Sunfair Fluid Control Co., Ltd

Who We Are

We are an industry-integrated enterprise specializing in the export of high-performance industrial valves, with a core focus on butterfly valves.Our dedicated manufacturing base is strategically located in Wenzhou, Zhejiang Province - the renowned "Pump and Valve Town" of China.This geographic foundation allows us to combine factory-floor precision with global commercial reach, operating as a seamless manufacturing-trading synergy.

Our Manufacturing Base

Rooted in the heart of Wenzhou's industrial cluster, our production facilities benefit from a complete local supply chain ecosystem.Our workshops are equipped with advanced CNC machining centers, automated coating lines, and comprehensive testing benches.This vertical integration ensures rigorous quality control, from raw material melting and casting to final assembly and pressure testing, guaranteeing that every valve leaving our factory meets stringent international standards.

Design & Engineering Advantages

Innovation drives our engineering philosophy.Our in-house technical team collaborates closely with factory engineers to continuously optimize valve design for improved flow efficiency, sealing performance, and operational longevity.We specialize in:

Structural optimization for reduced torque and enhanced cycle life

Customized material pairing (from ductile iron and CF8/CF8M stainless steel to specialized alloys) to suit diverse media conditions

Modular actuation interfaces for hassle-free mounting of pneumatic, electric, and hydraulic actuators

Our design capability extends beyond standardization - we actively engage in co-development with clients, offering tailored solutions for niche applications in water treatment, chemical processing, marine engineering, and oil & gas sectors.

Resource Integration Capabilities

As a manufacturing-integrated supplier, we excel in consolidating and optimizing resources across the entire value chain:

Supply Chain Synergy:Leveraging Wenzhou's mature industrial ecosystem, we source high-quality components (castings, stems, seals, coatings) at competitive costs while ensuring consistency and traceability.

Production Flexibility:We intelligently allocate workloads across multiple production lines to accommodate both large-volume standard orders and small-batch customized projects with equally efficient turnaround.

Cost-Efficiency:By integrating material procurement, precision machining, assembly, and logistics under one coordinated system, we eliminate redundant intermediaries and pass the value directly to our customers.

Core Product Portfolio

Our flagship butterfly valve line covers:Wafer, Lug, and Flanged types

Resilient-seated and PTFE/RTFE-lined high-performance types

Triple-offset metal-sealed valves for high-temperature and high-corrosion duties

Manual (lever/gear), pneumatic, and electric actuated solutions

Quality Assurance

We implement a closed-loop quality management system, with certifications including ISO 9001, CE (PED), API 609, and AWWA C504.Every production stage - from incoming material inspection to hydrostatic and pneumatic testing - is documented and traceable.
