Check valve
This check valve adopts swing, lift and wafer structure, with a simple and compact design, mainly used to automatically prevent medium backflow in pipeline systems. Made of ductile iron, cast steel and stainless steel, it is suitable for conveying media such as water, oil, gas, sewage and mild corrosive fluids. It works automatically relying on medium pressure without external operation, effectively maintaining one-way flow and protecting pumps and other equipment. Applicable to medium and low-pressure working conditions in petroleum, chemical, water treatment, HVAC and urban water supply and drainage, it features stable opening and closing, good sealing performance, low flow resistance and easy installation. Strictly tested for pressure and sealing, it runs reliably with long service life, providing safe and effective anti-backflow protection for various industrial pipeline systems.
Integrated backflow preventer
The Integrated Backflow Preventer is a reduced pressure zone (RPZ) backflow prevention device featuring a one‑piece cast body that integrates two independent check valves and an intermediate relief chamber. It is specifically designed to prevent toxic, hazardous, or highly contaminated media from flowing back into the upstream potable water supply.
Low resistance backflow preventer
The Low Resistance Backflow Preventer is a high-efficiency device designed to prevent reverse flow and protect water supply systems from contamination while minimizing pressure drop. Featuring an optimized flow path and advanced sealing technology, this backflow preventer ensures reliable operation and energy efficiency in potable water, fire protection, and industrial systems. Constructed from stainless steel, bronze, or ductile iron, this valve is durable and corrosion-resistant, suitable for applications requiring high flow rates and low maintenance. Its low resistance design reduces energy consumption, making it an ideal choice for systems where pressure loss is a critical concern.
Copper double check backflow preventer
The Copper Double Check Backflow Preventer is a high-performance, compact device designed to protect potable water systems from backflow contamination. Constructed from durable lead-free copper alloy, it is ideal for residential, commercial, and light industrial applications where water safety and reliability are paramount. This backflow preventer features a double check valve assembly that ensures fail-safe protection against reverse flow, even in low-hazard applications. Its corrosion-resistant copper construction makes it suitable for use with potable water, while its compact design allows for easy installation in tight spaces.
Axial flow non slam check valve
The Axial Flow Non-Slam Check Valve is designed to provide reliable backflow prevention in pipelines where high velocity or sudden flow reversal may occur. Unlike traditional swing check valves, the non-slam feature ensures that the valve’s disc does not "slam" or close abruptly, preventing water hammer and reducing mechanical wear. This valve is particularly suitable for high-velocity applications, making it ideal for industries such as water treatment, power generation, oil and gas, and chemical processing. It offers enhanced durability, reliability, and protection for downstream equipment, while ensuring smooth and controlled fluid flow in critical applications.
Axial nozzle check valve
The Axial Nozzle Check Valve is designed to prevent backflow in high-pressure pipelines, ensuring that fluid or gas only flows in one direction. It is commonly used in industries such as oil and gas, power generation, petrochemical, and water treatment, where controlling fluid direction is crucial for system protection and efficiency. The valve features a streamlined design that minimizes flow resistance, reducing energy consumption and increasing operational efficiency.
2500LB High pressure axial check valve
The 2500LB High Pressure Axial Check Valve is specifically designed to withstand extreme pressures in high-demand applications. Rated for 2500 PSI (2500LB), this valve ensures reliable and secure one-way fluid flow with robust backflow prevention. Its axial flow design and hard sealing surfaces make it an ideal choice for high-pressure pipelines in industries such as oil & gas, power generation, and petrochemical processing. The valve is built to handle harsh operating conditions while ensuring optimal performance and durability.
Tilted disc axial flow check valve
The Tilted Disc Axial Flow Check Valve is engineered to allow fluid flow in one direction while preventing backflow. It uses a tilted disc that is aligned with the flow path, offering minimal resistance, lower pressure drop, and reduced operational noise. The valve is designed to reduce water hammer effects and ensure smooth flow, even under high-pressure conditions, making it ideal for critical industrial systems.
Mute Axial Flow Check Valve
The Mute Axial Flow Check Valve is a specialized valve designed to provide superior flow control and minimize the risk of water hammer, noise, and vibration in fluid systems. Unlike conventional check valves, the mute axial flow check valve incorporates a streamlined valve disc design and advanced internal structure to ensure smooth operation while significantly reducing the potential for water hammer, which is a common issue in many industrial piping systems. This valve is particularly suitable for applications where noise reduction and protection against system surges are essential.
Vertical forged steel check valve
This vertical forged steel check valve adopts an integral forged steel body and vertical structure, which automatically opens and closes by medium pressure to effectively prevent backflow. It is specially designed for small-bore high-temperature and high-pressure working conditions.
