Tilting Disc Check Valve Overview
Características de design
A tilting disc check valve has a disc on a pivot. The disc tilts open when fluid moves forward. It closes fast if the flow goes backward. This design helps liquids and gases move easily. It lowers pressure loss and stops backflow. The STV 150LB tilting disc check valve is strong. Its CF8M stainless steel body fights rust well. The valve is 24 inches wide and has a wafer-type shape. It fits big pipes and small spaces. It works well with pressure up to 150lb. It can handle temperatures from -29°C to 300°C. STV Valve Technology Group Co., Ltd makes this valve. The valve meets ASME B16.34 and API594 rules. This means it is high quality and works the same every time. The company gives wafer and wafer lug ends. This makes it easy to install.
STV Valve Technology Group Co., Ltd is known for making 150LB tilting disc check valves. They also make CF8M tilting disc check valves, 24 inch tilting disc check valves, and wafer tilting disc check valves. Their products are good quality and not too expensive. Many people trust them for big projects.
Typical Uses
Engineers use the tilting disc check valve in many jobs. It lets fluid go one way and stops it from going back. This valve works with water, oil, natural gas, and some harsh fluids. It reacts fast and does not waste much pressure. This makes it good for tough systems.
| Application Area | Descrição |
|---|---|
| Water Treatment Facilities | Used for low-pressure loss and quick response to backflow. |
| Oil and Gas Pipelines | Essential for preventing backflow in high-pressure systems. |
| Petrochemical Industries | Helps maintain one-way flow and system integrity. |
| Power Plants | Critical for boiler feedwater systems to prevent backflow. |
- People put these valves in places like:
- Pump outlets
- Piping systems
- Boiler feedwater systems
The tilting disc check valve helps keep these places safe and working well. That is why many factories use it.
Check Valve Types
Knowing about the main check valve types helps engineers pick the right one. Each type stops backflow in its own way. Here are three common types used in factories.
Swing
A swing check valve has a disc on a hinge. When fluid moves forward, the disc swings open. If the flow goes backward, the disc swings shut. This valve can slam hard when closing. It can cause more pressure loss and needs more fixing. Swing check valves work best in pipes that go sideways and have steady flow.
- The disc hangs on a hinge.
- The valve shuts if flow goes backward.
- Closing can make a loud slam.
Note: Swing check valves are easy to use and common, but they might not work well if flow changes quickly.
Lift
A lift check valve has a disc that moves up and down. When fluid pushes up, the disc lifts and lets flow through. If pressure drops or goes backward, the disc falls down and closes. This valve seals tight and is good for high pressure. Lift check valves are often used in up-and-down pipes where space is small.
- The disc moves straight up to open.
- Gravity or backward flow shuts the valve.
- Good for high pressure and clean fluids.
Dual-Plate
A dual-plate check valve has two plates with springs. The plates turn on a hinge in the middle. When fluid moves forward, the plates swing open. If flow slows or goes backward, the springs help close the plates fast. This valve does not slam much and loses less pressure. It is small and light, so it fits in tight spots and big pipes.
- Two plates turn on a middle hinge.
- Springs help close the plates fast.
- Less slamming and pressure loss than swing check valves.
Engineers like dual-plate check valves because they are small and work well in tough places.
Each check valve type has its own good points for different jobs. Picking the right valve helps systems work well and last longer.
Performance Comparison
Flow and Pressure Drop
Flow efficiency and pressure drop matter when picking a check valve. The tilting disc check valve from STV Valve Technology Group Co., Ltd has a special disc shape. This shape lets fluid move easily through the valve. The disc tilts open with the flow and shuts fast if the flow goes backward. This helps lower turbulence and keeps the pressure drop at a medium level.
The table below shows how each check valve type handles pressure drop:
| Tipo de válvula | Pressure Drop Comparison |
|---|---|
| Válvula de retenção de disco inclinável | Medium pressure drop, less than lift check valves but a bit more than swing check valves. |
| Válvula de inspeção | Lower pressure drop because the flow path is smooth. |
| Lift Check Valve | Higher pressure drop than swing and tilting disc check valves. |
Swing check valves have less pressure drop since their disc swings away, making a clear path for fluid. Lift check valves have more pressure drop because the disc moves up and down, which can slow things down. The tilting disc check valve is in the middle. It lets fluid move better than lift check valves and is almost as good as swing check valves. This makes it a good pick for systems that need good flow and to stop backflow.
Sealing and Reliability
Sealing and reliability are very important for check valves. The tilting disc check valve from STV uses a pre-loaded gasket and the pressure from the fluid to make a tight seal. This design helps stop leaks and keeps the system safe. The valve closes fast if the flow goes backward, which stops backflow and water hammer.
STV makes its tilting disc check valve to meet ASME B16.34 and API594 rules. These rules make sure the valve works well when pressure or temperature changes. The strong build lets the valve work in tough places, like where it is hot or the fluid can cause rust.
Other check valves also seal well, but the tilting disc check valve is special because it closes fast and shuts off well. Swing check valves might close slower, so some backflow can happen. Lift check valves seal tight but may not close as fast if the flow changes. Dual-plate check valves use springs to help close quickly, but how well they seal depends on the springs and how the plates line up.
Maintenance and Durability
Maintenance and durability are important for how long a check valve lasts. The tilting disc check valve from STV has a simple design with fewer moving parts. This means less wear and easier maintenance. The CF8M stainless steel body does not rust easily, so the valve lasts longer even in hard jobs.
STV checks every valve using API598 rules. This makes sure each valve is high quality before leaving the factory. The strong build and good materials mean the valve can be used a lot and with tough fluids without breaking.
Swing check valves might need more fixing because the disc can slam shut and wear out. Lift check valves have more moving parts, so they might need more repairs. Dual-plate check valves are small and strong, but their springs might need to be changed after a long time.
Tip: Picking a check valve that is strong and easy to fix can help save time and money over the years.
The tilting disc check valve from STV Valve Technology Group Co., Ltd has a low pressure drop, seals well, and is built strong. These things make it a good and trusted choice for many factory jobs.
