Watts-Radiant Valve Actuator, 4-wire 24V, 81001541 PZ656104
Valve Actuator for installation on the WattsRadiant Flowmeter Manifolds
This valve actuator is ideal for multiple small radiant zones. It provides on/off flow control to individual radiant circuits. It includes an indicator window to see whether the valve is fully open (black) or closed (red). Before installing, balance the flow by turning the adjustment valve under the blue cap.
Includes 4 wires to connect to the thermostat/controller and close an end switch.
Actuators are normally closed and will open when power is applied. Travel time for the actuator is approx. 90 seconds to close the end switch.
Compatible with older Watts actuators to replace then when they get stuck open or closed. Simply screw onto the Watts manifold. No plumbing required, and replacing an existing actuator does not depressurize the system.
Can be used with cast brass or stainless steel manifolds.
