Product Introduction
Wafer check valve is a type of check valve with a very short structural length that is connected by being clamped between a pair of pipeline flanges. It relies on the flow force of the medium itself to automatically open and close. When the medium flows downstream, the valve disc opens, and when it flows upstream, the valve disc quickly closes to prevent the medium from flowing back. Its core features are small size, light weight, and compact installation space, making it an ideal choice for environments with limited installation space. TISCO's products comply with standards such as API 594 and API 6D, ensuring reliable operation in petroleum, chemical, power, water supply and other systems.

Features
Adopting a clamp type connection, the structural length is much shorter than that of a flange connected check valve, greatly saving installation space and weight. The valve disc structure has various forms such as rotary opening, butterfly (double disc clamping), and lifting, with rapid opening and closing and minimal water hammer effect. The low flow resistance coefficient has little impact on the pressure drop of the pipeline system. Widely used in compact space applications such as pump outlets and compressor outlets that require prevention of medium backflow.
