RE: Gate valve - Body with socket weld tap at location D



Ask end user to get a copy of the (valid) specification (drawing/ description) he is referring to.

It is a general problem that end users or purchasers give 'abbreviated' or not full specification. Well-known and long experienced suppliers will read and understand, but the hard fact is that the text is missing 'something'.

A formulation (for instance) as below should do the trick:

Our QA system requires that full technical description is in our hands before we can offer. In your description we do not find any reference to relevant documentation (or detailed description etc) for xxxxx.

Please advice soonest.

See ASME B16.34-2009 Figure 1 (a) on page 14.

You will need to clarify what size socket is required, or select a size based on the NPS 10 valve size, and tell your customer what you are supplying.
