| 1、Use |
| Suitable for the pipeline to transfer cogeneration,cogeneration,heating,oil,deoxygenized water and etc. |
| 2、Structure Features |
| The valve is composed by a full welding body together with the RPTFE sealing which ensures the valve can work well in case of there are imoutries or chemical substance.Floating ball structure and the flexible seat will ensure the ball and the sealing connects each other tightly.Evon when the pressure is not stable,the valve can also have a good sealing. The stem can be extended which is good for keeping the tempeture stable. |
