Silent Features :
- 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 otherwise specified by the customer at the time of placing order with us along with standard in which drilling is desired
