, globe valve, or motor-operated valve, a conventional check valve normally does not require an external actuator to initiate its opening or closing movement. Its operation is driven primarily by the pressure difference and flow behavior of the process...

Research on the Interchangeability of Wedge Gate Valves

Research on the Interchangeability of Wedge Gate Valves

Abstract: Widely used in petroleum, chemical, and nuclear power applications, wedge gate valves suffer from poor interchangeability, low efficiency, and difficult maintenance due to their custom-matched assembly process. This paper examines the manufacturing processes for valve bodies and gate wedges, identifies the primary factors affecting interchangeability, and puts forward corresponding optimization...

Improving the Manufacturing Process for High-Temperature, Wear-Resistant Gate Valves

Improving the Manufacturing Process for High-Temperature, Wear-Resistant Gate Valves

Abstract: Catalytic reactions typically occur under high-temperature, high-pressure, and high-velocity environments. Valves used in fluid catalytic cracking (FCC) units are prone to erosion from the process medium. Several factors significantly shorten the service life of gate valves, including the degradation of metal mechanical properties at high temperatures, rapid wear caused by catalyst...
