Before the resilient seated gate valve was introduced to the market, gate valves with a metal seated wedge were widely used. The conical wedge design and angular sealing devices of a metal seated wedge require a depression in the valve bottom to ensure a tight closure. Herewith, sand and pebbles are embedded in the bore. The pipe system will never be completely free from impurities regardless of h...

A butterfly valve is a shut-off valve with a relatively simple construction. In closed position, the disc blocks the valve bore as in open position, the disc is turned to allow flow. A quarter turn takes the valve from fully open to fully closed position, oppositely, the butterfly valve allows for quick opening and closure. Butterfly valves can be used for a broad range of applications within wate...

Check valves are automatic valves that open with forward flow and close with reverse flow. The pressure of the fluid passing through a system opens the valve, while any reversal of flow will close the valve. Exact operation will vary depending on the type of Check valve mechanism. Most common types of Check valves are swing, lift (piston and ball), butterfly, stop and tilting-disk. Types of Check ...

Ball valves A Ball valve is a quarter-turn rotational motion valve that uses a ball-shaped disk to stop or start flow. If the valve is opened, the ball rotates to a point where the hole through the ball is in line with the valve body inlet and outlet. If the valve is closed, the ball is rotated so that the hole is perpendicular to the flow openings of the valve body and the flow is stopped. Types ...
