Press media operation upwardly.When the part adjacent with top cover is spacer member, whole work package disposing ways for being included in valve element
Do not limit.
Recess channels on the functor are non-engraved structure.
Valve element provided by the invention, with temperature control Absorption of Medium high-pressure medium liberated heat in decompression process, or it is height
Press medium to provide in the heat needed for decompression process, reduce pressure-reducing valve in itself because of effect of expanding with heat and contract with cold, improve heat exchange valve
The fit precision of core in the process of running.In addition, by controlling the flow of temperature control medium to control decompression process in pressure-reducing valve
In energy variation so that the outlet pressure of pressure-reducing valve a small range carry out intense adjustment.
