Pressure Seal Check Valves are ideal for high pressure steam, liquid, catalytic reformers, hydrocrackers and other demanding services. Check valves are normally designed for horizontal flow condition, but can also be installed in the vertical pipeline, but in the vertical pipeline the flow must be upstream and below the disc.
The basic concept of Pressure Seal Check Valves is that the first cap pull bolts tighten the cap, which seals the pressure sealing gasket to the body. The system pressure then provides more force to close the seal. Thus, the potential for leakage from the body / bonnet hinge decreases as system pressure increases.
High pressure, In the challenging world of high temperature valve applications, Pressure Seal Globe Valve continues to offer a wide range of industries with a safe, leak-free, pressure-containing boundary. These valves are the most suitable method for narrowing at high pressure and temperature.
