Diaphragm valves, flanged ends, (FKM) fluoroelastomer diaphragm, sizing: 1/2-inch. Schedule 80 pipes are thicker, heavier developed to handle even more PSI than Schedule 40. In the United States, Schedule describes the thickness of the pipeline wall and, for that reason, just how much pressure it will hold. In most aquaculture applications, Schedule 40 is used. The main reason to utilize Schedule 80 is if it is necessary in your area for particular applications but it can also be used on cold water loops to help insulate. Schedule 80 is ranked at no less than 200 psi at 73 degrees F (approximately 2 inches) and is typically Gray (similar to the Schedule 40 pipeline used for electrical channel). The outside diameter (O.D.) is the same as Schedule 120 and 40, but the within diameter (I.D.) is smaller sized. Backed by over 40 years of both item and procedure development experience, Spears have turneded into one of the leading manufacturers of thermoplastic valves, fittings, and piping system parts. Spears broad product line provides a complete option of 1/8-inch through 12-inch injection built fittings and made fittings through 48-inch, lots of specialty products, and a complete match of manual and mechanically actuated thermoplastic valves in a multitude of types, sizes, and setups.
