Cashco - Model 1000HP -Process Pressure Reducing Regulator

SHARE

The Model 1000HP is a high capacity, high pressure regulator used to control downstream pressure between 10 and 300 psig (0.69 and 20.7 Barg). Available in sizes from 1/2" through 2" (DN15 through DN50). The unique internal design allows use in a multitude of applications, including process fluids that normal pressure reducing regulators can not match. The most versatile self-contained, pressure reducing regulator available to users.

  • Streamlined Flow Path:Straight-through flow path reduces internal turbulence and resistance to flow, increasing stability and capacity.
  • High Inlet Pressures: Standard construction allows inlet pressures up to 740 psig (51.0 Barg).
  • High Outlet Pressures: Controlled outlet pressure up to 300 psig (20.7 Barg).
  • High Pressure Drop: Standard construction with extended guiding allows pressure drop up to 650 psid (44.8 Bard). This regulator is routinely applied in severe service conditions.
  • Flow-to-Open Plug: Provides unmatched rangeability – far greater than competitive flow-to-close designs. Highly stable at either high or low flow rates.
  • Versatility: Four body materials and nineteen trim material selections allow usage in a multitude of various fluids. Optional constructions extend the capability.
  • Protected Diaphragm Zone: Internal arrangement isolates the diaphragm from direct impingement, negating any flow induced instability at either low or high flow rates. Allows incorporation of dynamic boost from jet section. Uniformly registers pressure on the diaphragm.
  • Diaphragm Travel Stops: Incorporates mechanical stop in spring chamber to limit diaphragm uptravel and in body for downtravel, minimizing potential internal damage from over-travel conditions.
  • Service: Gases, Liquids, Steam
  • Line Size: 1/2" (DN15), 3/4" (DN20), 1" (DN25), 1.25" (DN32), 1.5" (DN40), 2" (DN50)
  • End Connections: FNPT, Extended Nipples, Flanged, BSPT Taper Threaded
  • Body Material: Carbon Steel, Stainless Steel, Ductile Iron, Bronze
