Seawater hydrants valve includes shut-off

摘要

A Pressure reducing valve for seawater fire hydrants has been introduced by Boiswood. The DM668E from Mankenberg is a diaphragm-controlled spring loaded valve for medium flow rates and combines shut-off and pressure reducing functions.Intended for use on offshore installations, such as oil and gas platforms, this new medium-controlled valve offers accurate control while being easy to install and maintain. The pressure downstream of the valve is controlled without the use of pneumatic or electrical control elements.
