Corrosion-Shielded Stainless Construction: Molded entirely from premium-grade stainless steel, ensuring exceptional resistance against aggressive media and harsh fluid environments.

• Self-Sustaining Hydraulic Drive: Utilizes line pressure to drive an internal pilot mechanism, eliminating the need for external electric or pneumatic power.

• Dual-Channel Differential Sensing: Integrated dual pressure-sampling ports continuously measure upstream and downstream differentials to deliver precision flow regulation.

• Motor Protection & Surge Mitigation: Dynamically restricts maximum flow rates to prevent pump motor overload while utilizing a slow-closing mechanism to dampen severe water hammer.

• Streamlined Field Calibration: Outfitted with twin exterior needle valves to allow safe, intuitive fine-tuning during system setup and routine servicing.

• Low-Friction Diaphragm Actuation: A heavy-duty, resilient diaphragm guarantees smooth, low-wear valve travel and reliable long-term performance.

• Standardized Flanged Coupling: Designed to international flange specifications for fast alignment, leak-tight sealing, and easy inline removal.

Primary Application Areas

• Parallel pump discharge headers in booster stations

• Municipal water transmission and distribution mains

• High-rise residential and commercial pressure-boosting networks

• Industrial cooling towers and process water loops

• Water treatment plant headers and HVAC central air-conditioning circuits

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.
