Product - E..S Spraywater Control Valve
Designed as a Z-body type valve, the E..-S’s anti-cavitation trim design forces the flow of spraywater through a three (optional four) stage cascade and an additional outlet cage.  The multistage seat is a capsuled design, keeping the flow of spraywater away from the valve body. This successfully eliminates damage to the valve body caused by erosion and ensures a faultless operation over many years of operation.​

​​Key features

  • Compact, robust design
  • Clamped trim for easy maintenance
  • Multi-step anti-cavitation trim
  • Bottom access body design
  • High rangeability

​​​K

  • Designed for conditions up to 320 bar at 340ºC
  • Tight shut-off (EN12266-1 Class B, MSS-SP61 or ANSI/FCI 70.2 Cl. V)
  • ​Wide installed base

​​Benefits

  • Top and bottom-guided valve stem design
    • Ensures excellent control of the medium throughout the range
    • Prevents the valve and piping from damage caused by stem vibrations
  • Bottom access valve body
    • Reduces maintenance costs to a minimum
    • All internal parts accessible without removing actuator
  • Multistage seat
    • Capsuled design to keep medium flow away from body
    • Eliminates damage caused by erosion​​


​​Typical materials


​​Applications

Normally used in spraywater applications where the pressure drop across the valve i​s rated as continuously high, such as:
  • High pressure bypass systems
  • Superheater spraywater injection systems
  • Reheater spraywater injection systems
  • Other spraywater systems requiring control valves for accurate spraywater control under rugged operation
