當前位置：首頁 >> >>Gate Valve Series[usage]
Pneumatic valve and reliable performance, convenient operation and repair switch, petroleum, chemical, has been widely used in all kinds of marine sectors such as media control
[features]
1, pneumatic valve with pneumatic actuator and manual mechanism
2, the valve actuator with double cylinder structure, it is with a single cylinder type pneumatic valve, lifting force doubled
3, solved some valve single cylinder type pneumatic valve in the valve body wedge die and not open
4, a buffer mechanism, can effectively reduce the valve plate when the valve is closed by the piston down caused by the impact of the sealing surface and valve sealing surface wear, but also to avoid the Death Gate cards phenomenon
