Mark 6127 Series
Piloted, Liquid Pressure Regulating Valves
DESCRIPTION
Piloted, Liquid Pressure Regulating Valves
The Mark 6127 pressure-reducing valve is used in many applications worldwide. The primary function of the Mark 6127 is to reduce a greater upstream pressure to a lesser, more manageable downstream pressure, and operate without regard to either upstream supply or downstream demand. The valve is easily maintained without removal from the line.
