Product Description

First, YQ98001 type filter piston type adjustable pressure reducing valve -- principle:
YQ98001 type filter piston adjustable pressure reducing valve by the comparison tube to transfer the pressure difference signal to the flow pilot valve, the limiting valve and the needle valve to perform two control control. To control the pressure on the main valve piston chamber. Adjust the regulation of the pile plug through the restrictor pilot valve. Make the flow rate after the valve reach the set value; The lower cavity of the piston is connected with the downstream orifice. It can be closed by flushing the valve, and the pressure difference between the two ends of the main valve is the valve opening. Closed drive energy. Mainly used for air conditioning. Water supply and drainage. Fire and all kinds of industrial and mining enterprises and other water supply pipe network port need to filter and control the flow of places and conditions. The upstream pressure can be reduced to the downstream pressure set, no matter how to change the upstream pressure and flow, the pre-set downstream pressure can remain unchanged.
                                                                                       

Second, YQ98001 type filter piston type adjustable pressure reducing valve -- connection size:


 

DN	50	65	80	100	125	150	200	250	300	350	400
L	250	280	335	380	425	480	750	660	740	810	860

 
Three, YQ98001 type filter piston type adjustable pressure reducing valve -- features:
1. Pitot tube transmits pressure signal to extremely sensitive restrictor valve, no orifice orifice throttling, no pressure loss, energy saving.
2. The current limiting pilot valve has a very sensitive spring to adjust the flow, the operation is simple and accurate.
3. Y-shaped wide-body valve chamber, small flow resistance. Strong anti-cavitation.
Daily medium pressure control, no need for external drive source.5.
The main valve body inlet flange and seat between the filter, saving investment costs and installation costs.6
. Internal and external surfaces are sprayed with huihui environmental protection coating. Ensure the product corrosion prevention and safety.

6. YQ98001 type filter piston type adjustable pressure reducing valve -- Installation method and connection requirements:
First, according to the pressure reduction characteristics of the working condition, the gate valve must be installed in front of the valve;
Second, to facilitate the maintenance of the valve in the future. Flexible winding soft connection must be installed after the pressure reducing valve;
Three 'the best installation mode is horizontal, other directions can also be accepted;
Four, must leave enough working space to facilitate maintenance;
5. Effective measures shall be adopted when hoisting. The valve lifting ring can also be used.
