Mark 5108 Series
In many liquid piping systems, it is vital that line pressure is maintained within relatively narrow limits. Installed in the main flow line, the standard Mark 5108-2 acts as a back pressure or pressure sustaining valve. In this configuration, the valve maintains a constant upstream pressure regardless of fluctuating downstream demand. When used in a bypass line, the same model will function as a relief valve.
Features & Benefits
- Relief: Maintains a constant inlet pressure by relieving excess high pressure
- Sustaining: Prevents pressure from dropping below a minimum
- Inlet pressure is accurate over a wide range of flow
- Inlet pressure is adjustable with a complete range of control springs
- Quick opening with controlled closing
