Wafer Type Check Valves
The Wafer Type Check Valve (PN16) is a compact and lightweight valve designed to prevent backflow in various piping systems, ensuring efficient flow control and protecting equipment from potential damage caused by reverse flow. This valve operates automatically, with a spring-loaded disc that opens when fluid flows in the desired direction and closes to block reverse flow.

With a pressure rating of PN16, it is ideal for medium-pressure applications across industries such as water treatment, HVAC, oil & gas, and chemical processing. Its wafer-style design allows for easy installation between two flanges, making it a space-saving solution suitable for tight piping configurations.
- Valve Size: Typically available from 2" to 24" (DN 50 to DN 600).
- Pressure Rating: PN16 (16 bar / 230 psi).
- End Connections: Wafer-type design fits between two flanges, compatible with flanges as per EN 1092-1 or ASME standards.
- Body Material:
- Carbon Steel (EN 10213-2/ASTM A216 WCB)
- Stainless Steel (EN 1.4408/ASTM A351 CF8M)
- Ductile Iron (EN-GJS-400-15)
- Disc Material: Stainless steel or alloy steel for durability and corrosion resistance.
- Sealing: Soft-seated (EPDM, NBR, PTFE) or metal-to-metal options depending on the application and media handled.
- Design Standards: API 594, EN 12334, ensuring performance and reliability in line with industry standards.
- Compact Wafer Design: The slim, wafer-style body is designed to fit between flanges, minimizing space requirements and allowing for easy installation in compact systems.
- PN16 Pressure Rating: Rated to handle pressures up to 16 bar (230 psi), making it suitable for medium-pressure applications.
- Backflow Prevention: The spring-assisted disc ensures fast closure to prevent reverse flow, protecting critical components such as pumps and compressors.
- Low Pressure Drop: The streamlined internal design ensures minimal flow resistance, promoting efficient operation with low energy consumption.
- Corrosion Resistance: Available in various materials, including stainless steel, carbon steel, and ductile iron, to ensure resistance to corrosion and compatibility with different media.
- Maintenance-Free: The simple, robust construction and self-actuating design minimize the need for regular maintenance, reducing operational costs over time.
- Dual Plate Disc: The dual-disc design enhances performance by providing fast, responsive closing action, reducing water hammer effect.
Testing & Certification:
- Hydrostatic and pneumatic testing in accordance with EN 12266-1.
- ISO 9001 certified manufacturing process.
