Pressure Seal Globe Valve Working Principle:

Pressure Seal Globe Valve is engineered for accurate flow regulation and dependable shut-off in high-pressure and high-temperature piping systems. The threaded stem moves the disc linearly towards or away from the seat to control the flow of steam, oil, gas, and process fluids. Unlike conventional bolted bonnet valves, the pressure seal bonnet utilizes internal line pressure to enhance the seal between the bonnet and valve body, providing improved leak-tight performance as operating pressure increases. This self-energizing sealing design reduces bolting stress, minimizes maintenance requirements, and delivers reliable performance in critical services such as power generation, refineries, petrochemical plants, and industrial process systems. The valve is widely used where severe operating conditions demand exceptional pressure integrity and long service life.
