200x Adjustable Pressure Reducing Valve Application: Water Treatment

We are customer centric entity, engaged in exporting an 200X adjustable pressure reducing valve in Botou, Hebei, China. Control the main valve of the fixed outlet pressure, not because of the main valve upstream inlet pressure changes, nor because of the main valve downstream outlet water change to change its outlet pressure. Can be used for domestic water supply. The hydraulic control valve is mainly used in fire fighting system and industrial water supply system. A

Installation:
1, the valve installation without direction, pay attention to the body arrow with the flow direction. A
2, the valve must be installed before the valve and the corresponding caliber filter, to ensure convenient maintenance and extend valve life. A
3, the installation must be very careful, so as to avoid external valve pipe damage. A
Debugging:
1, the valve clockwise, then counterclockwise to the 1 / 4 ring opening, the valve fully open.
2, adjust the pilot valve on the regulating screw, clockwise rotation to increase the pressure after the valve, counterclockwise to reduce, so as to achieve the set pressure. A
3, debugging, if there is "hunting vibration" phenomenon, at this time can adjust the opening of the needle valve. To reduce the opening frequency of main valve, eliminate "hunting vibration". A
4, in the adjustment process, if more than the required pressure value, should be counterclockwise adjustment lever back, and make the valve after decompression, and then re adjust.
