Belimo Butterfly Valve DN65/PN16 Wafer 24VAC/DC Open/Close GGG40 EPDM IP54 ISO 5211 35s 40Nm D665N/GRC24A-5

This Belimo butterfly valve is offered in combination with an open/close electrical actuator. The actuator can turn the valve from 0-90 degrees in a time of 35 seconds and requires a supply voltage of 24 V AC/DC. The electrical actuator comes with a visual positioning indicator to clearly see valve position. The butterfly valve has a wafer type flange for connecting it to the piping, a nominal diameter of DN 65, and is rated up to 16 bar (232 psi) for non-hazardous fluids. Please note that the maximum pressure may deviate based on the medium type, so carefully check the datasheet. The butterfly valve has a cast iron GGG 40 housing, and an EPDM seal. The valve is suitable for media temperatures between -20 and 120 °C (-4 and 248 °F). The actuator has an IP54 degree of protection and is suitable for an environmental temperature of -30 to 50 °C (-22 and 122 °F). The actuator can be mounted on the valve via the ISO 5211 flange. Before connecting the actuator, please read the manual carefully.

The actuator, equipped with overload protection, doesn't need limit switches and will stop automatically when the end stop is reached. Manual override is possible using a push-button, which disengages the gear train as long as the button is pressed or remains locked. The actuator can be directly mounted on the rotary or butterfly valve with a mounting flange. The mounting orientation relative to the valve can be selected in 90° increments. The rotation angle can be adjusted with mechanical end stops.

Pros:

• No risk of water hammer due to slow closing (35 s)
• The components are interchangeable and can be replaced individually if needed
• High Kv-value because the fluid flows in a straight line
• Suitable for viscous media
