MODEL DRWP 150mm
●Operating Conditions:

●Basic Application:
Pilot operated valves are used in water reservoir tanks to keep the water level constant.
●Features:
1. The small-bore size of the pilot valve is advantageous in securing water reserve with a small air gap. 2. The water level of the storage tank can be easily adjusted by extending or shortening the length of the pipes. 3. The perforated stainless strainer lengthens diaphragm and seat life with its filtering and dynamic flow speed control. 4. Flow rate can be controlled from full open to full close by turning the adjustable spindle (especially useful in drought conditions). 5. Stainless steel seats avoid damage from dust much more effectively than bronze ones. 6. In comparison with side cover units, the top cover features easy maintenance of internal components. 7. Pilot operated valves are recommended when separately installing the pilot and main valves (even over a long distance). 8. Bronze prevents red rust contamination of potable water. 9. Optionally, pipe covering socket with headless allentkey screw and rubber bush are provided, using sus 304/316 Sch40 pipe with size of 15mm/1/2" OD=21.7mm pipes. (hole opening for pilot pipe penetrating is Min.35mm and finishing with silicon sealing)

●Operating Conditions:

●Basic Application:
DH units are used in water reservoir tanks to keep the water level constant.
●Features:
1. The DH unit is a pilot operated valve with sustaining valve function. 2. The perforated strainer lengthens diaphragm life. 3. Flow rate can be controlled from full open to full close by screwing the adjustable spindle (especially useful in drought conditions). 4. The back pressure setting bolt is fully covered by a brass metal cap to prevent unauthorized third parties from changing the setting. 5. Bronze prevents red rust contamination of potable water.

About pilot operated float valve with

Many water works utilities are facing the problem of "Peak Cut" and higher investment costs for distribution. The total consumption of water in big cities is increasing year by year. Water works utilities have to start planning for new pumps or new piping. Replacing equipment in main pump stations, enlarging pipes and changing the pipes to a larger bore is extremely expensive. But if water works utilities consider using Model DH, they'll find the cost of installing the DH unit is much cheaper than previous methods of investment. DH can fully support the water works utilities to solve the problem of "Peak-Cut". DH functions exaclty the same way as our body's blood-pressure control. Each DH becomes a nerve in the network of the water supply system.
Remark:
After installation of a DH unit, every pilot operated float valve must be changed to a DH unit, otherwise peak-cut problems will become worse. BRONZE V Float Valve With Sustaining Valve : Model DH/DHWP
Distribution is even. If the city-mains' pressure is high enough for distribution, 20mm pipe-sized tanks and 50mm pipe-sized tanks can get water smoothly and evenly. At normal night time hours the distribution situation is as above. Float Valve With Sustaining Valve : Model DH/DHWP
During peak time, the city-mains' pressure drops significantly. Water always goes towards the larger bore pipes or ground level at lower places. This causes uneven distribution. For example, the 20mm pipe only gets water after the 50mm pipe's tank becomes full of water. This means that occasionally, the 20mm pipe's tank might be empty! Float Valve With Sustaining Valve : Model DH/DHWP SOLUTION : INSTALL Model DH Pilot Operated Float Valve With Sustaining Valve. Water distribution is under control of DH. During peak time, city-mains' pressure drops significantly, but the DH unit starts to keep inlet pressure at the desired pressure by closing or opening the main valve. It's like the blood pressure control system in humans. Every DH unit continuously opens or closes the main valve regardless of the open or close state of the pilot until the inlet pressure becomes steady.
