A-T Controls valve systems tailored for ammonia, oxygen, chlorine, and beyond

Solutions for chemical processing are available from A-T

A-T Controls products are available through John Brooks Company Limited, including a wide selection of valves. Another option available is the manufacturer’s chemical services for chemical processing. An important industry with high safety standards, the chemical sector deals with various gases and liquids that require specific systems.

From ammonia to oxygen, A-T’s chemical services cover many substances that require valve systems with specific constructions to deal with their individual properties.

Severe irritation from exposure

Among the many types of substances with which A-T Controls systems work, with the assistance of John Brooks Company:

• Ammonia. A colourless gas with myriad uses, including as a refrigerant or a compound in producing fertilizers. Common states and compounds include liquid ammonia, anhydrous ammonia, and ammonium hydroxide. Intrinsically dangerous due to flammability; exposure can cause severe irritation. A stable ammonia system needs careful material selection.
• Butadiene. A colourless gas, sometimes condensed into fluid, used mainly as a monomer to create various kinds of polymers and copolymers, or as a chemical intermediate in the manufacture of industrial chemicals.
• Caustics. Compounds that corrode certain materials they contact. Common examples include sodium hydroxide and potassium hydroxide. Skin contact may cause severe burns, while inhalation could damage respiratory systems, so careful selection of materials and characteristics are crucial for valves.
• Chlorine. A highly reactive and toxic substance in all concentrations. Customers should consider whether a chlorine system is wet (more than 150 parts per million of water) or dry (less than 150 parts per million) when determining construction materials.
• Ethylene oxide. A flammable and explosive substance. Also a carcinogen that can also cause nerve damage. Useful in manufacturing detergent and cosmetics and for sterilizing surgical tools, but careful material selection is imperative.
• Hydrogen peroxide. A colourless fluid for disinfection and bleaching, but explosive and hazardous if handled incorrectly. Users should determine if the system has diluted or higher concentrations of this liquid and the application temperature.
• Oxygen. Necessary for life, but highly reactive at certain pressures and temperatures, with effects ranging from rust to explosion
