Globe valves

Valve, also called cut-off doors, is the most widely used as a valve, which are popular is because the process of opening and closing the sealing surface friction between the small, more durable, highly open small easy to manufacture, easy maintenance, not only suitable for low pressure, but also for high pressure.
Valve closed principle is to rely on bar pressure valve, the valve sealing surface and valve seat sealing surface in close fit to prevent the media flow.
One-way valve can only medium flow direction when installing. Valve gate structure is longer than the same time, large fluid resistance, long runs, sealing reliability is not strong.
: Valve advantages
A simple structure, manufacture and maintenance more convenient.
2, the stroke is small, open and close a short time.
3, sealing, and sealing surface between the friction force is small, longer life expectancy.
