Feature/Criteria |
Lift check valves |
Swing check valves |
Spring-loaded check valves |
|
Operation |
Disc lifted by fluid flow, closes by gravity or back pressure |
Hinged disc swings open with flow, closes when flow reverses |
Spring mechanism compresses to open, expands to close |
|
Advantages |
Good sealing for high-pressure applications |
Low pressure drop Suitable for fluids with suspended solids |
Fast response to flow changes Can be installed in any orientation |
|
Limitations |
Lift check valve pressure drop is higher due to disc lifting Limited to horizontal installation Sensitive to debris, which can obstruct disc movement |
Generally limited to horizontal installation Slower response, allowing potential backflow before sealing |
Higher cost due to spring mechanism Potential for spring wear in high-cycling applications |
Materials
Valve Body
- Stainless Steel
Stainless steel swing check valves are durable and resistant to corrosion and rust, making them suitable for many applications. However, they may not be cost-effective for systems with low pressures or temperatures.
While generally resistant to corrosion, not all stainless steel grades are suitable for saltwater applications. 316 stainless steel is recommended for such environments due to its enhanced resistance to chloride-induced corrosion.These valves typically operate effectively within a temperature range of -20°C to 200°C (-4°F to 392°F).
- Brass
Brass swing check valves are suitable for high-temperature and high-pressure applications and are more cost-effective than stainless steel valves.
They operate effectively within a temperature range of approximately 0°C to 90°C (32°F to 194°F).
Valve Seat
- NBR
NBR seats are resistant to oil and have high abrasion resistance.
These seals' working temperatures range from -35°C to 120°C (-31°F to 248°F).
- Metal
While offering high-temperature and pressure resistance, metallic seats are more prone to leakage than rubber seats and may need corrosion protection in specific environments.
The exact temperature range depends on the specific metal used.
