Check valves are vital components in industrial piping systems, preventing backflow and ensuring fluid moves in a single direction. At Lianhe Valve (Wenzhou Lianhe Valve Fitting Co., Ltd.), we manufacture high-quality stainless steel check valves designed for durability, precision, and safety. Each valve meets international standards, offering dependable performance in demanding environments where corrosion resistance and reliability are essential.
We provide a wide range of industrial check valves to meet different pressure and flow requirements. Each type is engineered for specific operating conditions, ensuring optimal system performance and efficiency.
| Type | Function | Typical Applications |
|---|---|---|
| Swing Check Valves | Feature a swinging disc that allows forward flow and closes automatically to prevent reverse flow. | Ideal for low-pressure systems and large-diameter pipelines. |
| Lift Check Valves | Use a piston or ball mechanism that lifts under forward flow and seals when flow reverses. | Best suited for high-pressure systems and horizontal installations. |
| Wafer Check Valves | Compact and lightweight, installed between flanges for space-saving applications. | Commonly used in chemical, water, and HVAC systems. |
All Lianhe non-return valves are available with threaded, flanged, or welded connections to fit various piping configurations.
Our stainless steel check valves combine robust materials with advanced design to ensure long-term reliability. Made from premium stainless steel, they provide excellent corrosion resistance, high-temperature endurance, and extended service life. Each valve complies with ISO, CE, and ECA certifications for consistent quality and safety.
Manufactured to international standards including ISO4144, MSS SP114, and DIN.
Precision-engineered for smooth operation and tight sealing.
Designed for environmental protection and minimal maintenance.
Industrial check valves maintain process integrity and safety by preventing reverse flow that could cause contamination or equipment damage. Lianhe’s stainless steel models are widely used in:
Oil and gas transportation
Chemical and petrochemical processing
Water treatment and environmental systems
Food and beverage production
Construction and HVAC installations
These valves are compatible with stainless steel and carbon steel piping and handle water, steam, gas, and other industrial fluids effectively.
Choosing the right check valve depends on system pressure, temperature, and fluid characteristics. The table below provides general guidance to help you select the most suitable design.
| Factor | Recommendation |
|---|---|
| Pressure Range | Lift check valves for high-pressure systems; swing types for low-pressure flow. |
| Flow Medium | Wafer valves for clean fluids; swing types for viscous or particulate fluids. |
| Connection Type | Threaded for small systems, flanged for industrial pipelines, welded for permanent setups. |
