DF-A magnetic valves(pic1)
DF-A magnetic valve(pic2)
applicable medium： low pressure steam,water,gas,oil,gas.coalgas
products function
apply to piperoad switch with medium as boilingwater, low pressure steam,gas,coalgas,oil to realize automatic control.
structure feature
1, direct acting -style open valve structure, without pressure can also open valve, low pressure with large flow.
2, use high temperature resistant materials to produce diaphragm, especially suitable for low pressure steam pipe media switching, cost is low.
3 and the body USES brass hot forging shape, inner stainless steel structure, small volume.
Special supply
1. if flange connecting is need, can match standard flange.
2. Material: cast steel.
3. for 0.25 Mpa, medium, and the temperature - 5 ~ 180 degrees.
4. such as used in vacuum, olease put forward in order, applicable vacuum is 0～10-5Torr
