This instruction manual provides installation, spring

adjustment, maintenance, and parts information for

the Type 119 control valve.



The Type 119 control valve (Figure 1) is used for

on-off or throttling control of noncorrosive or mildly

corrosive liquids and gases. It is designed to meet the

low-pressure liquid and gas application requirements

in many varied industries.

As loading pressure is applied to the Type 119 control

valve diaphragm, the disk holder is pulled off the

orice. As loading pressure is reduced, the opposing

spring force moves the disk holder toward the closed

position, resulting in spring-close action should a loss

of supply pressure occur.

The Specications table lists the specications for the

Type 119 control valve. Some of the specications for

a given control valve as it originally comes from the

factory are stamped on a nameplate (Figure 2) located

on the spring case ange.
