Key Features for Chemical Processing Applications

  • Chemical-Resistant Materials – Jordan Valve’s regulators and control valves are available in materials like stainless steel, Hastelloy, and Jorlon diaphragms, ensuring compatibility with aggressive chemicals, acids, solvents, and high-temperature steam.
  • Precise Pressure and Flow Control – Designed for applications requiring consistent downstream pressure, back-pressure regulation, and vacuum control, these valves help maintain stable process conditions in reactors, distillation columns, and storage tanks.
  • Globe-Style and Cage-Guided Valves – Providing high flow capacity and tight shutoff, these designs prevent leakage and ensure accurate regulation in critical chemical processes.
  • Sliding Gate Technology – Featured in many Jordan Valve regulators, this innovation offers low friction operation, reduced wear, and longer service life, making it ideal for handling corrosive or high-viscosity fluids.
  • Differential and Vacuum Regulators – Used in applications requiring precise pressure differentials, such as gas blanketing, chemical dosing, and vacuum distillation.
  • High-Purity Solutions – Certain models are designed for industries requiring ultra-clean operations, such as pharmaceutical and specialty chemical production.

Jordan Valve’s chemical process valves are trusted across industries like petrochemicals, industrial gas production, fine chemicals, and bulk chemical manufacturing, ensuring process stability, reduced downtime, and enhanced safety.

How Our Local Sales Representatives Can Help

  • Proper Valve Sizing – Selecting the right valve size is critical for achieving accurate pressure control and efficient flow management. Our experts can help calculate the correct valve size based on your process conditions, flow rates, and pressure differentials.
  • Material Selection for Chemical Compatibility – Given the wide range of corrosive, high-purity, and hazardous chemicals used in processing applications, our representatives can recommend the best valve body, trim, and diaphragm materials to ensure long-term durability and compliance with industry standards.
  • Application-Specific Solutions – Whether you need a back-pressure regulator for reactor pressure control, a pressure-reducing valve for steam heating, or a vacuum regulator for distillation processes, our team will help match the right product to your exact needs.
  • Custom and Specialty Configurations – If your application requires a unique valve configuration, our representatives work closely with Jordan Valve’s engineering team to provide customized solutions that meet your process demands.
  • On-Site Support and Troubleshooting – Many of our local sales representatives offer on-site evaluations, system audits, and technical troubleshooting to help optimize your valve performance and reduce maintenance costs.
