Hydrogen Fluoride HF – Anhydrous

Process:
Anhydrous Hydrogen Fluoride or AHF is extremely hazardous in both liquid and vapor states. It can cause severe injury to any tissue with which it comes in to contact. Exposure by contact with skin, or by inhalation or ingestion, can lead to severe toxic systemic effects and potentially death. Eye contact from vapor or liquid can result in blindness if not treated immediately and death can occur from severe electrolytic imbalance. Therefore, ensuring that AHF is not allowed to escape from the valve is of critical importance for plant safety.
Solution:
HMV’s 8850 series of pneumatically actuated bellows sealed globe isolation valves are designed and manufactured in accordance to and approved by Euro Chlor to their latest standard, ensuring that hazardous chemicals such as AHF cannot escape from the valve by way of an external leakage. The correct choice of valve size, compatible materials, radiography of castings, two designs of seals around the stem and thorough testing within our factory before delivery, ensures safe operation for the end users.
Benefits:
The valve has been used continuously throughout years of operation without any external leakage to the environment and keeping the plant operators safe from the toxicity associated with AHF. The end user has praised the design, manufacturing specifications, standards, and on-site application of our 8850 series valves. They continue to use HMV valves across their site and we look forward to working with them to continue to reduce their operating and maintenance cost when working with hazardous chemicals.
