Jordan valves for the chemical processing industry are engineered to provide precise pressure control, chemical resistance, and long-term reliability in environments handling corrosive, high-purity or hazardous fluids.

Key Features Chemical Pressure Regulating Valves

Chemical-Resistant Materials – Jordan Valve’s chemical process 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 chemical pressure regulating 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.
