Swing Check Valve Manufacturer in USA
SVR Global is a leading swing check valve manufacturer in USA, delivers API, ASME, and ISO-certified valves engineered for long-lasting performance. In industries where backflow prevention is essential, swing check valves remain one of the most reliable solutions. Designed to automatically prevent reverse flow in piping systems, these valves protect pumps, compressors, and pipelines from costly damage.
What is a Swing Check Valve?
A swing check valve is a type of non-return valve that uses a hinged disc to allow forward flow and automatically close if the flow reverses. This prevents backflow, maintaining pipeline integrity without human intervention.
Unlike lift check valves, swing check valves offer low-pressure drop, smooth flow passage, and dependable sealing. This makes them suitable for both horizontal and vertical flow applications.
Advantages of Swing Check Valves
· Automatic Backflow Prevention
· Low Pressure Drop
· Versatile Orientation
· Wide Pressure Range
· Durable Sealing
· Low Maintenance
Parts of Swing Check Valves
- Valve Body – Constructed from carbon steel, stainless steel, ductile iron, or exotic alloys.
- Disc (Flap) – Hinged component that swings open for forward flow and closes to block reverse flow.
- Hinge Arm & Pin – Provide pivoting action for the disc.
- Seat Ring – Ensures leak-tight sealing against backflow.
- Bonnet – Houses the hinge mechanism and allows maintenance access.
Types of Swing Check Valves
- Standard Swing Check Valve – General-purpose valve for water, oil, and gas.
- Dual Plate Swing Check Valve – Compact design with two plates, reducing water hammer.
- Tilting Disc Check Valve – Provides quicker response to reverse flow.
- Silent Swing Check Valve – Designed with spring-assisted closing to reduce noise and water hammer.
- Pressure Seal Swing Check Valve – Suitable for high-pressure and high-temperature service.
Industries Using Swing Check Valves -
- Oil & Gas – Pipeline transmission, refineries, LNG terminals in Texas and Louisiana.
- Power Plants – Steam lines, condensate systems, and cooling water loops.
- Water & Wastewater Treatment – Prevents reverse contamination in pumping systems.
- Petrochemicals – Handles aggressive chemicals and prevents costly downtime.
- Marine & Offshore – Protects ship pipelines and ballast systems from backflow.
- General Manufacturing – Used in HVAC, industrial water supply, and process industries.
