NH3 (Anhydrous Ammonia) Needle Valves

Our NH3 (anhydrous ammonia) neelde valves (Catalog No. A-1000) are designed for use in ammonia tanks to provide a shut off for the pressure gauge. Its purpose is to allow the operator to remove the gauge for repair or replacement without evacuating the container. The A-1000 is also used on applicators to shut off the supply of NH3 to one or more knives.
