ART.2824A
“Theoretical characteristic curve has equal percentage flow character. When the valve opens 30%¬50%,actual flow is linear.”
Clear, accuate opening display of valve. Accuracy is 1/10 opening circle. “It has opening lockable and mechanical memory function. Other people except professional staff can change its setting status.”
“There’s two small valve measuring pressure on the valve body.Working pressure difference and flow can be easily displayed by the intelligent instrument. So that the opening scale corresponding to the setted flow can be calculated. ”
“Local resistance coefficient of balancing valve is a bit high. We calculate its local resistance coefficient （ζ）when fully open according to its actual measuring flow character. ”
“No need to allow space for inner lifting stem. Inner parts are made of stainless steel, copper alloy, with good corrosion-insistent.”
We equip specialized intelligent instrument, for the use of debugging
