By consolidating their supply chain with a trusted valve manufacturer, businesses can reduce lead times, simplify quality assurance, and achieve better pricing through volume commitments.

Ball valves represent a core product line for this industrial valve manufacturer, and Hongyi produces both floating and trunnion-mounted varieties to suit different operating conditions. Floating ball valves are ideal for low-to-medium pressure applications where the ball is held in place by the seat rings, providing a bubble-tight shutoff. Trunnion-mounted ball valves, on the other hand, feature a fixed ball supported by bearings, making them suitable for high-pressure and large-diameter pipelines common in oil and gas transmission. All ball valves undergo rigorous shell and seat leakage tests in accordance with API 598 and ISO 5208 standards. Customers can choose from materials such as WCB, LCB, CF8M, duplex stainless steel, and exotic alloys for corrosive environments. Actuation options include manual, gear-operated, pneumatic, electric, and hydraulic, giving end users maximum flexibility. Whether it is a simple isolation valve for a water treatment plant or a critical emergency shutdown valve for a refinery, Hongyi's ball valves deliver consistent performance.

As one of the leading valve suppliers for the energy sector, their ball valves are widely specified by EPC contractors and engineering firms around the globe.

Gate valves remain a staple in industrial piping systems, and Wenzhou Hongyi Valve excels as one of the premier gate valve manufacturers in the industry. Their product range includes both rising stem and non-rising stem configurations, each engineered for specific installation requirements. Rising stem gate valves provide a visual indication of the valve position, making them ideal for above-ground applications where operators need to confirm open or closed status at a glance. Non-rising stem designs are preferred for underground or space-constrained installations where the stem cannot extend upward. All gate valves feature a full-port design that minimizes pressure drop and allows pigging in pipeline systems. The company manufactures gate valves in accordance with API 600, API 602, and BS 1414 standards, with pressure ratings from Class 150 to Class 2500. Body materials range from carbon steel for general service to stainless steel and nickel alloys for corrosive or high-temperature environments. Every unit is tested for shell integrity, seat leakage, and backseat sealing to ensure zero fugitive emissions. With trims available in 13Cr, F6a, Stellite, and Inconel, these valves can withstand erosive media in steam, oil, and chemical services. Hongyi's gate valves are trusted by refineries, petrochemical plants, and power generation facilities worldwide for their robust construction and long service life.

Check valves play a critical role in preventing backflow and protecting rotating equipment, and Hongyi offers both swing and lift check designs to cover a broad spectrum of applications. Swing check valves feature a hinged disc that opens with forward flow and closes under reverse flow, making them suitable for horizontal or vertical upward flow installations. Lift check valves, by contrast, use a spring-loaded or gravity-operated disc that lifts vertically, providing tighter sealing for pulsating flows or small-diameter lines. Both types are available in wafer, lug, and flanged end connections to match existing piping layouts. The company’s check valves are designed in accordance with API 6D and ASME B16.34, with pressure classes ranging from Class 150 to Class 2500. Materials include carbon steel, stainless steel, duplex, and super-duplex grades for sour gas and offshore environments. Each valve is hydrostatically tested and seat leakage tested to ensure zero reverse flow at rated pressure. For critical services such as compressor discharge or pump recirculation lines, Hongyi can supply silent or nozzle-type check valves that minimize water hammer and vibration. As preferred valve suppliers for the oil and gas industry, their check valves provide the reliability and safety that high-stakes applications demand. Engineers often specify Hongyi check valves for pipelines, refineries, and water injection systems where uninterrupted flow and equipment protection are paramount.

Beyond standard valve types, Wenzhou Hongyi Valve also manufactures a range of specialty products that address unique process requirements. Their control valve lineup includes globe-style and angle-style control valves equipped with pneumatic or electric positioners for precise flow modulation. These control valves are designed to handle high pressure drops, cavitation, and erosive media, with trim options such as cage-guided, multi-stage, and anti-cavitation designs. The company also produces butterfly valves in concentric and double-offset configurations, making them one of the more versatile butterfly valve manufacturers serving the water and wastewater sector. For high-temperature applications, they offer bellow-sealed globe valves and gate valves that prevent stem leakage in thermal cycles. Other specialty items include knife gate valves for slurry handling, axial flow check valves for gas compression, and three-way diverter valves for process switching.
