Key Features
  • Integrally molded seat liner on the body, which ensures excellent dimensional stability & guaranteed seat tightness.
  • Seat liner extending onto the contact faces ensures perfect sealing and eliminates the need for separate flange gaskets.
  • A unique triple sealing system for shaft sealing ensures zero leakage of the media past the shaft seals.
  • A narrow land disc ensures perfect sealing with the least operating torque requirements.
  • A fully universal body design ensures fitment of the valve between companion flanges of all popular standards (viz: ANSI, BS, DIN, JIS, IS, etc. ).
  • A ten-position notch disc and hand lever ensure locking of the valve in 8 intermediate positions in addition to the closed and open positions. Hand lever lockable through padlock for tamper-proof positioning.
  • Body castings are made of superior FG 260 grade cast iron to ensure additional strength.
  • Valve disc made of ductile cast iron instead of cast iron to withstand against possible water hammer or pressure surges.
  • A truly line-size body bore to ensure maximum flow capacity with the lowest pressure drop.
  • Shafts are made of martensitic stainless steel to ensure maximum strength and torsional rigidity.
  • Both top and bottom shaft swiveling are guided by self-lubricated PTFE bearings.
  • Fool-proof hand lever designed to prevent the accidental pinching of hand between the handle and locking lever.
