Jordan Valve Mark 68G Globe-Style Pressure Regulator

Jordan Valve's Mark 68G is a self-operated, globe style pressure reducing valve. It offers high capacity, accurate regulation, and easy servicing for industrial pressure reducing applications. The bottom-entry design makes the Mark 68G simple to clean or repair. The diaphragm can be easily accessed from the top allowing some repairs to be conducted without removing the valve from the line.
