UAE Valve is the leading Non Rising Stem Gate Valve Supplier in Dubai. A non rising gate stem in a gate valve means the stem will turn to open and close the gate, but the stem does not move up or down as it turns & the stem remains stationary while the valve’s internal mechanism moves. the design allows the stem of the gate valve to be fully open when the handle is rotated to the left and fully closed when the handle
Design:
1.Body: The body connects to the piping at both ends and can be made from materials such as cast iron, carbon steel, stainless steel.
2.Bonnet: The bonnet encases the valve stem and provides a seal. the stem and the gate, maintaining pressure containment and preventing fluid leaks
3. Gate: The gate is a solid disk inside the valve body. It is raised or lowered to open or close the valve. In non-rising stem gate valves, the gate remains fixed onto the stem while the stem itself does not move up or down
Function:
A non-rising stem gate valve functions by using a threaded stem that remains stationary while the gate moves up and down to open or close the flow. The stem is threaded on the inside and connects directly to the gate, which moves along the stem’s threads when the handwheel is rotated.
Advantages:
•Space Efficiency: The non-rising stem design is ideal for installations where vertical space is limited as the stem does not extend upward when the valve is operated.
•Maintenance: The valve’s compact design can be more aesthetically pleasing and easier to maintain in confined spaces.
•Durability: Often constructed to handle high-pressure and high-temperature applications, making them durable for demanding environments.
•Sealing Capability: Provides a reliable seal to prevent leakage, especially useful in critical isolation application
