non-return valve

[mcdue]

are desperately looking for a return valve like that in drawing (see attachment, item number 36): do you have suppliers I can address?

I have a quotation already in hand, but 600,00 € for something like this seem me pure madness: Am I wrong? in the background is only a valvolina of about 5 cm in stainless steel.

if you want me to detail how it is made I see to describe it and attach a hand sketch (or draw it to cad).

as always thanks to the prodigal.

depends on what you need to do with the unidirectional valve, the industry, fluid type, pressure and size, unidirectional closing technology.

Where are you going? I can help you a lot but I need some information

 

[mcdue]

the valve is mounted on the by-pass of a vacuum pump, the fluid are aspired vapours of the reactors and the thf is the only one among these vapours that can give problems: basically everything is solved by making it in stainless steel (the valvolina must be in aisi304 or aisi316).

I cannot tell you much about the pressures because they have never been monitored at that particular point, but I hypothesize they are never particularly high.

Anything else? (in case I see some reasoning to tell you more...)
