LD Series Low-Pressure Manual High-Purity Diaphragm Valve

LD Series Low-Pressure Manual High-Purity Diaphragm Valve is part of LGF’s high-purity gas flow-control component range for isolation or controlled flow within a high-purity gas path. The low-pressure manual high-purity diaphragm valve configuration should be compared with the specified gas, pressure and flow before it is added to the equipment schedule.

Technical details from the product listing

316L VIM-VAR stainless steel body material for ultrahigh-purity applications.
The inner surface roughness can reach Ra 5 μin, and the flow channel can be completely cleaned.
Hastelloy C-22 or cobalt-based superalloys (UNS R30003) material for strength and corrosion resistance.

What to confirm for your laboratory gas system

Confirm the exact configuration and ordering code against the current product drawing before purchase. Selection depends on the complete gas path, the operating conditions and the installation interface.

Gas compatibility and wetted materials
Operating pressure and temperature
Actuation and fail position where applicable
End connection and leak-test requirement

For an application-specific quotation, provide the gas or media, source condition, target pressure and flow, end connection and project location. Review the related selection and system guidance, then send LGF your specification.
