The feed water rotary control valve is suitable for the medium and low pressure boiler feed water pipelines and the high pressure heater water drain pipe. The area of ​​the window formed by rotating the cylindrical valve flap and the valve seat is changed, so as to achieve the purpose of adjusting the flow. The rotary angle of the feed water rotary control valve is 60°, which is indicated by the opening degree indicating plate above the regulating valve. Can be equipped with electric actuators for remote automation.
Water supply rotary control valve
Feedwater rotary control valve structure
Water supply rotary valve products main structural features:
1, mainly by the valve body, valve seat, valve, valve stem, valve cover, indicator board and other components;
2, the valve flow adjustment for the cylindrical valve and valve seat relative rotation to change the valve on the window area to achieve;
3, the valve's switching range. Indicated by the opening indicator plate above the valve, the indicated switch range is consistent with the valve switching range;
4. The rotary control valve is operated by a remote controller with a rotation angle of 60°C.

Storage installation notes
1, the valve should be stored in a dry room, the ends of the passage must be blocked. Do not stack and store.
2, long-term storage of the regulating valve should be regularly checked to remove dirt, in all moving parts and processing surfaces should be coated with rust-proof oil to prevent rust.
3, the valve should be installed on the horizontal pipeline, must be installed vertically. Stem upwards.
4. It must be installed according to the flow direction of the media indicated by the arrow in the figure.
