FluoroSeal - Lined Plug Valves

FluoroSeal® Lined Plug Valves feature an unpigmented virgin PFA lining applied by Transfer Molding and locked into castings by machined dovetail-shaped grooves, and cast dovetail-shaped recesses in body castings and cast holes.

• Prevents liner collapse in vacuum conditions
• Prevents blow out in high temperature and pressure combined conditions
• Transfer Molding insures equal distribution and consistency of liner throughout the entire surface of the lined components as per ASTM F1545
• No weak sections in the valve liner
• All liner defects are directly visible

By design, Lined Plug Valves are cavity-free both in open and closed positions.

• No particle accumulation
• Ideal for corrosive slurry applications superior sealing capabilities

The interface between the tapered outer plug and the tapered inner body liner provides a 360° primary sealing area. Additional sealing levels are achieved by a delta ring and PTFE diaphragm, both protected by a metal diaphragm. The metal diaphragm assists in encapsulation, acts as an antistatic device, and is a metal seal to atmosphere, in case of PTFE failure.

• Tight shutoff
• Compression seal (upstream and downstream)
• Bi-directional valve
• Sealed at both plug and stem

FluoroSeal® Lined Plug Valves can be fitted with the state-of-the-art EZ-SEAL® adjustment mechanism, available on sizes 1/2” to 6”.

• Single point frontal adjustment — no special tooling needed
• 360° simultaneous and even compression of top seal and plug
• Plug adjustment is linear, impossible to side load
• Integrated Min/Max gauge offers a visual diagnostic of remaining service life and allows for easy maintenance planning
• EZ-SEAL® design significantly reduces recordable leakage
• EZ-SEAL® Bracket and Lock with multiple ISO mounting capabilities and five locking positions are offered in 304 SS as standard
• ISO mount, explosion proof stem design
