- KELITE Side Entry ball valves are used in pipelines, pumping and
compression stations, offshore, onshore, subsea and cryogenic as
well as abrasive and high temp applications.
- The extensive size range and pressure class are available in a
variety of materials including Carbon, Alloy & Stainless steel
suitable for general to severe service conditions.
- The KELITE trunnion mounted ball valves are available with Double
Block & Bleed independent of the seat type.
- Single piston effect (SPE) is the standard feature for the seat
rings of the KELITE trunnion mounted ball valves.
On a SPE seat ring: The pressure acting on the upstream side of the
seat ring generates a force which push the seat towards the
ball.The pressure acting on the downstream side of the seat ring
generates a force which pull the seat ring away from the ball.
Any overpressure which may be generated by the thermal expansion of
the fluid trapped in the body cavity with the ball in fully closed
position, will be automatically discharged in the line on the lower
pressure side. - Double piston effect (DPE) is a standard feature for the seat rings
of the KELITE trunnion mounted ball valves & recommended for welded
body valves. On a DPE seat ring, both the pressure acting on the
upstream side of the seat ring and the pressure acting on the down
stream side of the seat ring, generate a force which push the seat
towards the ball. With this type of seat ring, the eventual
overpressure which may be generated by the thermal expansion of the
fluid trapped in the body cavity with the ball in fully closed
position, can be discharged by the use of an external safety relief
device. The Double Piston Effect grants a double sealing feature,
if the upstream seat ring is damaged, the down stream seat grant
the sealing feature of the valve.
