Leader Forged Brass Gate Valve 2 MPa (IS 026)

The Leader Forged Brass Gate Valve (2 MPa) provides bi-directional flow isolation in compact industrial and residential piping systems. Manufactured according to IS 13114 standards, this heavy-duty, full-bore gate valve features a non-rising stem setup and deep-cut internal threads for maximum durability under pressure.

Key Product Features

  • Full-Bore Flow Design: Features an unobstructed, full-bore internal pathway that minimizes pressure loss across the line.
  • Pressure Re-packing System: Engineered with a back-seating facility that allows safe gland re-packing while the system is fully pressurized.
  • High-Tensile Brass Stem: Constructed with robust forged brass stems to resist torque shearing during manual actuation.
  • Clear Position Identification: Includes visual open/close position markings on the handwheel nameplate for easy operation.
  • Standard Parallel Threading: Screwed female parallel pipe threads designed in accordance with IS 554 specifications.
  • Screwed-In Bonnet: Built with an inside screw, non-rising stem, and integral seating surfaces for compact vertical footprint clearance.
