FluoroSeal® Lined Plug Valves use high precision investment casting method for all major pressure holding components. The standard base model offers:
Carbon Steel body, plug and cover (ASTM A216 Gr. WCB).
Low porosity PFA (Perfluoroalkoxy) as standard liner
All cast parts have an acrylic based coating prior to lining for added protection from corrosion attack due to permeation
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 feature 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
* Patent pending
