Description
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
insure safety, meeting all industry and regulatory requirements.
