Best Practices for Steam Control Valve Installation
Step 2: Steam Line Drip Pocket
All steam control valves must have a condensate removal drip pocket piped upstream of the control valve. The drip pocket removes condensate from the steam line, preventing condensate from passing through the valve. This is essential because condensate permitted to pass through the valve will cause erosion and shorten the life of the valve. More importantly, when the steam control valve shuts off during low or non-production periods, the condensate drip pocket will remove accumulating condensate from the inlet of the steam control valve.
