R505K - Belimo 3-way control ball valve, PN16

All in-stock Belimo ball Valves with iacs are delivered for free or within 1-2 days.

The Belimo R505K is a Valve used in HVAC applications (heating, ventilation, and air conditioning) systems as a control or shutdown Valve . in a circuit that is closed.

The Pressure Nominal of this Valve is PN 40.

This R505K Belimo Valve has a 3 port opening connection.

IACS has the most economical Belimo Valves for your system.

If you have any issues about size or installation, please refer to the Belimo custom datasheet above or contact iacs for further information.

Features

• Mode of operation The characterized control valve is operated by a rotary actuator. The actuator is controlled by a standard modulating or 3-point control system and move the ball of the valve – the throttling device – to the opening position dictated by the control signal. Open the ball valve counterclockwise and close it clockwise.
