Pressure reducing valve VLM PIETRO FIORENTINI Vietnam

Introducing VLM PIETRO FIORENTINI Vietnam Pressure Reducing Valve

Pietro Fiorentini's VLM valve is a regulating and bypassing  device   characterized by a soft gasket on the valve seat for better tightness and a balanced shutter for easier opening and closing. The inlet body is suitable for flange joints.

This equipment is mainly used in high pressure transmission systems and in medium pressure gas distribution networks and it is suitable for use with natural gas and non-corrosive gas liquids that have been treated previous reason.
