Request For Piping Valves Data Sheets 2

[VITALIS1977]

Dear all,
I'm currently trying to gather information in order to create detailed data sheets per piping valve type.
A lot of engineering companies provide valve specifications but in their effort to use a common format to cover all types of valves, these are sometimes purely described (depending on the company of cource). Could someone provide independent(or direct me to the best source) data sheet formats targeting to the features that describe each valve type best?
Thank you in advance.
Elias

Such a broad objective will get you a infinite amount of information!

Before you start collecting it, you might want to narrow down your efforts by deciding the valve types you want to work with, the design and testing standards, maybe a size and pressure range, and the main body/trim materials you aim to work with.

You'll inevitably find that there's a reason why the catalogues you've seen are so generic, and the reason is that this is the only way of reducing the possible combinations of valve type x design standard x testing standard x range of nominal bores, range of pressure classes x end connection x body material x trim material, only to mention a few....

I work with valves in exotic alloys at alloy-valves.com. This is me on Twitter and LinkedIn. Let's connect!

The key is to look at the valve standard you wish to follow then find out which items need to be defined by the customer (you) or further added to.

The API standards are quite good in that regard and normally include a start point for the key information required from a purchaser in the form of a data sheet. In terms of format it is probably the baest one to start with and then ad dlines as required.

The issue is that each engineering company / oil company gradually adds lots of additional requirements, tests and often superfluous data because it is required for one particular project and gets left there for the next one...

vendors of particular types of valves will often supply blank data sheets which you could use as input data, but I wouldn't try to have different ones for each type of valve, just have some general data about the service, fluid, tag no, that sort of thing, then different sections dealing with each type of valve.

My motto: Learn something new every day

Also: There's usually a good reason why everyone does it that way

Go here for a sample of the issues you need to include in making your own company Valve Purchase Data Sheet.

Sometimes its possible to do all the right things and still get bad results

When the valve data sheet is constructed to be a norm for valves to be allowed offered, almost every second company stray from the main road and end in the ditch on one or the other side: either specifying way to much or way to little.

A common comment from bidders side is often that 'this data sheet is giving everything you need, except the information making it possible to give an offer.*

To the more serious side: The task of making a good valve data-sheet is more difficult than often presumed.

Do as the previous advicors say: define what you actually want to use. This is usually the traditional way a (oil?) company with a 'standard' use of 'standard' valves will want to limit and narrow alternatives down to what they 'always have done' and are sure qualifies.

For all others, searching new constructions, materials and exploring new ways or applications for valves:
- Open for alternative types of valves, materials and solutions and qualities in the inquiries.
- Make the datasheet after the valves are finally selected, mainly for maintenance, spareparts and refurbishment use.

Good Luck!
