ACTUATED VALVES SERIES RV-FLUID

Actuated valves in the RV-FLUID series consist of a pneumatic rotary actuator series R4 that controls a ball or a butterfly valve. Ball valves come in the 2- and the 3-way version, with nickel-plated brass or stainless steel body. Butterfly valves are available with a painted cast iron body and nickel-plated cast iron lens. The actuator is the rack-and-pinion type, with an aluminium body processed with thick hard anodization and powder-coated heads. It is available in the single-acting version or double-acting version, and allows the valve to rotate by 90 degrees with limit switch adjustment on both ends. Operation is the pinion-and-rack type, a technology characterised by the constant supply of torque during the entire rotation. The control valve can be applied either directly to the actuator thanks to the NAMUR VDI\VDE-3845 interface or remotely using the threaded connections on the body.A specific accessory (switch box) can be installed on the actuator to detect the limit switch positions.
