Precision Valve Manufacturing

Professional Valve Manufacturer | Integrated Manufacturing

Raw Material Inspection

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 fire hydrant 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 fire hydrant valve components. Critical dimensions, threads and sealing surfaces are strictly controlled to ensure accurate assembly and reliable sealing performance.

Surface Treatment

fire hydrant valve surfaces are professionally shot blasted to remove rust, scale and impurities. by epoxy powder coating, red fire‑retardant painting or hot‑dip galvanizing for long‑term anti‑corrosion performance.

Pressure Testing

Every fire hydrant 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 grooved 90° elbow used for?

To achieve right‑angle turning for fire grooved steel pipelines.

Does it need welding during installation?

No, connect with grooved couplings after steel pipe grooving.

What certifications does this reducer own?

UL Listed and CE certification for fire‑protection application.
