High-quality Bellows Sealed Globe Valve
GW Bellow foob ntiaj teb valve
Lub luag haujlwm ntawm bellows foob ntiaj teb valve yog kaw thiab tiv thaiv qhov nruab nrab los ntawm kev xau ntawm lub qia valve.Qhov qis kawg ntawm lub hauv siab yog txuas nrog lub valve qia los ntawm kev sib khi vuam, thiab sab sauv kawg yog txuas nrog lub caj pas los ntawm kev foob welding.Feem ntau, hlau kauv qhov txhab gasket yog ntsia nruab nrab ntawm lub caj pas thiab lub flange sab sauv los xyuas kom meej lub sealing.Lub hauv paus foob lub ntiaj teb valve muaj zog sealing kev ua tau zoo, thiab tsis tshua muaj to.
