Viti Industry provides you with an easy-to-understand introduction to the structural principles of five commonly used valves

Wedge gate valves of Viti Industry

Gate valve: A gate valve moves the gate plate perpendicularly along the centerline of the valve seat, causing the sealing surface of the gate plate to adhere to the valve seat. It relies on top wedges, springs or wedge-shaped structures to enhance sealing and block the flow of the medium. ‌

Viti Industry's anti-erosion high-pressure stop valve

Stop valve: The valve disc moves vertically along the center of the valve seat. The valve stem thread applies pressure to make the sealing surface closely adhere, thus cutting off the flow of the medium. ‌

The lift check valve of Viti Industry

    Check valve (one-way valve) : It automatically opens and closes based on changes in fluid pressure to prevent reverse flow of the medium. It mainly relies on fluid power to drive the closing part to swing or move. ‌

Wear-resistant ball valves from Viti Industry

Ball valve: The valve disc is a through-hole ball that rotates around the center of the valve body to adjust the position of the through hole, controlling the flow or cut-off of the medium. ‌

High-performance butterfly valves from Viti Industry

    Butterfly valve: The disc-shaped valve disc rotates around the inner axis of the valve seat to achieve opening and closing. The flow rate is regulated by changing the relative position of the disc and the valve seat.
