Introduction

Scope of the Manual

This manual provides instructions and parts lists for

67C Series instrument supply regulators. Instructions

and parts lists for other equipment mentioned in this

instruction manual, as well as for other 67C Series

regulators, are found in separate manuals.

Product Descriptions

The 67C Series direct-operated regulators are typically

used to provide constantly controlled, reduced

pressures to pneumatic and electro-pneumatic

controllers and other instruments. They are suitable for

most air or gas applications. Other applications include

providing reduced pressures to air chucks, air jets and

spray guns.

• The Types 67C and 67CS are the standard

instrumentsupplyregulatorswithoutalteror

internal relief.

• The Types 67CF and 67CFS are equipped with a

lterforremovingparticlesfromthesupplygas.

• The Types 67CR and 67CSR have an internal

relief valve with a soft seat for reliable shutoff with

no discernible leakage.

• TheTypes67CFRand67CFSRhavealterand

internal relief valve with a soft seat for reliable

shutoff with no discernible leakage.

Principle of Operation

Downstream pressure is registered internally on the

lower side of the diaphragm. When the downstream

pressure is at or above the set pressure, the valve plug

isheldagainsttheoriceandthereisnoowthrough

the regulator. When demand increases, downstream

pressure drops slightly allowing the spring to extend,

moving the stem down and the valve plug away from

theorice.Thisallowsowthroughtheregulator.
