Zhejiang Bigtork Valve Automation Co., Ltd. is one of the leading manufacturers and suppliers of single acting hydraulic actuator in China. As we have world-leading production equipment and strong manufacturing capabilities, we warmly welcome you to buy customized single acting hydraulic actuator from our factory.
Products Introduction
A single-acting hydraulic actuator is a drive device in which hydraulic fluid is supplied to only one side of the piston, while the other side is provided with a return force by a spring. When hydraulic pressure is applied, the valve opens or closes; when the pressure is released, the spring automatically returns the actuator to its initial position, thereby completing the opposite motion. This product features a simple structure and reliable operation, making it particularly suitable for applications with high safety requirements. In emergency situations (such as power outages or system pressure loss), its spring-return function enables rapid shutdown or opening, ensuring the intrinsic safety of the system. As a result, single-acting hydraulic actuators are widely used in industrial sectors such as petroleum, chemical, and power generation that require emergency shutdown or safety protection.
