Double water cooling type super high temperature butterfly valve adopts the high quality carbon steel and high temperature alloy steel, inner water cooling, the butterfly plate adopts the doublequality heat-resistant alloy steel, inner water cooling, flow switch valve outlet is arranged in thealarm function, also has two flow control valve in the import and export; can ensure the stable operation of the work of butterfly valves in high temperature conditions work, the highesttemperature can reach 1300 DEG C (instantaneous temperature less than 1400 DEG C), with less water consumption, high temperature resistance, small volume, flexible rotation, convenient use.

The purpose of the product:

This series of high-temperature butterfly valve is widely used in metallurgical, chemical, building materials, super high temperature gas pipelines in power plants and other industries in the high temperature gas medium, as a regulator or cut off; and various actuators (electric, pneumatic,worm) supporting the use of the different performance of the valve, which can realize the long-distance control and automatic regulation and cut off.

Product main parameters of electric device:

The product parts material:

Product installation and use:

1, the amount of water to adjust the inlet flow in two users at inlet and outlet valve, the outlet water temperature is less than or equal to 60 to 80 DEG C, and adjust the export flow velocity is larger than the inlet flow rate, at the same time to ensure that the valve plate in use before the cavity is filled with water.

2, to ensure enough cooling water cycle, when the flow switch alarm must be timely treatment.

3, when the manual operation, not in the hand wheel to increase the auxiliary lever, the hand wheelclockwise rotation for the valve opening, and closing of valve.

4, the valve can be installed horizontally or vertically, but the valve shaft should be horizontal andnon horizontal installation please specify included angle, the valve can be designed according tothe use requirements of manufacturing, electric device does not allow to start hanging, and non collision.

5, to ensure the smooth out water pipe system, at the same time, the water outlet pipe should be higher than the valve position.

6, the electric actuator technology parameters and wiring diagram of electric actuator instructionsplease refer to.

Annex please indicate (servo amplifier, electric actuator, control box with flange, etc.)

Note: the cooling water for the 0.3MPA soft water, the water temperature is less than or equal to 30DEG C, cooling water consumption (0.01 ~ 0.03) DNm3/h.
