[Valve features]

1, The valve is to rely on the stem pressure, so that the valve sealing surface and seat sealing surface close together, to prevent the flow of media. It belongs to forced seal type valve.

2, Valve medium flow "low prices" and "high low" in two, only the medium one-way flow direction when installing.

3, When the valve is opened, the opening height of the valve to reach the nominal diameter of the valve 25% to 30%, the flow has reached the maximum, that is, the cut-off valve has reached the fully open position.

4, The cut-off valve structure is simpler than the gate valve, manufacturing and maintenance are more convenient.

5, The sealing surface is not easy to wear and scrape, sealing good, open and close, the valve and the valve body sealing surface between the relative sliding, so that wear and tear are not serious, sealing performance, long service life.

6, When opening and closing, the valve stroke is small, so the cut-off valve height is smaller than the gate valve, but the length of the structure is longer than the gate valve.

7, Open and close torque is big, more laborious. The disc is always subject to erosion when fully open.

8, Large fluid resistance, because the valve inside the medium channel is tortuous, fluid resistance, power consumption.

[Adaptive condition]
ANSI Standard globe valve for the nominal pressure 150LB-2500LB, various working pipeline temperature of -29~550℃ oil, chemical, pharmaceutical, chemical, electric power industry and so on, cut off or connected piping media. Driving methods are manual, gear drive, electric, pneumatic and so on.
