Technical Information Fig No. 116 'MF' Series

The Type ‘M’ Reducing Valve is hydraulically operated, single seated, piston actuated, diaphragm pilot controlled and spring regulated.

Automatically reduces higher and fluctuating inlet pressure to constant outlet pressures regardless of the flow demands.

The diaphragm pilot control closes when outlet setting is attained, diverting inlet pressure to the piston which closes the main valve at the rate determined by the flow restrictor. The "V-Ported" valve guide eliminates closing ‘slam.’ Under operating conditions the main valve establishes a throttling position as determined by the pilot control.
