Specs of Sleeve Plug Valve

Valve Body Material

Sleeve Plug Valve is made from high-quality stainless steel, providing excellent durability and resistance to corrosion. You guessed it! This material choice makes the valve suitable for harsh environments and various industrial applications.

Pressure Rating

Sleeve Plug Valve is designed to operate under high-pressure conditions, with a maximum pressure rating of up to 40 bar (580 psi). This high pressure tolerance provides reliable performance in demanding applications. The valve’s robust construction and design offer consistent operation even in extreme conditions.

Actuation Options

NTVAL offers various actuation options for the Sleeve Plug Valve, including manual, pneumatic, and electric actuators. These options provide flexibility in operation and control, allowing integration with different automation systems. The actuators are designed for easy installation and maintenance, ensuring smooth and efficient valve operation.

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

Easy Operation and Maintenance

The low torque operation makes the Sleeve Plug Valve easy to handle, reducing operator fatigue and the need for extensive training. But wait, there's more, this feature also simplifies maintenance, as less force is required to operate the valve, reducing the likelihood of damage during use.

Enhanced Safety During Maintenance

The double block and bleed capability allows for safe maintenance procedures. By isolating sections of the pipeline, it eliminates the risk of exposure to pressurized fluids. This feature is crucial for maintaining safety standards and protecting workers during system checks and repairs.

Increased Safety in Hazardous Environments

The anti-static device reduces the risk of ignition in flammable environments, enhancing overall safety. This feature is vital for industries dealing with explosive materials, as it minimizes the potential for dangerous incidents caused by static discharge.

Applications of Sleeve Plug Valve

Mining and Metallurgy

In the mining and metallurgy industries, the Sleeve Plug Valve is used to control the flow of slurry, water, and other fluids. Its construction allows it to withstand abrasive materials and harsh conditions. The bottom line is that it’s a valuable component in ore processing and metal extraction operations.

Oil and Gas Industry

NTVAL’s Sleeve Plug Valve is widely used in the oil and gas industry for controlling the flow of crude oil and natural gas. Its ability to handle high pressures and temperatures makes it ideal for upstream, midstream, and downstream applications. The valve’s durability and reliable performance are crucial for operations in this demanding sector.

Water Treatment Facilities

Water treatment facilities utilize the Sleeve Plug Valve to control water flow and pressure throughout their systems. The valve’s full-bore design ensures efficient fluid transfer, reducing energy consumption. For example, in a municipal water treatment plant, the Sleeve Plug Valve can help manage the flow of treated water into distribution pipelines, maintaining consistent supply and pressure.

Chemical Processing

In chemical processing plants, Sleeve Plug Valves play an essential role in managing the flow of corrosive chemicals and aggressive fluids. Their design resists chemical wear and minimizes leakage, making them suitable for handling hazardous materials. These valves contribute to maintaining safe and efficient processing, even in applications where chemicals are highly reactive or abrasive.

4 Considerations When Buying Sleeve Plug Valve

01

Compatibility with Existing Systems

Check the compatibility of the Sleeve Plug Valve with your existing systems. The valve should have compatible connection types, such as flanged or threaded ends. For optimal integration, NTVAL recommends choosing valves with standard flange sizes like ANSI 150, 300, or 600.

02

Flow Direction

Check if the Sleeve Plug Valve supports bi-directional flow. Valves that allow flow in both directions offer greater flexibility and can simplify system design. Look for this feature to enhance operational efficiency.

03

Operating Torque Less Than 50 Nm

Consider the operating torque of the Sleeve Plug Valve. Low torque operation reduces the energy required to open and close the valve. A valve with an operating torque of less than 50 Nm (newton meters) is generally easier to operate and integrate into automated systems.

04

10-30 kg Weight

Evaluate the weight of the Sleeve Plug Valve, especially if installation will be in a challenging location. Lighter valves within the 10-30 kg range are easier to handle and install, making the process more efficient. Selecting a valve that balances weight with durability can simplify installation and maintenance in demanding environments.
