DESIGN
Pressure seal valves are intended for high-pressure and high-temperature applications in all types of fluid, except where severe coking may occur.
A selection of designs and materials would give an excellent service in nuclear steam generating stations, industrial/chemical plants, and thermal power plants.
The pressure seal valve provides the most efficient use for flow passage and sealing, and results in significant weight saving and ease and simple installation and maintenance. Manufacturing and quality assurance procedures include extra controls of dimensional and non-destructive examinations and tests on critical areas such as gasket sealing, weld ends, or stelite sealing surfaces.
CONSTRUCTION
When designing a PK valve, casting of body and bonnet shall be considered thoroughly as a quality requirement.
