Product Features
ASTM A105 Forged Steel Construction
The valve body is manufactured from ASTM A105 forged carbon steel, providing superior strength compared to conventional cast steel valves.
مزايا
- High pressure resistance
- Excellent structural integrity
- Improved fatigue strength
- Superior impact resistance
- Long service life
Forged steel construction is widely preferred for Class 1500 pressure applications.
Class 1500 High-Pressure Capability
Designed for severe operating environments, the valve can handle high-pressure services commonly found in:
- Refinery units

How the Valve Works
A check valve operates automatically based on flow direction and pressure differential.
Forward Flow
- Flow enters the valve.
- The dual plates open against spring tension.
- Fluid passes through the valve with minimal restriction.
Reverse Flow
- Flow begins to reverse.
- Springs immediately force the plates closed.
- Backflow is prevented.
- Downstream equipment remains protected.
The rapid-closing mechanism minimizes water hammer and pressure shock.
Why Choose a Wafer Check Valve?
Compared with swing check valves, wafer check valves offer several advantages.
| Feature | صمام فحص الرقاقة | صمام الاختيار البديل |
|---|---|---|
| Weight | Lower | |
| Face-to-Face Dimension | Shorter | |
| Water Hammer Resistance | Better | |
| Installation Space | Smaller | |
| Closing Speed | Faster | |
| Maintenance | Lower |
For high-pressure systems, wafer check valves are often preferred due to their compact and efficient design.
