PRV with Dual Certification - ASME & CE

PRV with Dual Certification - ASME & CE

PRV with Dual Certification - ASME & CE

(OP)
Hello all,

I need your help with finding a pressure relief valve for steam application that has dual certificate - ASME ("UV" Stamped) and CE (PED 2014/68/EU).

Some general information regarding the PRV I am looking for:
Approvals: ASME/NB certified "UV" stamped, CRN, "CE" marked.
Inlet Size: 1/4" NPT.
Set Pressure: 40psi/2.8 Bar.

I've been trying to find PRVs from "HEROSE", "Kingston" and "Apollo" but none of them match me needs.

Any help will be much apricated

RE: PRV with Dual Certification - ASME & CE

Try Teledyne Farris, Dresser/Consolidated, Kunkle, Crosby, Anderson-Greenwood, Leser, Sempell, and Mercer.

Good Luck,
Latexman

RE: PRV with Dual Certification - ASME & CE

Most established ASME PRV manufacturers have certified their products to PED.

Your main problem is the inlet size of 1/4"

Note that if liquid application, the smallest permissible inlet size following ASME XIII is 1/2".

Brands to try are Kunkle (Emerson), Bailey (Emerson), Seetru (UK)

*** Per ISO-4126, the generic term 'Safety Valve' is used regardless of application or design ***

*** 'Pressure-relief Valve' is the equivalent ASME/API term ***

The Obturator, Thanks for you response.
It is steam application, indeed, the 1/4" is an issue here.
Kunkle and Bailey don't do 1/4" PRV.
Seetru has 1/4" but only CE marked.

RE: PRV with Dual Certification - ASME & CE

There are limited PRV's in size 1/4" but not for steam. The ones that do exist are mainly for steam loco model makers and/or espresso machines which don't generally have ASME or PED. What is your application and why the need for both ASME and PED?

Application: small sterilizers machines (autoclaves)
I need both ASME and PED because holding one type of inventory is cheaper and my company sells worldwide.

RE: PRV with Dual Certification - ASME & CE

In that case, it may be worth your while to review both the scope of ASME and PED to determine if equipment such as autoclaves are actually covered.

I seem to recall PED not including equipment such as 'simple pressure vessels' of a certain volume.

You best tackle this with your engineering/QA people to determine whether ASME and PED apply.

Failing that, your best solution would be get a manufacturer with existing ASME and get them to obtain PED certification for the selected size/type of PRV based on the potential of future business of sales of your autoclaves. Either that or consider a larger size PRV and/or bursting disc.

Exactly what I did, waiting for an answer.

Thanks.
