Engineered for high-cycle applications, our comprehensive range of pneumatic actuators—from compact rack-and-pinion to heavy-duty scotch yoke and linear designs—delivers precise torque and rapid response.
Featuring IP67/IP68 weatherproof enclosures and smart position control, these electric actuators provide stable, maintenance-free automation for both quarter-turn and multi-turn pipeline systems.
Enhance your valve automation with our NAMUR-standard limit switch boxes, smart positioners, and manual overrides. Engineered to provide accurate status feedback and reliable emergency control.
Delivering high-thrust push/pull force with smart positioning options, our electric linear actuators ensure precise automation for control valves and dampers.
Driven by compressed air, our pneumatic actuated valves deliver rapid response times and reliable fail-safe (spring-return) operation. Inherently safe for hazardous environments, they are the proven choice for high-cycle isolation and emergency shutdown applications.
Equipped with advanced motor drives, our electric actuated valves provide pinpoint modulating control and seamless PLC integration. Operating independently of compressed air, they offer steady, shock-free fluid regulation for complex process loops and remote locations.
Compact yet powerful, our mini motorized valves are the ideal automated solution for tight spaces and HVAC applications requiring durable, low-energy flow control.
Engineered with a streamlined body for high-flow and high-cycle applications, our angle seat valves efficiently handle steam and viscous fluids with minimal pressure drop.
Built for demanding industrial environments, these heavy-duty pneumatically operated valves provide reliable, zero-leakage control. Their robust flanged design makes them the ideal solution for handling your toughest corrosive and abrasive media.
Ensure highly accurate valve modulation. Our smart electro-pneumatic positioners offer rapid auto-calibration and seamless integration with standard 4-20mA control loops.
Hearken controls and tests each range product according to requirements， to ensure quality
Hearken electric actuators have a variety of product models to meet your needs in different scenarios; At the same time, we can also customize different voltage specifications (such as AC220V, DC24V, etc.) and different control methods (such as switch type, regulator type) to flexibly meet the needs of customers for various working conditions.
Hearken pneumatic actuators need to pass a series of strict inspections from production to shipment. The inspection of spare parts mainly focuses on the following items: the roughness of the inner wall of the cylinder and the straightness of the cylinder barrel. Piston diameter dimensions, seals; Spring elasticity testing and appearance check; Each component needs to undergo material composition analysis. After the product is assembled, we will inspect the aspects of component connection, appearance and action response. Only when the product meet the ISO9001 requirement, our pneumatic actuators will go to the next step or arrange the delivery.
Hearken electric valves are of stable and reliable quality, and the entire production process is strictly controlled. For each set of products, we will conduct appearance inspection and sealing test. Meanwhile, for valves, we will also carry out raw material inspection. Among them, the motor, deceleration mechanism and control circuit board are the most important in our test list. We adhere to high standards, strictly implement quality inspection requirements in every step, and comprehensively guarantee the performance of valves.
Hearken pneumatic valves implement a set of standard quality control systems before delivery, such as raw material testing, appearance inspection and sealing performance testing for the valves; Meanwhile, production process control is implemented for the cylinders, springs and pistons of pneumatic actuators; After the assembly is completed, we will test the opening and closing action of the product and the overall leakage amount; Only products that pass all the tests and meet the standards，the products will be delivered to customers through anti-damage packaging.
Hearken provides complete actuator control packages for our global partners. Beyond our core valve actuators, we supply a full range of pneumatic control accessories. Limit switch boxes provide accurate position feedback, while pneumatic positioners ensure precise flow control. Manual overrides allow dependable emergency operation during air loss, and solenoid valves offer fast response for high-cycle lines. We simplify your sourcing by delivering integrated actuation solutions with complete technical support.
