Testing of a 4″ A351 CF8M Bellows Seal Gate valve. Control valve motorized with actuator suitable for hazardous area classification zone 2 IIA t3 (Propane and 200ºC max surface temperature).
Bellows Seal Gate valves are a specialized type of gate valve designed to address specific challenges in industrial applications where leakage prevention is critical. These valves incorporate a bellows element, to create a hermetic seal around the valve stem. This bellows arrangement acts as a barrier, preventing the escape of fluids and gases from the system, and at the same time, it protects the stem from the external environment.
These valves find applications in sectors such as chemical processing, petrochemicals, pharmaceuticals, and other industries where the containment of fluids is critical. The ability to maintain a secure seal under varying temperatures and pressures makes bellows seal gate valves suitable for a wide range of operating conditions.
