ZMAQ Mixing type 3 way control valve

ZMAQ Mixing type 3 way control valve Product introduction

　ZMAQ Mixing type 3 way control valve is dual spool upper and lower guide structure, ZMAQ Mixing type 3 way control valve is equipped with multi spring actuator, the flow direction is two into one (confluent), so as to achieve the fluid mixing heating or cooling effect, or fluid from a shunt, meet the requirements of different conditions. ZMAQ Mixing type 3 way control valve has the advantages of compact structure, in a light, sensitive action, small pressure drop loss, allowing the pressure high, new capacity is big, flow valve is accurate and convenient maintenance and so on, ZMAQ Mixing type 3 way control valve can be used in a variety of working conditions, temperature automatic control system and other industry control is especially suitable for the oil industry in the heat exchanger. ZMAQ Mixing type 3 way control valve has closed (divided) flow type, (points) flow high temperature type and other types of. Product nominal pressure level of a user PN1.6, 4, 6.4; the valve nominal diameter range of DN25~400; leakage class II grade, IV grade; flow is characteristic for linear and equal percentage. A variety of different specifications are available.
