SP series digital lock balance valve is a valve for liquid pipeline hydraulic balance, it has the opening and opening the locking function. When the system flow changes, the installation of the valve, the flow of each branch of each user will proportionally increase or decrease during the initial adjustment, keep the flow distribution scheme, using the valve in heating and air conditioning water system, can achieve the heat saving energy-saving effect.
Product overview
Regulation performance - ideal;
■ good cut-off function;
■ accurate to the opening state of 1/10 circle display;
■ theory of flow characteristic curve as the percentage of properties such as curve;
■ theoretical characteristic curve for the percentage of curve, when the valve of the right degree in 0.3~0.5 actual curve is linear characteristics;
■ corresponding to each circle has flow coefficient is fixed, debugging as long as measured at both ends of the valve pressure difference, can conveniently calculate the flow through the valve
■ PTFE and silicone rubber seal, sealing performance and reliable;
■ no internal components use YIC18Ni9 or copper alloy manufacture, strong corrosion resistance, long service life;
■ inside the lifting stem, without reservation operation space.
