        Bonomi N501S, 531S and 541S Valve Specification

        Valbia Electric Actuator Features
        • Valbia electric actuators are suitable for the automation of a great variety of ball and butterfly valves
        • The motor adjusts its speed at the load variations in order to consistently maintain the specified cycle time
        • The torque limiter and the heaters are both included in the standard version and are always automatically operating when the actuator is powered, to ensure a continuous protection against condensation and over-torque
        • The gear train is made of two steel and techno-polymer gear wheels, inserted in a strong die-cast aluminum structure and sustained by hardened steel pinions mounted on self-lubricating bushes, to provide a strong mechanical construction
        • The Valbia electric actuators are all designed with an ISO 5211 standard bottom connection pattern, in order to allow the direct mount of all ISO 5211 designed valves
        • ISO Pattern
        • The 85 series actuators feature a techno polymer enclosure and the 86 Series a metal  enclosure
        • Actuator Approvals: CE, UL & CSA
        • Auxiliary Limit Switches: n°2 STD (type SPOT)
        • Temperature range of 23°F to 131°F
        • Rotation 90°
        With Battery backup for Fail Safe Operation
        • This version allows for the the activation of the Battery as soon as the power supply is interrupted.
        • For this ON/OFF standard version:  Fail close, Fail open or complete the interrupted cycle.
        Special version with std (4-20mA or 0-10 V) or reverse (20-4mA or 10-0V) positioner
        • The modulating version can be controlled by a current (4-20 mA) or voltage (0-10V) command.
        • The proportional control allows a resolution command of 0.9°, with a positioning tolerance of less than 1% of the potentiometer full scale.
