Chlorine Service

The Habonim "K" Series Chlorine Service ball valves are suitable for use with chlorine according to the guidelines of the Chlorine Institute Pamphlet 6 for "Piping Systems for Dry Chlorine". These valves are ideal where the demanding requirements for high quality, meticulousness material selection, cleaning and reliability are essential for the valve function.


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.

Dry Chlorine Systems

Valves for Dry Chlorine Systems are used with chlorine in dry or liquid state at temperatures between -101°C (-150°F) and +149°C (+300°F). In general, steel piping is recommended for handling dry chlorine, defined as containing no more than 150 PPM of water by weight. Carbon steel is not recommended for service below -29°C (-20°F). It ignites in chlorine near 251°C (483°F). Stainless steels Type 300 series have useful properties for service at low temperatures but can fail due to chloride stress cracking, particularly in presence of moisture at ambient and elevated temperatures. Monel and Hastelloy-C are the recommended material for ball and stem, with reinforced PTFE seats. Body seal and stem seal can be PTFE, or graphite for firesafe valves.

Recommended Materials of Construction

0-20 PPM Hastelloy-C ball and Monel stem
20-50 PPM Hastelloy-C ball and stem
0-50 PPM Hastelloy-C ball and stem (for end of line service)

The ball has a relief hole on it's upstream side, to insure that excess pressure in the ball and body cavity of closed valve will relieve spontaneously toward the direction of high pressure. The valve has a directional arrow, showing the flow direction. The valve has a blowout proof stem. Stem seals can be externally adjusted. Valves are available in firesafe construction. Habonim carries a wide selection of valves suitable to fulfill most applications. Flanged valves from 1/2" to 8" (class 150# and 300#), or three piece valves from 1/4" to 4". Valves are specially degreased, cleaned, assembled and packed in a cleanroom in accordance with "Habonim ball valves for Chlorine Service" specifications. Special chlorine service lubricants are used for valve seats and stem seals. Valves with desiccants (silica gels) are bagged and sealed in polyethylene bags, tagged with a sticker "For Chlorine Service". Valves for chlorine service are identified by a letter "K" before the series number. Valve sizes 1/4" to 2" are fitted with a yellow sleeve on the wrench.


Valves can be fitted with optional "Fugitive Emission Kits" which have a secondary stem packing to eliminate stem leakage and two monitoring ports for detection and accumulation of possible leaks. Locking devices are available, including the unique design for LLP (Locked in Last Position). Stem Extensions to provide insulation of pipe. Valves can be used with the Habonim Compact Actuator for automation and remote control.
