Established In 1991
Precision Valve Category
Our core product portfolio covers brass globe valves, resilient seated gate valves, ball valves, butterfly valves, grooved butterfly valves, Y-type strainers, magnetic locking gate valves and brass air release valves.
Control Valves
Control valves are professionally designed for precise adjustment of pipeline flow, pressure and temperature. They automatically adjust medium parameters according to working conditions to stabilize system operation and adapt to automatic pipe network control systems. Our valves feature high regulation accuracy, sensitive response, stable operation, good sealing, corrosion and wear resistance, suitable for various precision industrial fluid pipeline conditions.
Gate Valves
Gate valves are universal cut-off valves for pipelines, controlling medium on-off through gate lifting. They feature low flow resistance, reliable sealing, stable opening and closing and no flow direction limitation, applicable for full opening and full closing rather than flow regulation. Our gate valves are well-made, pressure and temperature resistant, tightly sealed and durable, suitable for petrochemical, municipal, power and other industrial pipe networks.
Butterfly Valves
Butterfly valves are lightweight and high-efficiency pipeline control valves, realizing medium cut-off and regulation by disc rotation. They have compact structure, rapid opening and closing, small size, light weight and convenient operation, with both cut-off and throttling functions. Our butterfly valves have excellent sealing, wear and corrosion resistance, small operating torque and stable operation, widely used in HVAC, water supply, environmental protection and chemical pipeline systems.
Check Valves
Check valves are self-operated valves that realize one-way flow by medium pressure and automatically prevent medium backflow, avoiding reverse flow, equipment reversal and water hammer impact to ensure stable one-way operation of pipeline systems. Our check valves have sensitive action, tight sealing, low flow resistance, good scour resistance and stable performance, widely used in water supply, chemical, power and heating pipeline systems.
Ball Valves
Ball valves are high-performance pipeline cut-off valves, achieving rapid medium on-off through ball rotation. They feature tight sealing, fast switching, minimal flow resistance, easy operation and wide medium adaptability for cut-off and regulation working conditions. Our ball valves have high precision, excellent corrosion, pressure and wear resistance and stable performance, suitable for harsh working conditions such as petrochemical, power, gas and industrial fluid pipelines.
Air Release Valves
Air release valves are critical automatic protection components for pressurized fluid pipelines. They continuously vent trapped air accumulated inside piping during system filling, operation and draining, eliminating air pockets that cause water hammer, flow restriction, corrosion and noisy operation. When negative pressure forms, they also admit air to prevent pipeline collapse. Widely installed on high points of chilled water, water transmission, fire protection and process fluid networks to stabilize flow and safeguard pipeline integrity.
Globe Valves
Globe valves are widely used for pipeline cut-off and throttling. They control medium on-off and flow regulation through disc lifting, featuring excellent sealing, reliable operation, accurate throttling and controllable flow resistance. With compact structure, high temperature and pressure resistance and scour resistance, our globe valves are long-lasting and suitable for petrochemical, power, heating, water supply and other industrial and civil pipelines.
Balancing Valves
Balancing valves are mainly used for hydraulic balance adjustment of pipe networks. They accurately control branch flow and pressure difference, balance the hydraulic working conditions of the entire pipe network, avoid uneven temperature, pressure imbalance and energy waste, and ensure efficient and stable system operation. Our balancing valves feature precise regulation, reliable locking, pressure and corrosion resistance and convenient operation, suitable for HVAC, heating and water supply pipe networks.
Fire Protection Valves
Fire protection valves are core safety components in fire suppression piping systems, designed to control, isolate and regulate the flow of fire-fighting water. Available in deluge, butterfly, check and gate types, these UL/FM certified valves reliably activate or shut off fluid pathways under emergency conditions. They maintain system pressure, enable sectional isolation for maintenance, and ensure rapid water delivery to sprinkler or deluge systems when fire occurs, widely deployed in pump rooms, riser networks and industrial fire protection loops.
Backflow Preventers
Backflow preventers are special safety valve equipment for water supply and drainage pipeline systems. They strictly prevent medium backflow and avoid water source pollution caused by the reflux of sewage and pollutants in pipe networks, ensuring the cleanliness of pipeline medium and system safety. Our backflow preventers feature precise structure, reliable sealing, sensitive opening and closing, stable anti-backflow performance, corrosion resistance and durability. They are widely used in municipal water supply, building water supply and drainage, industrial pipe networks and other scenarios, serving as core supporting equipment for anti-pollution and safety protection of pipeline systems.
Filter & Strainers
Filters and strainers are essential inline purification devices for fluid piping systems. They trap solid particles, sediment and debris carried in water or process fluid, preventing impurities from clogging precision valves, actuators, meters and heat exchangers. Ranging from coarse basket strainers to fine mesh filters, they can be cleaned without full system shutdown in most cases. They protect downstream equipment, reduce wear and extend service life, applied in chilled water, municipal transmission, wastewater and process utility pipelines.
Pipe Fittings & Accessories
Pipe fittings and accessories form the complete connection network for fluid piping. This portfolio includes flanges, elbows, tees, reducers, expansion joints, gaskets, hangers and isolation components. They connect pipe segments, change flow direction, adjust pipe diameter, absorb thermal expansion and vibration, and provide sealing and structural support. Standardized for hydronic, fire, water and process systems, they guarantee leak-tight joints, stable pipeline operation and convenient assembly or disassembly for industrial and utility corridor projects.
