Generally speaking, these two parts cooperate to control the relative
flow. When the gate valve disc is driven out from the valve seat, the flow
would be allowed to go. And when the valve disc is driven to be contact
tightly with the valve seat, the passing flow would be totally
prevented from going through. In order to meet various specifications,
these two parts are also available to be designed and manufactured in a
wide range of shapes. The most common type is the V-shape.
Besides, body and valve bonnet are also indispensable. Actually, they
are all the outer parts of a gate valve. Generally speaking, the valve
body is used to connect the valve to the required pipelines. And the
valve bonnet is used to contain the valve disc. Such two parts aim to
provide a safe working condition for a gate valve. Both can be made of
metal or plastic.
In words, these components cooperate to lead various gate valves to
benefit all attaching industrial process. They are suitable for any
situation requiring immediate and effective shutoff. The future for the
gate valve continues to be much brighter, I believe.
