The Ammonia Globe Valve is a globe valve specifically designed and manufactured for ammonia gas or liquid ammonia media systems. Due to the corrosive and hazardous nature of ammonia, the selection of valves requires extremely strict criteria, including material corrosion resistance, excellent sealing performance, and structural design. This valve achieves precise control and tight shut-off of ammonia flow through the linear movement of its disc along the fluid's centerline. Ammonia globe valves are crucial components in refrigeration, fertilizer production, chemical, and industrial gas applications, regulating and shutting off ammonia flow to ensure system safety and efficiency.
