Chlorine Service

Chlorine is a hazardous and toxic material. It is a greenish-yellow, nonflammable gas with a distinctive, pungent odor. The gas acts as a severe irritant if inhaled. Chlorine is nonflammable in both gaseous and liquid states. However, it is capable of supporting combustion of certain substances. Chlorine is mainly used in manufacturing chemicals. These include solvents, pesticides and herbicides, plastics and fibers, refrigerants and propellants. It is also an ingredient in bleach, deodorizer and disinfectant. In addition, chlorine is widely used in bleaching pulp, paper and textiles; for drinking water and swimming pool purification; in sanitation of industrial and sewage wastes.

Vacuum Service

Standard Habonim Ball Valves, with no special preparation can effectively be used in limited vacuum service.  When Higher Vacuum Service is required, valves specially prepared, can be used down to 10-6 mm of mercury.

Cryogenic Service
 
All the cryogenic valves have an extended bonnet with an ISO 5211 mounting pad. The extension prevents cryogenic liquids from reaching the stem packing by enabling the liquids to boil and convert to gas. The balls have a pressure relief hole on the upstream side to prevent overpressure of the body cavity from thermal expansion. The valve is uni-directional with an arrow showing flow direction.
Oxygen Service

The normal oxygen content of air is approximately 21% by volume. Human exposure to atmospheres containing 12% or less oxygen will bring about unconsciousness without warning. Oxygen is an odorless, colorless gas, which has many uses in industry, especially in steel and chemical manufacture. It is nonflammable but, all materials that are flammable in air, burn much more vigorously in oxygen. Oxygen is shipped as a nonliquefied gas at pressures of 2000 psig (138 bar) or above, also as a cryogenic liquid at pressures and temperatures below 200 psig (13.8 bar) and -232 0F (-146.5 0C). Oxygen is produced at air separation plants by liquefaction of atmospheric air and separation of the oxygen by fractionation. Very small quantities are produced by the electrolysis of water.
