Pigging valve manufacturers
Pigging valves are used to launch or receive pipeline pigs for cleaning, drying, inspection, or product separation operations without requiring the removal of large pipeline sections. The valve provides a controlled entry point where the pig can be inserted into the pipeline and directed into the flow path. The design allows safe loading and sealing while maintaining containment of the process media.
Pigging valves are typically constructed with a full-bore flow path to ensure smooth pig passage without snagging or obstruction. The valve body often includes a side or top loading chamber with a closure mechanism to allow pig insertion and retrieval. Actuation may be manual or automated, depending on operating frequency, line pressure, and safety requirements.
Pigging valves are used in oil and gas transmission lines, chemical and petrochemical pipelines, multiproduct transfer systems, and food and beverage production lines where product contamination must be avoided. Proper selection considers pig type, pipeline diameter, pressure class, sealing arrangement, operating environment, and required safety interlocks during loading and unloading.
