Plug Valves




FluoroSeal® Lined Plug Valves

Available configurations:

  • 2 Way:
  • Class 150 lbs Flanged, 1/2" to 14" (PN16, DN25 to DN150)

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
  • avity-free both in open and closed position which avoids particle accumulation and it is 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 and additional sealing levels (achieved by a delta ring and PTFE diaphragm) which provides tight shutoff and compression seal (upstream and downstream)

State-of-the-art EZ-SEAL® adjustment mechanism, available on sizes 1/2” to 6”.

Severe Service (FE)

Special Service

  • Caged Control
  • Special Cleaning
  • Double Block & Bleed
  • Fire Seal
  • HF Alkylation



FluoroSeal® Inc. has developed the Severe Service (FE) Sleeved Plug Valve for tight emission control in more demanding applications. This valve is intended for applications in processes involving thermal cycling or a high number of mechanical operations. This compact but robust package is based on the standard FluoroSeal® Sleeved Plug Valve design combined with other proven seal technologies.

Extensive field experience has demonstrated this valves' ability to perform in a variety of severe applications. FluoroSeal® Severe Service (FE) Valves have one of the best fugitive emissions test results on the market, as demonstrated by independent lab testing. Please ask your local Representative for a full fugitive emission test report.




The Caged Control Valve is ideal for abrasive applications with high solids concentrations and is commonly used in both throttling and on/off applications: Mining, Pulp & Paper, and Chemical Processing industries. 

The design of the Caged Control Valve provides maximum protection to the polymer sealing surfaces in the plug valves. The key to the caged design is that the PTFE sleeve in the valve is never directly exposed to the process flow. This allows the sleeve to maintain its sealing integrity in abrasive applications.


FluoroSeal® Special Cleaning Plug Valves can be prepared for a variety of demanding service applications, such as hydrogen, isocyanate, oxygen, phosgene and chlorine.

In the case of chlorine, FluoroSeal® Chlorine Service Valves are provided with a vented plug to relieve pressure to the upstream side. This modification results in a uni-directional valve which is indicated on the valve whith a flow direction arrow.


Because of the double port seals in both directions and the sealed isolation of the chamber below the plug and the areas around the plug, 90° to the port openings, a drainage connection into the plug cavity may be drilled and tapped through the body from the bottom.

Drain connection 1/2” is standard, but sizes 3/4” and 1” can also be provided. Block valve sizes 2" through 24”.


FluoroSeal® Sleeved Plug Valves with the Fire Safe top seal have been tested and certified by an independent laboratory to the requirements of API 607, Fifth Edition (ISO 10497-5) for external leakage.

FluoroSeal® Fire Safe Valves also utilize a vented plug designed to relieve pressure buildup resulting from expansion of the service media within the plug, due to elevated temperatures caused by fire. The pressure is relieved to the upstream side, providing a preferred flow direction indicated by an arrow on the valve cover. 


FluoroSeal® HF Alkylation Valves are designed and manufactured in strict compliance with the requirements of the HF Alkylation’s Process Licensor specifications. Due to the severity of the process, all testing procedures are strictly adhered to per Licensor’s requirements

FluoroSeal® Inc.’s commitment to high quality requires each valve body to be subjected to a hydrostatic shell test at 1.5 times the ANSI rating at 100°F (38°C), as defined in ASME B16.34 (DIN EN 12266-1). In addition, every valve body casting is tested with helium gas at 450 psig for 100% assurance of nothrough-wall leakage. We also conduct a full X-Ray test on the bodies to ensure that they meet FluoroSeal® Inc.’s casting requirements per ASTM E446 (DIN EN 444 and DIN EN 462).
