• Polymer construction for corrosive

nnnn

resistance

nnnn

• Venturi design compensates downstream

nnnn

pressure droop under flowing conditions

nnnn

• Non-rising adjustment knob

nnnn

• Manifold mount capability

nnnn

• Push to connect fittings in all ports

nnnn

• Separate control chamber isolates the

nnnn

Diaphragm from the main flow to eliminate

nnnn

hunting and buzzing

nnnn

Operating Principles

nnnn

When the setpoint is reached, the upward

nnnn

force of the output pressure that acts on

nnnn

the bottom of the Diaphragm balances with

nnnn

the downward force that acts on the top of

nnnn

the Diaphragm. If the output pressure rises

nnnn

above the setpoint, the force that acts on

nnnn

the bottom of the Diaphragm moves the

nnnn

Diaphragm Assembly upward to close the

nnnn

Supply Valve and open the Relief Valve.

nnnn

Excess output pressure exhausts through the

nnnn

Vent in the unit until it reaches the setpoint.
