main types of slide gate valves

2012-06-08

Since the gate inside an industrial Gate Valve takes a linear path through the center of the valve it can cut through thick fluids. This makes industrial gate valves ideal for situations that involve slurry or viscous fluids, like oils or grease.

Here are the main types of slide Gate Valves:

1. In a parallel gate valve, a flat disk divides two parallel seats to achieve shut-off.

2. In a double-parallel gate, two disks with an inclined plane lower between two parallel seats. Once the disks are fully down, the inclined plane presses the disks against the seats.

3. The two seats of a wedged-shape gate valve are inclined and the disc is somewhat mismatched to achieve higher sealing pressure.
