The regulators are spring-loaded diaphragm-type regulators. The direct, on of air flow is indicated by on "In"
marklng next to the required port on the regulator. Air enters the air Inlet on the right-hand side and flows past the
spring-loaded valve disc which is held in the open position by the valve stem which extends up to the lower side of
the diaphragm. A spring-loaded spring retainer presses against the opposite side of the diaphragm. Air flows up
