The core feature of the Tilting Disc Check Valve is its tilted disc installation, which allows for rapid response to changes in fluid flow direction, reducing water hammer and improving system safety. This valve is widely used in industries such as water supply and drainage, petrochemicals, power generation, heating, shipping, and sewage treatment, and is suitable for media such as liquids, gases, and steam.
Operating Principle
Forward Flow:
When the medium flows, pressure pushes the tilted disc open, allowing fluid to flow smoothly.
Reverse Flow:
When the medium flows backward, the disc quickly closes under its own weight, spring force, or back pressure, preventing backflow.
Water Hammer Suppression:
The tilted disc design allows for premature closure before the flow rate decreases, reducing water hammer and improving system safety.
Structural Components
- Valve Body:
Made of carbon steel, stainless steel, ductile iron, or alloy steel, suitable for various pressure and temperature environments.
- Tilting Disc:
- This key component is typically made of stainless steel or a wear-resistant alloy, with an optimized tilt angle to improve fluid flow capacity. Support Mechanism:
Provides a tilting, fixed, and rotating pivot point for the disc, reducing wear and extending service life.
- Spring (select models):
Spring-assisted closing, suitable for low-pressure applications, increasing closing speed.
- Sealing System:
Metal seal (high-temperature and high-pressure resistant) or soft seal (suitable for low-pressure, high-sealing requirements).
- Connections:
Flange, wafer, welded, and other connection methods.
Features
- Low-resistance, energy-saving design:
Unimpeded flow path, lower flow resistance than traditional check valves, improving system efficiency.
- Quick closing, reducing water hammer:
The swash plate design enables premature closing, preventing backflow and water hammer.
- Excellent sealing performance:
Precision-machined seat and disc ensure long-term, reliable sealing.
- Horizontal or vertical mounting:
Adaptable to various piping layouts, increasing installation flexibility.
- Corrosion-resistant, adaptable to harsh operating conditions:
Available in stainless steel and corrosion-resistant alloys, suitable for seawater and chemical pipelines.
- Long life, low maintenance:
The bearings and pivot points reduce friction, extending service life and reducing maintenance costs.
