A simple email template for your first valve enquiry
A fill-in-the-blanks enquiry email that gets a useful answer in one round instead of three. Copy it, replace the bracketed parts, delete what does not apply.
Most first enquiries are two lines long and cost three rounds of questions. The template below is six lines and usually costs none. Copy it, replace what is in brackets, and delete any line you genuinely cannot answer - an honest gap is more useful than a guess.
The template
Subject: Cylinder valve enquiry - [gas] - [quantity] pcs
Hello,
We are looking for a cylinder valve for [gas] service. Our cylinders work at [pressure, with the unit], and the current valve connects with [cylinder-side connection] on the cylinder and [outlet connection] on the outlet. [We need a nominal bore of X mm / The bore is not critical for us.] [A safety device is required by [whose standard] / No safety device is required.]
We would need about [quantity] pieces [per order / per quarter], delivered to [country].
[We do not have a model designation. Photographs of our current valve are attached: the whole valve from two sides, the markings on the body, and both connections.]
Could you tell us which exact models fit, and what you would need confirmed before quoting?
Best regards, [name, company]
Why each line is there
The subject line - Gas and quantity are what route an enquiry to the right desk.
The unit, every time - MPa, bar and Psi all appear in valve records. Naming the unit removes a whole class of misunderstanding.
Both connections, or photographs instead - If you do not have the designations, photographs along the axis of each thread are better than a description.
Whose standard requires the safety device - Your own filling standard, the cylinder standard and a customer requirement are different answers.
The closing question - Asking what needs confirming invites the supplier to tell you what they do not yet know, instead of quietly assuming it.
What not to write
One thing to leave out: "please quote your best equivalent to [model]". An equivalence is a claim that needs its own evidence - connection orientation, material compatibility and certification scope are confirmed per exact model - and asking for one as an opening move hides the requirement you actually have.
