Hydraulic Actuated Valve

Except for automatic valves like check valves, all valves requiring powered operation can be designed as electric actuated valves. Their core feature is remote control via electrical signals (such as 4-20mA, 0-10V, or Modbus), making them suitable for fluid systems needing high-precision regulation or intelligent management. Applicable industry standards include IEC 60534 (Industrial Process Control Valve Standards), ISO 5210/ISO 5211 (Actuator Mounting Interface Specifications), and ATEX/IECEx (Explosion-proof Certification for hazardous areas). The electric actuator brand can be selected by the customer or chosen by our company. If the customer provides working pressure and specific media details, we will calculate torque and select parameters accordingly; otherwise, sizing is based on nominal pressure.

Except for automatic valves like check valves, all valves requiring powered operation can be designed as pneumatic actuated valves. Pneumatic valves are automated valves driven by compressed air actuators, widely used in chemical, petroleum, pharmaceutical, and food processing industries for fluid control systems. Their key advantages are fast response, reliability, and adaptability to harsh environments, especially suitable for explosion-proof, high-frequency operation, or remote control scenarios. Pneumatic actuator brands can be customer-specified or selected by our company. If the customer provides working pressure and media details, we calculate thrust and select parameters accordingly; otherwise, sizing is based on nominal pressure.

The hydraulic actuator uses hydraulic oil as the power source to drive the valve. It provides large output torque and can be precisely adjusted as required. The transmission is smoother, with no impact phenomenon, but it requires support from an external hydraulic system.
