Dual Plate Check Valve – Expanded View

1. Body – Made from A216 WCC, the valve body ensures durability and strength, providing resistance to high pressure and harsh conditions.
2. Bonnet – Constructed with A105, the bonnet enhances the structural integrity of the valve, ensuring long-lasting performance.
3. Seat – The seat is manufactured from 410 + HF, offering superior resistance to wear and corrosion, which is essential for long-term use in challenging environments.
4. Arm – Crafted from A216 WCC, the arm supports the internal mechanism, ensuring smooth operation during flow control.
5. Disc – The disc is made from A216 WCC + 316. This combination provides excellent corrosion resistance and strength, ensuring that the valve remains functional even under extreme conditions.
6. Shaft – The shaft, made from 316 SS (stainless steel), ensures high tensile strength and excellent resistance to corrosive elements.
7. End Cap – Constructed from A105, the end cap helps maintain the overall structure of the valve, keeping it secure and leak-proof.
8. Bearing – Made from Nitronic 60, the bearing offers excellent wear resistance and galling prevention, contributing to the valve’s overall durability.
9. End Bearing – Similar to the bearing, the end bearing also uses Nitronic 60, enhancing the valve’s longevity and operational reliability.

Dual Plate Design for Enhanced Performance

The dual plate design of the wafer check valve ensures that it opens and closes swiftly with the flow, preventing water hammer and reducing pressure loss. This makes it an ideal solution for applications where energy efficiency and flow control are critical. The dual plates also allow for a more compact and lightweight construction, making the installation process easier and reducing the overall footprint of the system.
