Type 47 Pressure Reducing Valve

Model 47-02 pressure reducing valve can automatically reduce the inlet high pressure to the stable outlet low pressure in spite of the velocity of flow or the pressure variation. It is hydraulic pressure controlled by using a pilot controlled pressure adjustor to maintain the outlet pressure in a preset range. When the outlet pressure is over the preset range of the pressure reducing valve, the main valve and pilot will close to form a tight sealing.

Notice:
※When installing the valve, strongly request to leave enough space for maintenance. It is necessary to install the filter at the front section of the valve to avoid foreign materials to block the valve and affect the operation of the valve. ※King-Tech reserves the right to make any revisions on the valve model and size without prior notification.
※When making any design drawing, installation drawing or construction drawing, please do get our approved CAD with our signature, or we will not be responsible for any mistake.

Typical Application
 
 
 
 
 

●Big pressure reducing range
Suggest using several parallel 47-02 pressure reducing valves to reduce the pressure step by step to reach the requirement, so that it can avoid noise, vibration and air etching problems.
 
 
●Big flow rate range needed
Suggest using two parallel 47-02 pressure reducing valves. During big flow rate, two valves can operate together; during lower flow rate, the big size PRV will automatically shut down and the small size PRV continually provide needed flow rate. When presetting the valve adjustment range, preset the pressure value of small size 0.3 bar higher than that of big size of PRV.
