Pneumatic butterfly valve type 240 FO PVC-U PN10

  Datasheet.pdf

Pneumatic butterfly valve type 240 FO in PVC-U is an automated quarter-turn valve engineered by Georg Fischer for chemical processing, water treatment, and industrial fluid handling. Featuring an integrated pneumatic actuator configured for fail-open (FO) operation across a 90 degrees control range, this unit ensures process safety by driving the disc to the open position upon air supply failure. Built with a robust wafer body from unplasticised polyvinylchloride (PVC-U), it provides reliable flow control and isolation for aggressive media up to a pressure rating of 10 bar (PN10) at 20 degrees Celsius.

The Type 240 FO complies with international face-to-face standards according to EN 558 and ISO 5752. Its wafer profile mounts between backing flanges across metric pipe sizes from d63 mm to d315 mm (DN50 to DN300). The universal body aligns with connecting dimensions according to ISO 7005 PN10, EN 1092 PN10, DIN 2501 PN10, ANSI/ASME B16.5 Class 150, and JIS B 2220. As an authorised Georg Fischer distributor, BigWeld supplies the Type 240 FO valve for reliable industrial automation.

Designed for maintenance-free operation, the valve eliminates metal contact with the process fluid, offering long service life in corrosive environments, acid-base dosing, and industrial cooling loops.
