ASME B16.34 Design & Manufacturing Compliance | Needle Valves – Perfect Engineers

What is ASME B16.34?

ASME B16.34 is the American Society of Mechanical Engineers’ standard titled:

“Valves – Flanged, Threaded, and Welding End”

It defines the design requirements for:

Wall thickness
Pressure-temperature ratings
Body and bonnet design
Material selection and marking
Testing and quality assurance

At Perfect Engineers, we incorporate ASME B16.34 guidelines into every stage of valve manufacturing, especially for high-pressure needle valves.

FAQs – ASME B16.34 Compliant Needle Valves

Are your needle valves designed to ASME B16.34?

Yes. All high-pressure SS and alloy needle valves follow ASME B16.34 for wall thickness, rating, and marking.

Do you offer pressure-temperature charts with valves?

Yes. Each product can be supplied with PT rating curves as per ASME B16.34 Annex C.

Can I get a valve with CE and ASME dual compliance?

Absolutely. We support dual compliance with CE, IBR, and ASME B16.34 based on project requirements.

Is third-party inspection available?

Yes. We offer TPI (BV, SGS, TUV, etc.) for design, dimensional, and pressure test validation.
