The Tilting Disc Check Valve features a pivot point at the center of its disc, addressing the limitations of traditional swing check valves. Unlike swing check valves, which require higher fluid velocities to remain open, the tilting disc check valve can stay fully open and stable at lower flow rates. This results in a lower cracking pressure and reduced pressure drop under low-flow conditions, making it more efficient in such environments. However, at higher flow rates, the tilting disc check valve experiences a higher pressure drop compared to the swing type. This valve is ideal for applications where low pressure drop at low flow rates is critical.

Product Features

» Impact-free Operation: When closed, the valve contacts the sealing surface slowly, ensuring no impact and minimizing noise.
» Excellent Sealing Performance: Equipped with micro-elastic metal seats for reliable sealing.
» Butterfly Disc Design: Allows for quick opening and closing, contributing to a long service life.
» Streamlined Fluid Passage: The tilting disc structure creates a smooth flow path, reducing flow resistance and improving energy efficiency.
