Bronze Marine Gate valves Stainless Steel/Copper Electric/Hydraulic/Hand Gate Valve in Ship/Vessel/Boat
The Marine Gate valves is carefully polishing and testing before leaving factory to ensure the performance.
Copper&Bronze/Stainless Steel/Steel material has longer service life for your pipes&vessel.
The opening and closing components of a marine gate valve are the gate,
and the direction of movement of the gate is perpendicular to the direction of the fluid.
The gate valve can only be fully opening and closing, but cannot be adjusting or throttling
The gate has two sealing surfaces,
and the two sealing surfaces of the most commonly using mode gate valve are wedge-shaped.
The wedge angle varies with the valve parameters, usually 50, and is 252 when the medium temperature is not high.
The gate of a wedge-shaped gate valve can be making into a whole, called a rigid gate;
It can also be making into a gate that can produce slight deformation to improve its processability and compensate for the deviation in the sealing surface angle during the processing.
This type of gate is calling an elastic gate.
When the gate valve is closed, the sealing surface can only be sealing with medium pressure,
that is, the sealing surface of the gate valve is pressding against the valve seat on the other side by medium pressure to ensure the sealing of the sealing surface,
which is self sealing. Most gate valves are forcing to seal, which means that when the valve is closing
external force is using to force the gate valve against the valve seat to ensure the sealing of the sealing surface.
