Three Piece Ball Valve

Salient Feature

  • The valves are designed to ensure that ball port fully aligns with body throat port in fully open position.
  • The blow out proof over size steam operated the valve safety even at high differential pressure a seal enabling replacement of gland packing even when valve may under pressure.
  • Bi- directional shut off
  • Ball is a heart of ball valves. Owing to the accurate manufacturing the ball is extremely spherical. Its mirror finish surface increase the sealing life and low operating torque.
  • High flow capacity with negligible pressure loss.
  • Unique flexible lip seats exert continues sealing pressure automatically compensate for wear and for changes in temperature & pressure, and provide extremely high cycle life.
  • Full port valve offers and resistance to flow operation is always easy, even when valves are operated infrequently.
  • The valve wrench (handle) is always parallel the flow passage of the valve.
  • Joints between bodies and body connectors in the case of flanged valve do not affect normal bolting or unbolting connection pipe works.
  • Body design provides adequate resistance against any permanent distortion under hydrostatic test and working condition.
  • Screwed end valves intended for assembly with pipe threads according to IS-554/BSP thread.
  • Flanged end valves are supplied undrilled unless other wise specified by the customer at the time of placing order with us along with standard in which drilling is desired
Option
  • Design available with mounting pad conforming to ISO for easy actuator adaptation.
  • Electro less nickel plating ball are also available on request.
  • Locking arrangement
  • Gear box, electric or pneumatic actuator design available
  • Single Piece, Two piece design available on request
  • We can offer valves under X-ray quality on request
