FLUOROSEAL RANGE: SPECIAL SERVICE VALVES

Whether you are looking for a valve to suit a specific application, or want to customize a standard FluoroSeal® Plug Valve, you have come to the right place. Our special service valves provide you with both an array of turn-key solutions and the ability to fully match your application needs.

CAGED CONTROL PLUG VALVES

The Caged Control Plug Valve is ideal for abrasive applications with high solids concentrations and is commonly used in both throttlings and on/off applications. Caged valves have been used successfully in many critical applications in the 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.

SPECIAL CLEANING PLUG VALVES

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 unidirectional valve which is indicated on the valve with a flow direction arrow.

FluoroSeal® Sleeved Plug Valves are manufactured in accordance with the recommendations of the Chlorine Institute Pamphlet 6 and provide superior performance on this demanding application. All FluoroSeal® Chlorine Valves are made from thoroughly cleaned and dried components under controlled conditions and this control is maintained throughout parts preparation, assembly, testing and special protective packaging.

DOUBLE BLOCK & BLEED

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.

A 1/2” (12.7 mm) drain connection is standard, but other sizes can also be provided. Specify connection size; length as indicated on the drawing and whether the bleed valve is required.

FIRE SAFE SLEEVED PLUG VALVES

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.
