Belimo Globe Valve 30mm Flange DN100 Kvs145 100-240VAC Fail-Safe 150s 3-point 2000N IP54 H6100R/AVK230A-3

This is a 2-way globe valve with a coated cast iron housing and EPDM sealing. The bore diameter of the valve is DN 100 and the flange size is DN 100. The valve cone's profile determines the equal percentage flow characteristic. The maximum pressure differential is 1.5 bar (21.8 psi). The valve can operate between 5 and 120 °C (41 to 248 °F). The Kv value of the valve is 145 m3/h, equivalent to a Cv-value of 167.76 gpm. The valves's stroke length is 30 mm. The actuator requires a supply voltage of 100-240 V AC. The actuator features three-point (open-close) control. The actuator opens/closes the valve in 150 seconds. The actuator has an IP54 rating. The actuator is equipped with a fail-safe (NC/NO) feature that ensures safe operation in the event of a power failure.

The actuator, equipped with overload protection, doesn't need limit switches and will stop automatically when the end stop is reached. During actuation, the stroke direction switch toggles the running direction in normal operation. However, it doesn't affect the preset fail-safe position. Manual override is possible with a push-button. The gear train disengages and the actuator decouples for the duration the button is pressed. Stroke adjustments can be made using a 5mm hexagon socket screw key inserted at the top of the actuator, with the stem extending when turned clockwise. The actuator can be directly mounted on the globe valve using form-fit hollow clamping jaws and it can be rotated 360° on the valve neck. The actuator moves the valve to the desired operating position simultaneously as the integrated capacitors charge. If the power supply is interrupted, the valve shifts to the chosen fail-safe position using the stored electrical energy. The default factory setting retracts the actuator stem. When shipping valve-actuator combinations, the motion direction is set based on the valve's closing point. The capacitor actuators require a pre-charging period to bring the capacitors to a usable voltage level. This ensures that, in case of a power failure, the actuator can move from its current position into the fail-safe position at any time. The rotary knob fail-safe position allows for adjustment of the preferred fail-safe position. The adjustment range is based on the actuator's maximum stroke height. In case of power failure, the actuator moves to the chosen fail-safe position considering a factory set bridging time of 2 seconds. Post-factory delivery, the actuator is fully discharged and requires about 20 seconds of pre-charging before initial setup to attain the necessary voltage level in the capacitors.

Pros:

• The integrated characterized disc ensures equal percentage flow, ideal for heating circuits
• The actuator is equipped with a fail-safe feature
