CHECK VALVE
SWING CHECK VALVE
The Swing Check Valve is engineered to prevent reverse flow in pipelines, ensuring the safety and efficiency of fluid handling systems. Its swinging disc mechanism opens with forward flow and closes automatically when the flow stops or reverses, protecting pumps, compressors, and other equipment from damage.
Highlights:
- Reliable backflow prevention: Ensures fluid only moves in the intended direction.
- Low maintenance design: Minimal moving parts for long service life.
- Versatile materials: Cast iron, carbon steel, stainless steel, and alloy options.
- Flexible installation: Suitable for horizontal or vertical pipeline configurations.
- Industry standards: Manufactured according to API 6D, ANSI, and ISO requirements.
Common Applications:
Widely used in oil & gas pipelines, chemical plants, water treatment systems, and industrial process lines where safeguarding against backflow is critical.
WAFER CHECK VALVE
The Wafer Check Valve is a compact and reliable solution for backflow prevention in oil, gas, and petrochemical pipelines. Its wafer-style design allows it to be installed between flanges, saving space and reducing weight while maintaining high-performance flow control. The valve’s disc swings or tilts to allow forward flow and closes instantly to prevent reverse flow, protecting pumps, compressors, and critical pipeline infrastructure.
Key Features for Petroleum Applications:
- Compact, space-saving design: Fits easily between standard pipeline flanges.
- Rapid response: Disc closes quickly to prevent backflow and water hammer in high-pressure systems.
- Durable materials: Available in carbon steel, stainless steel, and alloy materials suitable for oil, gas, and petrochemical fluids.
- High-pressure and high-temperature rating: Engineered to withstand demanding petroleum environments.
- Low maintenance: Minimal moving parts for long-term reliability.
- Industry standards: Compliant with API 594, ANSI, and ISO, ensuring safe operation in critical systems.
Applications in Petroleum & Petrochemical Industry:
- Oil and gas transport pipelines
- Refineries and processing plants
- Petrochemical and chemical plants
- Offshore platforms and onshore pumping stations
- Any high-pressure, high-flow pipeline requiring reliable backflow prevention
