Most TIH (Toxic Inhalation Hazard) gases are stored as liquid by pressurized and/or decrease temperature, e.g. Chlorine, Hydrogen-Fluoride, Ammonia, Sulfer-Dioxide etc.

Those TIH gases has characteristics of severe corrosive, super-reactive to water, sometimes polymerization or self-combustion when expose to oxygen in the air.

Thus, leakage or emission become very dangerous and lethal.

This video shows that liquid chlorine can be 457 times expansion when release to atomosphere.

High quality severe service valves then are crucial components for all related chemical-gases process as safety is NON-NEGOTIABLE.

DESCOTE valves production and business core value can be described in 4P philosophy including;

1. Protect Human Lives
2. Protect Assets and Interests
3. Protect Industry
4. Protect Environment

Other than chlorine related, Fluorine or Hydrogen-Fluoride is also important process, especially in petro-chemical industry.

DESCOTE valves have been proven and qualified in global market, with prestige brand of DESCOTE has been indicated in Manufacturers Standardization Society (MSS) ,​ Service Practice 160 (SP-160), “Valves for Hydrogen-Fluoride Alkylation Service” (reference : www.msshq.org)
