Manufactured from heavy gauge steel plate, each valve is complete with a 8-bladed rotor, equipped with hard-wearing neoprene rubber blades secured to the rotor shaft plate profiles, separated from the housing by rubber shaft seals.
Each valve is equipped with a close coupled geared reduction drive and rotation sensor plate.
As standard ‘BS’ rotor valves are ATEX approved to Cat. 2D and supplied with neoprene rubber blades for operational temperature range of -10°C to 70°C.
For higher temperature applications, 60° to 250°C, the rotor can be fitted with silicone rubber blades and for installations requiring Cat. 1D protection valves are available in an EXS format, working with the EXS control system.
