The Sant Dual Plate Wafer Check Valve is a high-performance, non-return valve engineered to prevent reverse flow in piping systems. Designed with two spring-loaded plates (discs), it ensures quick closing and minimizes pressure drop, making it highly efficient in fluid handling applications. Its compact wafer-style body allows easy installation between flanges, saving space and reducing overall system weight.
Constructed with durability in mind, the valve is available in a variety of materials, including Cast Iron, Carbon Steel, and Stainless Steel, with disc and spring options to match different media and temperature requirements. The valve also features soft or metal seating options, providing leak-tight sealing for a wide range of applications.
The dual-plate design reduces the risk of water hammer and supports non-slam operation, even in systems with high flow velocity. The Sant Dual Plate Wafer Check Valve is suitable for both horizontal and vertical installations, offering operational flexibility in compact or complex piping layouts.
Common applications include water supply systems, HVAC, fire protection, oil and gas pipelines, and industrial processing plants. The valve complies with international standards such as API 594 for design and API 598 for testing, ensuring reliable performance and long service life.
Its low maintenance requirement, lightweight design, and corrosion-resistant construction make it a cost-effective and dependable solution for preventing backflow. Whether for fresh water, seawater, air, steam, or chemicals, Sant’s check valve offers dependable protection and efficient flow control.
