Nitrilc Butadiene Rubber. Trade name: Buna-N. A moderate-service synthetic rubber (polymer) typically used as a seat or o-ring seal in valves because of its abrasion resistance, resistance to degradat [..]

Aluminum Bronze. An alloy containing aluminum and bronze, used in the manufacture of butterfly valve discs. The combination of the two alloys offers moderate corrosion resistance, less weight on the v [..]

Acrylonitrile Butadiene-Styrene. A thermoplastic resin offering excellent corrosion resistance, tensile strength and a temperature rating matching CPVC (180 degrees Fahrenheit). ABS is used to manufac [..]

Brass. An alloy containing a lesser amount of the element, copper as compared to Bronze. As a forging, brass is used to make valve bodies. Other variants of manufacture, including casting, allow broad [..]

Bronze. An alloy containing the element copper. Chiefly used to make valve bodies, it is typically cast into shape. Bronze has moderate corrosion resistance, and excellent high-temperature resistance.

Cast Iron. Describes the material type of certain valve components. Cast iron is comprised of the base element iron, and is mixed with other base elements, which results in the alloy, cast iron. Also [..]

Close. Describes pipe nipple length. A nipple with no space between the pipe threads. Installations using a close nipple bring the two valves or fittings “close” to one another for space-saving reason [..]

Chrome-Plated. Describes the electrostatic or dipped process of applying a chrome finish onto a valve or fitting for purpose of improving appearance or durability. There are two types of final chrome- [..]

Chlorinated Polyvinylchloride. A thermoplastic resin offering excellent corrosion resistance, tensile strength and superior temperature resistance compared to PVC. Like PVC, CPVC is also used to manuf [..]

Carbon Steel. Describes an alloy type typically used in the construction of valve bodies because of its exceptional strength properties. Can be cast or forged.
