CV-COS electro-pneumatic steam control valve

TLV are pleased to announce the general availability of the newly developed TLV CV-COS electro-pneumatic control valve, for steam applications

The bottom part of the valve features a built-in cyclone separator and free float steam trap.

Just like the famous Cospect pressure reducing valves, this provides dry, high-quality steam for process applications.

The top part of the valve features a compact pneumatic actuator with integrated I/P positioner.

This feature saves space and simplifies steam system layout, piping and maintenance.

Additionally, zero/span adjustment can be performed by simple dial rotation.

Features and Benefits.

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 positioner/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 minimises seal leaks, stem wear and stiction/hysteresis problems.
