Flomatic has announced the release of its Heavy Duty Deep Well Check Valve Model 80MDW-VFD for use with variable-frequency drive (VFD) controlled submersible pumps or other conventional pumps. This valve is designed for well water use to support the weight of up to 3,300 feet of pipe and the well pump. The small OD valve body is constructed from strong carbon steel, similar in strength to API J55 tubing. Featuring a male inlet x female outlet body with eight round EU (External-Upset) Tubing threads 2 ⅜ through 4 ½ inches, or eight round male short casing threads x female long casing threads 4 ½ through 9 ⅝ inches.
In addition, a corrosion-resistant, stainless steel spring and stem combined with fusion-bonded epoxy coating inside and out allow for a longer service life. Model 80MDW-VFD comes standard with a ¾-inch break-off plug for easy servicing.
