Valves are available in a remarkable array of sizes and types, their variety driven by a combination of diverse application requirements and manufacturers willing to fulfill those requirements. One application subset, of which some knowledge is useful, is the requirement for accurate and reliable control involving very low flow rates.
The Low Flow Division of Jordan Valve specializes in control valves and pressure regulators for processes where very low flow rates are a requirement. The company's products cross the boundaries of many industry sectors, with variants applicable to many uses.
- Back Pressure
- Chemical Injection or Metering
- Flow Control
- Corrosive Media
- Cryogenic
- High Pressure
- High Temperature
- Mixing or Diverting
- Natural and Industrial Gas
- Offshore
- Pilot Plant
- Pressure Reducing
- Steam
- Research
- Zero Fugitive Emission
A number of installation and operation considerations may apply to these specialized valves that are different or more stringent than for larger flow rated valves.
- Clearance within the trim may be very small, to provide precise control of low flow rates. Valves should generally be applied to clean fluids.
- When installed, all piping should be properly cleaned, flushed, or blown out to remove all foreign matter.
- A line strainer of particularly fine mesh, in accordance with installation instructions for the particular valve in use, may be required for protection and to maintain proper operation.
- Other instructions that may apply specifically to an application or a valve product should be followed to assure best performance and longevity
