Nil-Cor® Fiber-Composite Ball Valves, Flanged Ball Valves, Vinyl Ester Resin, Graphite Fiber, Sizes 1‚ (300 Series)
Nil-Cor® Fiber-Composite Vinyl Ester Resin, Graphite Fiber (300 Series) Flanged Ball Valve features a one-piece body, eliminating the leak path inherent in a body joint. It is used for corrosive chemical service used in construction of pressurized piping systems, and piping systems requiring electrically conductive valve bodies.
Product Features & Benefits
- ONE-PIECE BODY: The one-piece compression molded, graphite fiber and vinyl ester thermoset resin body eliminates the leak path inherent in a body joint.
- STRONG, DURABLE AND LIGHT WEIGHT: Excellent alternative to high alloy valves. Nil-Cor ball valves are 50% - 80% lower cost and 1/3 the weight. Saves money on piping supports and makes Nil-Cor ball valves ideal for use on plastic and FRP flanged piping systems.
- HIGH STRENGTH AND CHEMICAL INERTNESS: Graphite Fibers provide high strength and chemical inertness, conductivity and surface lubricity to valve moving parts.
- BROAD CHEMICAL RESISTANCE RANGE: The vinyl ester resin, graphite fiber composite valve offers the same chemical resistance properties as the 310 series (vinyl ester resin/glass fiber) but at higher temperatures. The Vinyl Ester/Graphite Fiber 300 series resists certain chemicals that might attach glass fibers.
- CORROSION RESISTANT, SAFE AND RELIABLE: All Nil-Cor ball valves feature lightweight, corrosion resistant bodies, no wetted metallic components and a lock-out as standard equipment.
- UNIQUE COLOR CODING: All valves have unique color coding for easy field identification.
