JQF Valve manufactures the ammonia globe valve in stock, a type of valve used to control the on/off switching and flow rate of ammonia media. Typically made of cast steel, it features stable sealing performance and a long service life, meeting the needs of various operating conditions. Its operation involves turning a hand-wheel, which moves the valve stem up and down, thus controlling the opening and closing of the valve to regulate flow. The J41B PN40 ammonia globe valve is a manual, flanged, straight-through type valve with a nylon plastic seat sealing surface, a nominal pressure of PN40, and a carbon steel gate valve body. Applicable media include liquids, gases, ammonia, nitrogen, and hydrogen.
