3-Wege-Steuerventil

1. Introduction: ZXQ and ZXX series pneumatic diaphragm tee regulating valve adopts double spool upper and lower guide structure and multi-spring actuator. With valve body in cross joint structure, that is 1-in and 2-out (split type) or 2-in and 1-out (confluent type), the performance of temperature increasing and decreasing when fluid is blending or fluid flow unequal splitting can be achieved to meet the requirements of real working condition. The valve body features impact structure, light weight, flexible action, small pressure drop, large valve capacity, accurate flow characteristics, easy maintenance and other advantages. It applies to various working conditions, in particular, being suitable to the temperature control of heat exchanger system in petroleum industry and the automatic control in other industries. 2. Features: The valve works smoothly because fluid is flowing away from the spool. Besides bush guiding of upper valve cap, the side face of spool and the internal surface of valve seat also have guiding effect, which features large guiding area and reliable performance. By adopting multi-spring structure, the height and the weight of the actuator are both reduced by 30%.
