Tube end breathing valve

Dual guide(top and bottom)spool for valve stroke reduction of chatter and valve wear.
DETAILS:

The tube end breathing valve mainly includes:

Dual guide(top and bottom)spool for valve stroke reduction of chatter and valve wear.

Polyphenylene sulfide(PPS),a composite thermoplastic material used in the manufacture of valve seats and valve cores,has high chemical resistance,resistance to liquid and vapor adhesion,temperature(-45℃-260℃)and adhesion due to freezing of valve seat.

The valve core and seat assembly can be replaced on site without any tools or complicated procedures,and it does not need to be sent out for remanufacturing or replacing the whole valve(which can be maintained by internal maintenance personnel).

Characteristics and advantages of tube end breathing valve

The reasonable composite thermoplastic material is used in the manufacture of valve seat and valve core,which has high resistance to chemical attack,liquid and vapor adhesion,temperature(-45℃-260℃)and adhesion caused by seat freezing.

Double guide valve system can smooth the valve stroke and reduce valve wear during operation.

For the allowable leakage(1 scfh 90%set point per valve),the strict standard is exceeded and the set point accuracy is very high(+/-3%).

●field replaceable spool and seat assembly.

There are ANSI,DIN and Hg/t20592~20635-2009 flanges.
