The bZZW self operated temperature control valve does not need additional energy, and uses the self energy of the regulated medium to realize the automatic temperature adjustment of the actuator products. Nominal pressure PN16, 40, 64; temperature regulation range from 0~270 degrees; temperature controller connection is G1 external thread; flange standard: PN16, 40 according to BG9113-8; PN64 according to JB79.2-94; PN16 is convex flange; PN40, 64 is concave convex flange, valve body is concave. Structural length according to GB12221-89 standard.

Independent temperature control valve structure variety, there are ZZWP, ZZWM single seat, sleeve control valve.

There are two options for heating regulation (B type) and for cooling regulation (K type).

It has a wide range of temperature setting, and is easy to adjust.

With over temperature and overload protection measures, safe and reliable.

The temperature setting is convenient and can be set continuously during the operation.

Six, installation matters:

Installation, use and maintenance:

(1) before installation, the pipeline should be strictly polluted, and the welding slag and other sundries should be removed, otherwise the valve will be seriously damaged.

(2) the temperature regulating valve should be installed vertically on the horizontal pipe, and the flow direction of the medium should be consistent with the arrow pointing on the valve body.

(3) in order to make the automatic control system or maintenance valve can continue to run, the bypass valve should be installed. The filter must be installed before the valve, the pressure gauge, and the thermometer installed near the sensor, which is convenient for on-site monitoring and temperature setting. See the picture below:

(4) the sensor must be immersed in the controlled medium and installed in horizontal or inclined upward direction.
