Standard Features:

• KELITE ultra-low temperature ball valves are used in pipelines, pumping and compression stations, offshore, onshore, subsea and cryogenic applications.
• The extensive size range and pressure class are available in a variety of materials including Alloy & Stainless steel suitable for general to severe service conditions.
• The KELITE ultra-low temperature 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 ultra-low temperature 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 KELITEultra-low temperature 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.
