Lever Valves

Two/three lever valves are used for the isolation of fluid flow. These valves are ideal for unidirectional shut-off. Lever valves can be mounted with counterweights for emergency shut-off in gas pipelines.
TECHNICAL DESCRIPTION:
The valve mainly consists of a body, disc, levers, linkages, stuffing boxes, and a drive mechanism. The drive mechanism is coupled with the shaft of the valve and movement of the shaft results in the valve opening /closing operation. Specially designed levers and linkages guide the movement of the disc in such a way that the disc moves parallel to the seat for some distance and then starts to rotate until the valve is completely open. This movement ensures no rubbing of the seal and seat which enhances the life of the seal.

SPECIAL FEATURES
  • Self-lubricating inner bushes which eliminate the need for external lubrication.
  • The valve has a safety feature of closing automatically in case of emergencies like a power failure.The valve has a safety feature of closing automatically in case of emergencies like a power failure.
  • The seating surfaces are ground and lapped to achieve a high degree of sealing in case of metal- to-metal sealing
  • Steam purging arrangement for melting tar and drain ports for removal of molten tar and other trapped material.
  • Manual override option available
