Question and Answer

Question: I'm considering the use of a 2" 1500# RTJ D Type DB&B c/w sample probe. Can you please advise the size range of the NPT threaded outlets available. Also if possible could you forward a dimensioned detai drawing.

Answer:

It is dependant on the Bore size. On our 10mm Bore DBB Valves we could offer a 3/4" and ½" and 1" NPT outlet.

Question: Do you have an ordering guide for model numbers for sample double block and bleed valves (chemical injection quills / sample connections involving dbb)?

Answer:

We could send a copy of our catalogues, they have a part numbering guide for each product. If you contact our sales team on sales@valves.co.uk or by calling +44 (0) 1565 632 636, we will be happy to send you the relevant catalogues.
