CSDV - 1/2" NPT, 0.2 CV, 105 Degree Fahrenheit Condensate Sensing Drain Valve

Applications

The Armstrong CSDV is an automatic valve with a thermostatic wax filled capsule. The valve is designed for winterizing of steam tracing, instrument tracing, and condensate return line protection, or other processes requiring protection under 150° F (65° C).

Operation

The CSDV responds only to condensate temperature. After condensate cools to near set-point, the CSDV modulates flow to maintain a constant condensate discharge temperature. The CSDV is wide open at startup for rapid venting and initial heat up. CSDV valves are also self draining after shutdown to eliminate freeze damage. Typical set-points are 105° F, 125° F, 180° F, 210° F, and 240° F

Advantages

Since the CSDV discharges below steam temperature, the valve maintains a water seal which prevents live steam loss. However such operation may induce condensate corrosion in the process line, therefore, use should be limited to applications such as tracing lines which discharge to drain. The unique ram-type plug and seat provide reliable tight shut-off for longer periods than any other type available. A sized orifice and control port act together as a labyrinth restrictor to keep live steam loss to a minimum on failure. CSDV valves are 100% factory tested.
