Piston Type Axial Flow Regulating Valve Descriptions

Piston type axial flow regulating valve is mainly made up of valve body, piston, crank, connecting pod, energy dissipator, stem and seat. It’s metal and elastic double sealing structure, which is axisymmetric design. In this case that it can avoid throttling,   eliminate cavitation or vibration, in order to prevent the piping from damage. The piston type axial flow regulating valve is normally applicable to natural gas piping, coal gas piping, long distance water distribution piping line, water treatment plant, etc. Flowspec Luokai can manufacture and supply the piston type axial flow regulating valve with sizes of 2”~80” (DN50~DN2000mm).
