Name：D100 self-operated pressure regulating valve
D100 self-operated pressure regulating valve is an energy-efficient auto modulation device which regulate according media pressure and pressure change, take it as power and move as pre-set ＆#118alue without external power supply. It integrated with inspect, control and execute functions, to be an independent instrument control system.
This product is combined of low flow resistance single valve (sleeve), bellows balance piece (sleeve) and actuator. It’s new range product which confirm to national standard, the features are as following:
1.energy-efficient auto control system without external power supply, low equipment cost, suitable for explosion proof environment
2.Simple structure, easy maintenance.
3.Set position can be adjusted and adjustable range is wide, easy for user continuously adjusts in the set range.
4.Comparing with diaphragm type, cylinder type has faster dynamic response speed, higher accuracy and bigger adjustable ratio.
5.Pressure balance device provides a rapid response, accurate control and large allowing differential pressure.
This product has features like no need of power supply, Simple structure, easy maintenance & operation, very suitable for city heat& gas supply, gas supply and occasion which no power/gas supply but need to control liquid & gas pressure.
According to foreign media reported that this product will help to improve energy-efficient to 30%-40% when installed in city heating system.
