Construction

Diaphragm valves don’t have gland seals. The external sealing is assured by thin metal discs (diaphragms), which hermetically divide the spindle chamber from the fluid flow area.
The main parts of the valves are made with the following materials

  • Hot forged brass body as per BS-218

  • Extruded brass for the spindle

  • Special spring steel for the spring

  • Engineering Plastics for seat sealing gaskets
Application These diaphragm type hand shut off valves are designed for installations in liquid, suction and hotgas lines of commercial refrigerating systems and on civil and industrial air-conditioning systems.
