Wafer Swing Check Valve Supplier – Price, Design & Industrial Dealers India
Wafer swing check valves are essential components in fluid handling systems, designed to prevent backflow and ensure unidirectional flow. Their slim wafer-style body makes them ideal for compact installations between flanges. Widely used in water, HVAC, fire fighting, and process systems, these valves are available in cast iron, stainless steel, and ductile iron variants.
What is a Wafer Swing Check Valve?
A wafer swing check valve consists of a disc that swings on a hinge or trunnion, allowing fluid flow in one direction and automatically closing to prevent backflow when flow reverses. Unlike conventional check valves, the wafer design offers space-saving and lightweight construction.
Key Features
- Compact wafer body fits between flanges (PN10/PN16)
- Single disc with swing action for low pressure drop
- Low-maintenance and corrosion resistant materials
- Horizontal or vertical flow installation (check manufacturer)
- Available with soft or metal seat
Types of Wafer Swing Check Valves
- Cast Iron (CI) Body: Economical for water and non-corrosive applications
- Stainless Steel 304/316: For corrosive and hygienic applications
- Ductile Iron (DI): Higher strength, ideal for buried or high-pressure pipelines
- Rubber Lined / Nitrile Seat: Quiet operation and leak-tight sealing
Applications
| Industry | Application |
|---|---|
| Water Treatment | Prevents pump backflow, protects pipelines |
| Fire Protection | Used after fire pumps to prevent reverse flow |
| HVAC Systems | Maintains flow direction in chilled/hot water systems |
| Chemical Industry | Stainless steel variants for process lines |
| Irrigation | Non-return functionality in open/closed channel systems |

FAQs – Wafer Swing Check Valves
Q1. What is the use of a wafer swing check valve?
It prevents fluid from flowing backward and protects pumps and piping systems from pressure reversal.
Q2. Can it be installed vertically?
Yes, but ensure the flow direction is upward and manufacturer guidelines allow it.
Q3. What is the pressure rating of these valves?
Commonly PN10 or PN16; custom designs available in higher ratings.
Q4. Are stainless steel swing check valves suitable for seawater?
Yes, especially if made from SS 316 or duplex grades with PTFE seats.
Q5. How do I know the valve is closing properly?
Hydrostatic testing and backflow simulation ensure reliable closing. Ask for test reports.
