Overview
The Jordan Valve 53-19 Mark 53 back pressure regulator is a precision differential pressure control valve designed for demanding industrial applications. This 1″ unit features a 316 stainless steel body and maintains a constant differential between inlet and diaphragm signal pressure across a 2–20 PSI operating range. The Mark 53 Series maintains inlet pressure at a set differential over the diaphragm signal pressure, delivering reliable upstream pressure regulation for process fluids, air, gas, and specialized media.
Key Features
- Differential pressure control: Maintains precise pressure differential between inlet and signal pressure, enabling sophisticated process control strategies
- Sliding gate seat technology: Jordan Valve’s differential regulators feature advanced sliding gate seat technology for straight-through flow, minimal turbulence, and tight shutoff
- 316 stainless steel construction for corrosion resistance and durability in aggressive media
- Compact 1″ threaded or flanged port design for standard industrial piping integration
- Field-adjustable 2–20 PSI setpoint range with easy access to adjustment mechanism
- FNPT or ANSI flange end connections compatible with standard piping systems
