Middleeast Valve is the foremost Double disc gate valve manufacturers in Saudi Arabia. A Double Disc Gate Valve, also known as a double-disk gate valve or parallel disc gate valve, is a type of industrial valve used to control the flow of fluids (liquids or gases) within a pipeline. It belongs to the family of gate valves, which are designed to either completely block the flow or allow unrestricted passage when fully open.
A Double Disc Gate Valve features two parallel, flat discs or gates that are positioned between the valve body and the bonnet. These discs are connected to a spindle or stem that can be rotated to raise or lower the gates. When the gates are fully raised, there is a clear passage for fluid flow; when fully lowered, the gates block the flow.
Here's how a Double Disc Gate Valve typically works:
- Open Position: When the valve is fully open, the gates are raised and aligned with the flow path. This allows fluid to pass through the valve with minimal resistance.
- Closing the Valve: To close the valve, the spindle or stem is rotated, causing the gates to move downward. As the gates descend, they block the flow path, creating a tight seal that prevents fluid from passing through.
- Closed Position: When the valve is fully closed, the gates are tightly pressed against the valve seats, ensuring a secure shut-off and preventing any leakage.
- Opening the Valve: To open the valve again, the spindle is rotated in the opposite direction, lifting the gates away from the valve seats and reestablishing the flow path.
Middleeast Valve is well known Double disc gate valve manufacturers in Saudi Arabia and primary function of a Double Disc Gate Valve is to regulate fluid flow by providing a tight seal when the valve is closed and allowing unobstructed flow when fully open. It is often used in applications where a straight-through flow path is required and where a minimal pressure drop across the valve is desired.
Advantages:
- Mininmal pressure drop
- Quick operation
- Straight through flow
- Bi directional sealing
