Check Valves (Non-Return Valves)
CHECK VALVES (NON-RETURN VALVES)
SWING CHECK VALVE
Swing check valve designed to allow fluid flow in one direction and automatically prevent backflow. Features a hinged disc mechanism that swings open with flow and closes when flow reverses. Ideal for water supply systems, pump lines, and industrial pipelines where backflow protection is critical.
| Size | Material | Pressure Class | End Type | Application |
|---|---|---|---|---|
| 1" - 24" | CI / CS / SS | 150 - 300 | Flanged | Water Systems |
| 2" - 48" | CS / SS | 300 - 600 | Flanged | Industrial Pipelines |
LIFT CHECK VALVE
Lift check valve designed for high-pressure systems where quick closure is required. Uses a vertically lifting disc that ensures tight sealing and prevents reverse flow. Suitable for steam lines, gas systems, and high-pressure industrial applications.
| Size | Material | Pressure Class | Connection | Application |
|---|---|---|---|---|
| 1/2" - 12" | CS / SS | 300 - 900 | Flanged / Threaded | Steam & Gas |
| 2" - 16" | SS | 600 - 1500 | Flanged | High Pressure Lines |
DUAL PLATE CHECK VALVE
Dual plate check valve designed for compact installation and efficient backflow prevention. Features two spring-loaded plates that close quickly, reducing water hammer effect. Ideal for modern industrial systems, HVAC, and high-flow pipelines.
| Size | Material | Pressure Rating | Mounting | Application |
|---|---|---|---|---|
| 2" - 24" | CI / CS / SS | 150 - 300 PSI | Wafer Type | HVAC Systems |
| 4" - 36" | CS / SS | 300 PSI | Between Flanges | Industrial Flow |
BALL CHECK VALVE
Ball check valve uses a spherical ball to control flow and prevent reverse movement. Simple design ensures reliable operation and minimal maintenance. Ideal for wastewater, slurry, and viscous fluid handling applications.
| Size | Material | Pressure Rating | Operation | Application |
|---|---|---|---|---|
| 1" - 12" | CI / MS / SS | 150 PSI | Automatic | Wastewater |
| 2" - 24" | MS / SS | 100 PSI | Gravity Flow | Slurry Systems |
WAFER TYPE CHECK VALVE
Wafer type check valve designed for space-saving installation between flanges. Lightweight and compact, it ensures efficient backflow prevention with minimal pressure loss. Widely used in water treatment, HVAC systems, and industrial pipelines.
| Size | Material | Pressure Class | Mounting | Application |
|---|---|---|---|---|
| 2" - 24" | CI / CS / SS | 150 - 300 | Wafer | Water Treatment |
| 4" - 30" | CS / SS | 300 | Between Flanges | Industrial Systems |
