Belimo 3-Way Globe Valve DN80 Flange 18mm Stroke Kvs90 24VAC/DC 35s 0-10V 1000N IP54 H779N/NVC24A-SZ-TPC

This is a Belimo 3-way globe valve with a coated cast iron housing and EPDM sealing. The bore diameter of the valve is DN 80 and the flange size is DN 80. The valve cone features an equipercentual characteristic according to VDI/VDE 2173, optimized within its opening range. The maximum pressure differential is 8 bar (116 psi). The valve can operate between 5 and 120 °C (41 to 248 °F). The Kv value of the valve is 90 m3/h, equivalent to a Cv-value of 104.13 gpm. The valve's stroke length is 18 mm. The actuator requires a supply voltage of 24 V AC/DC. The actuator utilizes a 0-10 V control type and provides position feedback, enabling precise control of its movements and accurate monitoring of its position within the specified voltage range. The actuator opens/closes the valve in 35 seconds. The actuator has an IP54 rating.

The actuator, equipped with overload protection, the actuator doesn't need limit switches and will stop automatically when the end stop is reached. Manual override is possible with a push-button, which disengages the gear train for as long as the button is pressed or locked. The stroke can be adjusted using a 4mm hexagon socket screw key inserted at the actuator's top, with the stroke shaft 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 can be controlled with a standard control signal of 0-10 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 default factory setting retracts the actuator stem.

Pros:

• Equal percentage flow characteristic, the bypass has a linear characteristic
