Butterfly check valves
APPLICATION
Butterfly check valves are protective devices in pipelines and pipe systems for transport and storage of liquid fluids. They are used to prevent the return flow of the working fluid, and the action of the butterfly check valves is automatic. They are most widely used in plants for obtaining, preparing and distributing water, in wastewater treatment plants, in utility facilities, in irrigation systems, in various plants of the chemical and petrochemical industry and in energy plants.
Butterfly check valves allow fluid flow in only one direction, so during installation, care should be taken that the direction of the arrow on the butterfly check valve housing corresponds to the direction of movement of the working fluid in a particular pipeline.
