Description Material Performance Product Size Specifications

ZJHF (H) pneumatic three way valve has two kinds of structural forms of confluence and diversion. Thin walled cylinder valve structure using the window, and the spool side oriented, three-way valve can replace the two two valve and a three pass over and wait until the widely used in some occasions, two commonly used in heat exchangers of the regulation, can also be used for simple ratio adjustment. Nominal diameter and pressure is small, the mixing valve can be used for streaming applications, can be used interchangeably, but the nominal diameter greater than 80mm and larger shunt pressure situations, can not be used interchangeably.
Note: parameters are for reference only, or are not full. Valve can be used in accordance with the requirements of different pressure, material, diameter, drive, etc.. Specific please contact or online advisory contact.
