COVNA HK60-D Cast Iron Wafer Electric Actuator Butterfly Valve
COVNA Motor Operated Wafer Butterfly Valve With Actuator:
Advantages include wide range of sizes, long life, and energy efficiency. Low torque required is 50N.m or 4000N.m. Flow control is excellent with the quarter turn design achieving it in one quarter of a turn. Products include switch type, intelligent actuators, regulating type, and all ensure full two way tight shut off. During pressure testing, bubbles are prevented from leaking through tight seal and pressure drop is reduced using steam-line disc. The design can also be altered to allow automated operation easily. Connection forms offered include Spec, Wafer, Lug, Tri Clamp, Flange-end with +/-10% rigidity. Default port size is between 2 to 24 inches but meets special requests for customized size to adjust for different needs.
