PTFE Sleeved Plug Valve

What Are The Types Of PTFE Sleeved Plug Valve?

Standard PTFE Sleeved Plug Valve:
This is the basic configuration featuring a PTFE sleeve lining the plug to provide a self-lubricating surface.

Full Port PTFE Sleeved Plug Valve:
This design offers a full bore opening for maximized flow capacity, while still utilizing the PTFE sleeve for lubrication-free operation.

Reduced Port PTFE Sleeved Plug Valve:
For applications requiring throttling or flow control, this variant has a reduced port size compared to the full port model.

High-Pressure PTFE Sleeved Plug Valve:
Engineered to withstand higher pressures, this reinforced version of the PTFE sleeved plug valve maintains reliable performance in demanding conditions.

Exotic Material PTFE Sleeved Plug Valve:
To accommodate corrosive or specialized service requirements, Cameron offers PTFE sleeved plug valves constructed with exotic materials like alloy steel, titanium, or Monel.

What Is PTFE Sleeved Plug Valve?

PTFE Sleeved Plug Valves are a specialized type of industrial valve designed to provide reliable flow control with minimal maintenance requirements. The key feature of these valves is the incorporation of a PTFE (Polytetrafluoroethylene) sleeve that lines the internal plug surface. This PTFE sleeve acts as a self-lubricating barrier, eliminating the need for regular lubrication while maintaining the tight sealing capabilities typically associated with non-lubricated plug valves. This unique design combines the advantages of both lubricated and non-lubricated plug valves, making PTFE Sleeved Plug Valves a versatile and cost-effective solution for a wide range of industrial applications, particularly in industries where equipment downtime must be minimized.

How to Select the Right PTFE Sleeved Plug Valve?

Application Requirements: Evaluate the specific operating conditions, such as pressure, temperature, and media compatibility, to ensure the valve is suitable for your process.

Flow Capacity: Determine the required flow rate and choose a valve size that can accommodate your system’s needs, whether a full port or reduced port design.

Materials of Construction: Select the appropriate body and plug materials, including exotic options, based on the corrosiveness or abrasiveness of the media being handled.

Actuation: Decide on the preferred actuation method, such as manual lever, gear operator, or automated actuator, to match your installation and control requirements.

Features of PTFE Sleeved Plug Valve

Self-Lubrication:
The PTFE (Polytetrafluoroethylene) sleeve lining the plug provides a self-lubricating surface, eliminating the need for regular lubrication and reducing maintenance requirements.
