Features of Sleeve Plug Valve
Low Torque Operation
The Sleeve Plug Valve's low torque operation makes it easy to open and close, reducing wear on components and prolonging lifespan. It requires less energy, which is beneficial in automated systems. For example, in a chemical plant with frequent operations, the low torque design minimizes strain on equipment and operators.
Double Block and Bleed Capability
This valve features double block and bleed capability, which allows for isolation of the valve from both upstream and downstream pressure. This is crucial for maintenance and safety, as it allows for the system to be depressurized and checked for leaks without complete system shutdown.
Anti-Static Device
NTVAL's Sleeve Plug Valve is equipped with an anti-static device to prevent the buildup of static electricity. This feature is particularly important in applications involving flammable, explosive, or hazardous materials. It enhances operational safety by reducing the risk of sparks that could ignite volatile substances.
Benefits of Sleeve Plug Valve
