22 - 500 Psig (1.5 – 34.5 Bar)
Description
LCV
The Series LCV Liquid Cylinder Pressure Control/Relief Valve
is designed exclusively for use on DOT 4L Cryogenic Liquid
Cylinders. The LCV dramatically reduces the noise associated
with traditional cylinder relief device discharge. Under normal
operating conditions, the LCV optimizes cylinder performance
by venting only what is required to maintain cylinder pressure in
a tight band. In the event that circumstances demand, the LCV
has adequate flow capacity to ensure safety, meeting all
industry and regulatory requirements.
