Introduction to Check Valve

A check valve is an automatic pipeline valve designed to allow fluid, gas, or steam to flow in only one direction, preventing backflow. It protects equipment, stabilizes system pressure, prevents contamination, and improves process safety. Available in axial flow, dual plate, lift, swing, and tilting disc designs, check valves are widely used in water treatment, petrochemical, energy, machinery, and civil pipeline systems. When backflow prevention matters, trust NIPO's precision-engineered check valves to protect your equipment and maintain process integrity.

Why Choose NIPO Check Valves

Protect your pipeline system from backflow and water hammer—choose a high-performance swing check valve engineered for safety, stability, and long-term reliability.

Adjustable Closing Control for Water Hammer Protection

Adjustable Closing Control for Water Hammer Protection

This swing check valve is designed with an external adjustable counterweight, allowing precise control of the disc closing speed and final seating force. By enabling staged slow closing or quick closing modes, the check valve effectively suppresses water hammer and absorbs pipeline impact energy. This helps protect pumps, pipelines, and fittings from pressure surges, extending system service life in water treatment, power, and industrial pipeline systems.

Reliable Sealing Performance in Complex Working Conditions

The counterweight-assisted swing check valve provides stable closing force independent of medium backflow, ensuring tight sealing even under low pressure, vertical installation, or fluctuating flow conditions. Its robust design performs reliably with viscous or particle-containing media such as sewage, slurry, and industrial fluids, reducing leakage, disc flutter, and wear while enhancing overall backflow prevention and system safety.

FAQs about Check Valve

Q: How do I select the right check valve type for my application?
A: Consider flow direction, installation orientation, pressure drop requirements, and media characteristics. Our engineers can provide selection assistance.
Q: What causes check valve failure and how can I prevent it?
A: Common causes include water hammer, improper installation, and debris accumulation. Proper sizing, orientation, and regular maintenance prevent most issues.
Q: Can check valves be installed in vertical pipelines?
A: Lift check valves work in vertical upward flow, while swing check valves require horizontal installation. Dual-disc valves work in any orientation.
Q: What's the difference between metal and resilient seating?
A: Metal seats offer higher temperature/pressure capability, while resilient seats provide tighter shut-off for low-pressure applications.
Q: Do you provide actuated check valves?
A: Yes, we offer pneumatic and electric actuators for applications requiring positive opening/closing control.
