I. Overview
XABQ (X) Pneumatic three-way regulating valve with XABQ pneumatic three-way merging control valve and XABThere are two structural types of X pneumatic three-way diversion regulating valve, which consists of a pneumatic thin film multi spring actuator and a three-way valve. The valve body has three channels, and the Q-type merging valve has two inlets and one outlet; The X-type diversion valve has one inlet and two outlets; Therefore, in certain situations, it can replace two regulating valves working simultaneously. The characteristics of this regulating valve are as follows:
Under normal circumstances, the direction of fluid action on the valve core is in the open state, so the operation of the valve is relatively stable.
The Z valve core is a cylindrical thin-walled structure that has a guiding effect on the inside of the valve seat. In addition, the valve stem and guide sleeve also have a guiding effect, so the guiding area is large and there will be no vibration Stable and reliable operation.
3. Equipped with a pneumatic thin film multi elastic actuator, it has a small volume, light weight, and high thrust.
Based on the above characteristics, this product can be used in industries such as petrochemicals, power plants, metallurgy, and high-end hotels to control simple ratios or adjust the cooling capacity of heat exchangers.
