Valve Characteristics

1)Y-pattern forged body, little flow resistance, high CV value.

2)Disc with throttle piece, effectively protecting the sealing surface, extend valve life.

3)Disc & seat sealing surface are treated by special processing for anti-cavitation, anti-erosion.

4)Two guide rings in disc ensure stem bear balanced force, flexible movement to avoid jammed phenomenon.

5)High-quality flexible graphite packing GARLOCK imported, good chemical property and flexibility, low friction, long service life.

6)Fast switching speed, generally 3-5 seconds, effectively protect the system security, greatly reduce the time of the sealing surface eroded by the media.

7)Bonnet heatsink, sufficient cooling to protect pneumatic actuators and solenoid valve not affected by the high temperature. Chamber gasket clip wire the high mesh flexible graphite pad, better sealing performance and reliability than the average flexible graphite.


Application
