Wafer butterfly valves are commonly used in the oil and gas industry for the following applications:
Pipeline isolation and throttling
Wafer butterfly valves are used to isolate sections of pipelines or control the flow rate in pipelines. They provide an economic solution for frequent operation and tight shutoff requirements.
Tank farm isolations
Wafer butterfly valves are ideal for isolating storage tanks from the pipeline network. They can handle the large diameters commonly found in tank farm applications.
Pigging operations
Wafer butterfly valves are used to allow the passage of pipeline pigs for cleaning and inspection operations. They need to provide a tight shutoff after the pigging operation is complete.
Emergency shutdown systems
Wafer butterfly valves are often used in emergency shutdown systems to quickly isolate equipment or pipelines if needed. Fast-acting valves with tight shutoff are required for these applications.
Metering and sampling
Smaller wafer butterfly valves are used for controlling the flow to meters, samplers and other instrumentation. Precise throttling control and minimal leakage are important for these applications.
Compressor isolations
Large wafer butterfly valves are commonly used to isolate compressors from the main gas pipeline for maintenance and repair operations. Compact, lightweight valves that can handle high pressures are required.
Condensate stabilisation
Wafer butterfly valves control and isolate the flow of condensate liquids in gas processing equipment like stabilisation columns and fractionation units. Corrosion-resistant materials are often specified for these applications.
China wafer butterfly valve suppliers give main applications are pipeline isolation and control, emergency shutdown, metering and sampling, compressor and tank farm isolation, pigging, and condensate handling. Wafer butterfly valves are well suited for the high-pressure, large-diameter, tight shutoff, and frequent operation requirements in oil and gas processing facilities.
