Gate valves
The GMI gate valve has a disc which moves linearly, perpendicular to the direction of flow at the valve seats. It can have angled seats (single-wedge disc, flexible-wedge disc) or parallel seats (free expansion, self-tightening, slice gate valve, gate valve with seat ring). External sealing is obtained using a stuffing box or, less commonly, a bellows. The gate valve acts as a shut-off device for a fluid, whether gas or liquid.
