Single Plate Check Valve – Frequently Asked Questions
A Single Plate Check Valve, also known as a thin wafer check valve, prevents backflow in pipelines, ensuring unidirectional fluid flow. It is commonly used in water, chemical, and industrial applications where space is limited.
Our Single Plate Check Valves are manufactured from stainless steel, carbon steel, and cast iron, offering durability, corrosion resistance, and long operational life.
The valve allows fluid to flow in one direction while preventing reverse flow. The single plate opens under forward flow pressure and closes automatically when the flow reverses, protecting pumps and pipelines from damage.
Single Plate Check Valves are available in sizes ranging from 2″ to 24″ and pressure ratings including ANSI 150#, 300#, and DIN standards, suitable for various industrial applications.
Yes. We offer OEM customization for body material, plate type, sealing material, and dimensions to meet specific operational requirements.
