Usually used for on-off service, can not be used for throttling, used as cut-off media, do not apply to the regular opening and closing, and maintain the gate fully open or fully closed condition. Close the valve, the stem should be slightly turn (1/8 to 1/4 turn), in order to release the stem load, which makes the stem to expand slightly not stuck or damaging the valve and will not affect the sealing effect.

Wedge type flange gate valve:

Main features and uses

1 the structure is compact, the design is reasonable, the valve is rigid, the channel is smooth, the flow resistance coefficient is small.

2 the sealing surface is made of stainless steel or hard alloy, and the service life is long.

3 the flexible graphite packing is used, the seal is reliable, and the operation is light and flexible.

4 drive way to break up, electric, pneumatic, gear transmission.

5 widely used in petroleum, chemical, thermal power plant and other oil products, water vapor pipeline for the connection or cut off the pipeline in the medium of the opening and closing device.

High temperature and high pressure power station gate valve:

Applicable to the nominal pressure PN16.0Pa~32.0MPa, operating temperature ~ < 570 degrees C, the oil, chemical, hydraulic, thermal power plant system pipeline, cut off or connected to the pipeline medium.

Suitable medium for water, oil, steam, acid medium, etc., the operation mode is manual, gear, electric and so on.

Electric dark bar type knife gate valve:

The driving part adopts multi turn electric device used to drive and control the opening and closing of the valve, the operator can control the valve in the indoor remote control, also can be the scene of manual operation, also can be matched with a computer to realize automatic control. Widely used for drainage, heating, power plant, chemical industry, food, papermaking preparation, flowers, coal, mining and other projects, to meet the requirements of modern industrial automation.

Electric screw gate:

The channel has a full size, equivalent to the smooth pipe, flow capacity, flow resistance is small; with double seal on the downstream, no need of lubrication sealing, good sealing, high reliability; with fewer components; the design is novel, which can not only satisfy the requirements of process pipeline, and meet the user's operation and ease of maintenance requirements, to ensure long-term reliable operation of valves.
