Product Details

ZXG/ZDLG/ZAZG series Cage guided control valve is singled seat with high performance, which is suitable for the place where has flash vaporization and cavitations generated by the high differential pressure, solid cages and prevent the body from the damage of flash vaporization and cavitations. The fluid channel is streamlined by S shape with low pressure loss, high capacity, wide regulating range. The plug features big guiding area and good vibration resistance. The control valve is equipped with mult-spring diaphragm actuator and compact in structure as well as big in output force. 



1. Reduced trim can be chosen to provide wide capabilities for site applications 
2. Balanced trims are suitable for high pressure drop and shutoff
3. Hardened trims to handle high pressure drop applications
4. Bellows seal for special medium
5. Extended bonnet for low temperature 
6. Finned bonnet for high temperature
7. Higher maximum valve flow coefficients 
8. Bigger body volume to reduce cavitations
