Bellow valves zBEL

zBEL bellow valves do not require a constant supervision of their operation. They ensure complete external tightness, thanks to the gland zone, which is permanently separated from the flowing medium. ZETKAMA offer includes shut-off models as well as the ones with a throttle plug. In addition, for products made of cast steel, we offer a stop check version. The design allows the use of these valves in various types of installations.
