Cast Steel Flanged PN40 Parallel Slide Valves with Handwheel

Flanged Parallel Slide Valves

  • Parallel slide gate valves use system pressure and position to provide positive isolation instead of a wedge action.
  • The spring is fitted between disc to provide initial searing force, and do no maintain sealing force.
  • Once the disc is in position, in sot necessary any additional torque to achieve positive seal.
  • Parallel slide gate valves require smaller operative forces and therefore have a longer life.
  • The wiping action of the discs over seats meanwhile operating the valve removes debris and prevent premature wear of the components.
  • This debris protecting action avoid seat failures and leaking of valves and erosion.
  • Parallel slide gate valves provide a smooth flow path between seats.
  • Seal is established on outlet seat face only. Self-Aligning.
