Belimo Manifold 12 x Zone Valves 24VAC/DC 75s 2-10V 1Nm IP40 EM-ECQ-12F/CQ24A-SR

This is an electrical actuated Belimo manifold zone valve with a brass housing and sealing. The bore diameter of the valve is This valve withstands pressure up to 6 bar (87 psi). The valve can operate between 2 to 70 °C (36 to 158 °F). The actuator requires a supply voltage of 24 V AC/DC. The modulating actuator is requires a 2-10 V input and offers position feedback, ensuring precise control over its operation and accurate monitoring of its position within the designated voltage range. The actuator opens/closes the valve in 75 seconds. There are 12 valves in a manifold block. The actuator has an IP40 rating.

The actuator, equipped with overload protection, the actuator doesn't need limit switches and will stop automatically when the end stop is reached. Remove the actuator by clicking it out, and then use the actuator to rotate the valve spindle. The actuator can be hand-mounted onto the valve without requiring tools. Just ensure only vertical movements (Caution!). The pins should align with the flange holes. The mounting orientation can be configured in 180° increments in relation to the valve. The actuator's rotation angle can be adjusted in increments of 2.5° using a clip. This feature is used for setting the valve's maximum flow rate. The actuator can be controlled with a standard control signal of 2-10 V and moves to the position dictated by the control signal. Voltage measurement is employed both for visually displaying the valve position within the 0.5% to 100% range and as a control signal for other actuators. The rotation angle can be adjusted with mechanical end stops.

Pros:

• This modulating actuator can position the valve anywhere between 0-90 degrees with a control signal of 2-10 V
• Manual override
• The actuator is overload protected
• Visual position indicator

Cons:

• The time to open/close of 75 s is slow for some applications
