當前位置:首頁 >> >>Fine small pneumatic control valve

ZMAX pneumatic high caliber three shunt valve

關注次數:

ZMAX (Q) series of pneumatic diaphragm three valve dual spool upper and lower guide structure, equipped with multi spring actuator, valve for the four structures, namely one into two (shunt), two into a (confluent), so as to achieve the fluid mixing heating or cooling effect, or fluid from a shunt, meet the requirements of different conditions. The 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, 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.
The 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.
