Mark 53/54 Series

Differential, Jorlon Diaphragm

The Mark 53 and 54 Series transform challenging differential pressure control into reliable, repeatable operation. By maintaining a precise pressure differential between inlet and signal pressure, these valves enable sophisticated process control strategies – from maintaining consistent pressure drops across filters and strainers to managing complex reactor pressure profiles. When your process depends on maintaining exact pressure relationships, not just absolute pressures, these valves deliver the control intelligence you need.

The Mark 53 provides robust differential pressure control for standard applications, while the Mark 54's larger diaphragm minimizes pressure offset for ultra-precise control. This reduced offset means your actual operating pressure stays closer to setpoint across varying flow conditions – critical for sensitive processes where even minor pressure deviations impact product quality or yield. Both deliver identical flow capacity, so you're choosing precision level, not compromising throughput.

The Mark 54's capability for both differential and remote adjustment opens doors to sophisticated control schemes. Operators can fine-tune pressure relationships from the control room, adapting to changing process conditions without entering hazardous areas. The negative differential option enables unique applications like vacuum breaker control or maintaining precise suction pressures – capabilities that typically require complex instrumented systems.
