What is a slab gate valve?

The slab gate valve is a sliding valve whose closing parts are parallel gates. The closing part can be a single ram or a double ram with a stretching mechanism in between. The pressing force of the gate to the valve seat is controlled by the medium pressure acting on the floating gate or the floating valve seat. If it is a flat gate valve with double gates, the expansion mechanism between the two gates can supplement this pressing force.
Slab gate valves can be divided into manual slab gate valves, pneumatic slab gate valves and electric slab gate valves according to the driving mode. According to the purpose and use occasion, it can be divided into flat gate valve with diversion hole, flat gate valve without diversion hole, oil field flat gate valve, pipeline flat gate valve and gas flat gate valve, etc.
