Belimo Actuator 2&3-Point 230VAC 650Nm IP67 Terminals SPDT 38s F10/F12 SY6-230-3-T

This Belimo electrical actuator is designed for controlling quarter turn valves. The actuator delivers a torque of 650 Nm and can open/close the valve in 38 seconds. This actuator requires a supply voltage of 230 V AC and has a visual positioning indicator to clearly see the valve position. The actuator features two-point and three-point control. The actuator mounts to a quarter turn valve with an ISO 5211 F10 or F12 flanges. The actuator has a durable aluminium housing and has an IP67 protection rating. This actuator can operate within ambient temperatures between -30 and 40 °C (-22 and 104 °F). The actuator is equipped with 2 x SPDT auxiliary switches. A power cable can be easily attached via the terminal block.

Mechanical end stops confine the actuator between -2 ° and 92 °. The internal limit switches disrupt the motor's voltage supply. Additionally, a motor thermostat offers overload protection and interrupts the voltage supply if the actuator is operated outside the specified temperatures. An internal heater prevents the buildup of condensation. The integrated auxiliary switches feature a gold/silver coating that allows integration in circuits with either low currents (mA range) or larger currents (A range) as per the data sheet specifications. However, once larger currents have been applied, even just once, the contacts cannot be used in the milliampere range. The handwheel can close (turn clockwise) and open (turn counterclockwise) the butterfly valve. The handwheel remains stationary while the motor is running. The actuator is suitable for outdoor use and is protected against UV radiation, dirt/dust, rain/snow, and air humidity.

Pros:

• The ISO 5211 F10/F12 mounting flange fits many quarter-turn valves
• The actuator has the 2 x SPDT auxiliary switches
• Manual override
• Visual position indicator
• The actuator is suitable for outdoor use
• An internal heater prevents the buildup of condensation

Cons:

• The time to open/close of 38 s is slow for some applications
