Product details

Mechanical VK2 volume flow controller for installation (independent of position) in ventilation ducts for supply air and exhaust air of ventilation systems. The rectangular casing with nominal sizes from 200 mm x 100 mm to 600 mm x 300 mm (W x H) and the control mechanism are made of galvanized sheet steel. The reference volume flow is adjusted via regulating device with rotary pointer, scale and lock. The volume flow range is between Vmin = 200m³/h and Vmax = 7000m³/h, the pressure range between 50 Pa and 1000 Pa. The adjustment can be done manually or optional by actuator.

Maintenance-free VK2 volume flow controllers are controllers for constant volume flows. They operate without an auxiliary power supply. The volume flow is maintained constant at variable pressures in the indicated pressure range with a variation of about ±5% to ±15%.
