DESIGN

Pressure seal valve are intended for high pressure and high temperature appilications in all types of fluid, except where severe coking may occur.
A selection of design and material would give an excellent service in nuclear steam generating stations, industrial/chemical plants and thermal power plants.
The pressure seal valve provide the most efficient use for folw passage and sealing, and result 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 stellite sealing surfaces.

CONSTRUCTION

- BODY AND BONNET
- BODY : Flow areas are designed for minimum turbulence and pressure drop.
- BONNET : Ample stuffing box and stellite back seat are to guide accurately stem and back seat.
When designing a PK valve, casting of body and bonnet shall be considered thoroughly as a quality requirement.

- BONNET TYPE
