    Featured functions

    Quick assembly of the actuator

    The actuator is assembled on the valve by hand, without tool use, by moving the actuator vertically downwards (snap). Two positions of assembling the actuator to the valve is possible (2x180°). Slots must match the ribs on the valve neck. To remove the actuator from the valve, the metal pin must be pulled out to the unlocking position.

    Flow directions of the BVQ valve

    Designed for Seltron AQD actuators

    The 2-way BVQ-2100 valves are adjusted by AQD actuators for zone valves. Actuators controlled by 2-point signal are recomended for open/close aplications. Valves can also be used in combination with other actuators from the AQD family controled by 3-point or modulating control signal.
