Model M4100 Low Pressure Pneumatic Regulator

Model

M4100

The Model 4100A Pneumatic Precision

Regulator is a no bleed design regulator

that precisely controls a set pressure.

Features

• Sensitivity of 0.05" WC for Precision

Control in low pressure applications.

■ Large Relief Valve provides high exhaust

flows.

• Soft Valve seat minimizes air consumption.

• An Aspirator Tube compensates

upstream pressure build up underflow ExhaustValve

conditions.

Operating Principles

When you adjust the Range Screw to

a specific setpoint the Range Spring

exerts a downward force against the

top of the Control Diaphragm. This

downward force opens the Supply

Valve. Output pressure flows through

the Outlet Port and the Aspirator Tube

to the Control Chamber where it cre-

ates an upward force on the bottom of

the Control Diaphragm.

When the setpoint is reached, the

force of the Range Spring that acts on

the top of the Control Diaphragm bal-

ances with the force of output pres-

sure that acts on the bottom of the

Control Diaphragm and closes the

Supply Valve.

When the output pressure increases

above the setpoint, the Diaphragm

Assembly moves upward to close the

Supply Valve and open the Exhaust Valve,

and output pressure exhausts through the

Vent on the side of the unit until it reaches

the setpoint.
