POSITIONER/ACTUATOR CONTROL VALVE WITH SEPARATOR AND STEAM TRAP

1. Built-in cyclone separator and self-modulating free float steam trap provide dry, high-quality steam supply improving productivity and product quality for process applications.

2. Removal of condensate while valve is closed reduces scale adhesion and water hammer.

3. One combination I/P position/actuator (I/P positioned actuator) saves space and simplifies system layout, piping, and maintenance.

4. Top mounting of the I/P positioned actuator eliminates passerby damage and misadjustment associated with side-mount components.

5. Combined large-surface-area screen for trap and separator reduces cost and piping space.

6. Zero/span adjustment can be performed by simple dial rotation.7. Self-adjusting chevron packing minimizes seal leaks, stem wear, and

stiction/hysteresis problems.

1. The discharge capacity is the maximum continuous condensate discharge 11°F below saturated steam temperature.2. The differential pressure is the difference between the CV-COS inlet and its trap outlet pressure.

CAUTIONDO NOT use this product

under conditions that exceed maximum differential pressure, as condensate backup will occur!
