Electric Sleeve Control Valve--Classic ZAZM Type
Original : 0.00
Product Details

Product features:

·ZAZM series sleeve control valve with DKZ electric actuator, easy for installation and maintenance, economic and applicable.

·If the user's request about the adjust accuracy is not too high, could choose ZAZM series sleeve seat control valve.

·The leakage of sleeve control valve is minimaland it can withstand greater pressure, so it is an ideal modulating valve.
