Features

1.Flat-bottom Valve Seat：

It overcomes the problem of poor sealing in traditional gate valves caused by foreign objects-such as stones, welding rod ends, welding slag, cement, etc. being trapped in the grooves after the flushing pipeline installation. The resilient seated gate valve adopts a flat-bottom design consistent with the pipeline, which is not prone to debris accumulation, ensures smoother fluid flow, and extends the service life of the valve.

2.Full Rubber Coating on Gate Plate

The gate plate is fully rubber-coated both internally and externally. The first-class domestic rubber vulcanization technology ensures the precise dimensions of the gate plate after vulcanization, resulting in firm bonding between the gate plate and rubber that is not easy to fall off, along with excellent elasticity.

3.Corrosion Resistance

The ductile iron gate valve is coated with epoxy resin powder, which can prevent valve body corrosion and rusting. It meets the national hygienic standard for drinking water and is also suitable for sewage treatment applications.

4.Multi-channel O-ring Design：

This design reduces friction resistance during opening and closing, significantly minimizing water leakage. It can also be upgraded to an online maintenance type (self-sealing type) for sealing ring and packing replacement according to customer requirements.

5.Precision Cast Valve Body

The valve body is manufactured via precision casting. Its accurate geometric dimensions ensure the valve's sealing performance without the need for internal machining.

6.Lightweight

The valve body is integrally precision-cast, featuring light weight, high strength, and easy installation and maintenance.

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.
