Series 81 – Direct Use Regulators

Description

The 81 series direct-use regulators are designed for high-pressure service and large loads such as factories, office buildings, restaurants, etc. Output pressures range from 5 to 20 psig (psi pressure). A high pressure regulator, usually with the help of another regulator, reduces the tank pressure to the average pressure level for use. It is also used as a last-stage service in certain applications.
