Precision Valve Manufacturing

Professional Valve Manufacturer | Integrated Manufacturing

Raw Material

We select high-quality raw materials according to product specifications and international standards. All incoming materials are carefully inspected to ensure chemical composition, mechanical properties and traceability.

Forging & Casting

Advanced forging and casting processes are used to produce strong and reliable valve bodies and components. Strict process control ensures uniform structure, dimensional accuracy and excellent mechanical performance.

CNC Machining

Our CNC machining equipment provides precise and consistent processing of valve components. Critical dimensions, threads and sealing surfaces are strictly controlled to ensure accurate assembly and reliable sealing performance.

Shot Blasting & Coating

Valve surfaces are professionally shot blasted to remove rust, scale and impurities. Protective coatings are then applied according to customer requirements, providing excellent corrosion resistance and a durable surface finish.

Pressure Testing

Every valve undergoes strict pressure testing before shipment. Body and seat tests are performed according to applicable standards and customer specifications to verify pressure resistance and sealing reliability.

Quality Inspection

Our quality control team conducts comprehensive inspections throughout the production process. Finished valves are checked for dimensions, appearance, materials, pressure performance and overall quality before final approval and shipment.

What is an electric gear actuator used for?

An electric gear actuator is used to remotely operate valves by converting electrical power into mechanical torque. It is commonly used for opening, closing, or positioning industrial and water-system valves.

Which types of valves can be equipped with an electric actuator?

Electric actuators can be used with various quarter-turn and multi-turn valves, including butterfly valves, ball valves, gate valves, globe valves, and other compatible valve types.

What power supply options are available?

Common power supply options include 24V, 110V, 220V, and 380V AC/DC configurations, depending on the actuator model and project requirements.

Is manual operation available during a power failure?

Many electric actuators are equipped with a manual override mechanism, allowing the valve to be operated manually when electrical power is unavailable.
