Product description
BSPF Series Dynamic Balance Electric Regulation Valve with a new design concept, it is widely used in the central air conditioning control.The transport flow in any open position is the single and constant ;.the valve opening changed only by the standard control signals control.not affected by system pressure fluctuations;flow characteristics curve is in accordance with the ideal flow characteristics curve;good regulation characteristics.
Product features
Valve shut off the pressure difference, leakage is very small;
Body material: ductile iron, surface for rust treatment, the appearance of fine;
By using a straight stroke adjustment type driver, the flow rate is accurately output: the percentage of the curve or the linear curve (the setting of the code switch on the driver);
Dynamic balancing part: the balanced design of the bellows, the valve before the pressure fluctuations can easily achieve dynamic balance;
Drive control signal: 0 (2) -10VDC, 0 (4) -20mA (free setting of the code on the driver);
Drive valve position feedback signal: 0 (2) -10VDC, 0 (4) -20mA (open on the drive).
