Sliding Gate Regulators > Mark 57 Series




![]() |
The Mark 57 piloted operated back pressure regulator is designed to accurately control pressure to 100% of its rated flow capacity with only a small deviation from setpoint. The Mark 57 provides accuracy that approaches that of controller-operated valves and should be considered on most critical applications before other costly, more sophisticated instrumentation. The Mark 57 is part of the sliding gate regulator offering.As with all sliding gate products, a much shorter stroke than the standard globe or plug style valve is achieved. The shorter stroke combined with the action of the pilot valve creates a faster and more accurate response (less droop). |
