CAST IRON DOUBLE FLANGED SLUICE VALVE

Sluice Valves are designed by nominal Pressure (PN) defined as the maximum permissible guage working pressure (i.e. Mpa) as follows :

Nominal Pressure (PN)

Nominal Size

MPa

mm

PN - 1.0

50 to 1200

PN - 1.6

50 to 600

All flanged are faced and drilled as per IS-1538/1993. However as special cases flanges may be drilled as per BS, DIN, ANSI and other international Standards upon request to suit specific requirements.

Valves generally come with Cap or Hand wheel at the top for operation. However Valves with Spur gear, Bevel gear, Worm gear, Head stock arrangements, Chain Wheel arrangements, Bye Pass arrangements may also be supplied against specific requirements.
