Pressure Seal Globe Valves
Product Description The Pressure Seal Globe Valves is only suitable for full opening and full closing, and no adjustment and throttling are allowed. The globe valve is a forced seal valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface not to leak....
The pressure self-sealing globe valve is mainly suitable for cutting off or connecting pipeline medium in various systems of thermal power plants. Applicable medium: water, steam and other non corrosive media. Compared with other valve products, the valve features high temperature and pressure, unique self-sealing design, the higher the pressure, the more reliable the seal. Because of the special characteristics of performance and technology and working conditions, the products have formed the characteristics that can not be replaced by other products.
