What Are Aggressive Media Valves?

Aggressive media valves are inert solenoid valves that handle corrosive or abrasive liquids and gases. They must be compatible to withstand the harsh nature of different media repeatedly for long periods, while functioning efficiently and operating safely in hostile environments.

Key Features of Aggressive Media Valves

Material strength and resistance to failure are what set aggressive media valves apart from other solenoid valve designs. Other important features include a wide temperature range and long cycle life.

Wide Temperature Range

Extremely high or low temperatures may increase media volatility and affect the integrity of valve materials. Aggressive media valves are crafted to tolerate ambient and media temperature fluctuations.

That allows the valves to maintain consistent functionality, prevent leaks and isolate operators and users from hazardous exposure.

Extreme temperature changes can also wear on valve seals and gaskets. Aggressive media valve components are made of stainless steel, corrosive-resistant alloys and special plastics that cope with heat and cold.

Long Life Cycle

This valve’s resistance to deterioration supports efficient operation for long periods. Some can handle upward of five million cycles without integrity degradation or performance issues.

Manufacturers can help with the selection of proper valve body and elastomer materials for your application to extend cycle life.

High Chemical Resistance

The corrosive, reactive and chemically aggressive nature of some media degrades valve materials if they aren’t constructed to resist them. Stainless steel, certain alloys and inert plastics can handle aggressive media and difficult operating environments. Some inert solenoid valves come with corrosion-resistant linings and coatings that enhance durability.

Aggressive media valves have specially designed seals and gaskets that tolerate the impact of abrasive materials while maintaining a tight seal to prevent leaks.

Benefits of Using Aggressive Media Valves

  • Top-rated chemical resistance for application diversity
  • Flexible poppet diaphragm designed to isolate valve components from aggressive media
  • Configurations for inline/direct piping and manifold/subbase mounting
  • Designed to withstand fluid temperatures from 32⁰ to 203⁰ Fahrenheit and ambient temperatures from 32⁰ to 122⁰ Fahrenheit
  • Compliance with strict industry-specific operation standards
  • Resistant to deterioration, corrosion and abrasion
  • Long-term cost savings

Which Materials Can Aggressive Media Valves Control?

Liquids: Aggressive media valves tolerate corrosive liquids such as acetic acid, concentrated nitric acid, sodium hydroxide, potassium hydroxide, concentrated ethanol and acetone. They also regulate abrasive liquids that contain particles found in chemical applications.

Gases: This type of inert solenoid valve can handle corrosive gases such as chlorine and sulfur dioxide and acidic vapors like hydrogen fluoride and hydrogen bromide.

Air & Water: These valves are constructed to manage extreme temperatures that can generate stream. They function efficiently in humidity and chemically contaminated air that could cause corrosion in other models.
