Coupled with the short stroke of the unique sliding gate seat, The Jordan Valve Mark 50 is the most accurate and durable direct operated industrial back pressure regulator available in the market today. It is suitable for use in industries including chemical, petrochemical, oil and gas, pulp and paper, and more.
