Barstock Construction, Low to Medium Flow, Very Low Pressure

The JSRULP is a pressure regulating valve ideal for low flow, very low pressure precision regulation of clean compressed air and gas used in pharmaceutical and bio-pharmaceutical R & D, Pilot and Production facilities.

It is designed specifically for use on traditional stainless steel and single use disposable applications including:

  • Small sterile vessels
    - Gas overlay (blanketing)
    - SUD bag integrity testing/inflation - Incubators
  • Time/pres filling machine product hold vessels


Features & Benefits
  • No exposed threaded connections below diaphragm
  • In-line removable seat and trim facilitate cleaning and routine maintenance
  • Barstock construction guarantees material integrity and surface finish
  • Very low lockup with EPDM seat material
  • High rangeability and relatively low set point offset lessens the need for reduced trim sizes
  • Minimized internal volume
  • Proprietary Jorlon diaphragm material provides exceptionally long life
  • Soft seat material for ANSI Class VI shutoff
  • Size: 1/2″ & 3/4″ (DN15 & DN20)
  • Soft Seat Materials for ANSI Class VI Shut-off: EPDM to +300°F (150°C) FDA, USP Class VI
  • Body Material and Trim: ASME SA479 316L (UNS 31603) is standard. EN 10272:2000GR 1.4435, AL-6XN, Hastelloy C-22 and others are optional
  • Max. Inlet Pressure: 150 psig (10,5 bar)
  • Max. Outlet Pressure: 25 psig (1,7 bar)
  • Spring Ranges: -18″ wc 90.11 – 0.65 psi (7,47 – 44,79 mbar); consult factory for other spring ranges
  • Flow Charactertistics:
    – High Flow: Trim Cv 0.8; Cv for relief valve sizing is 1.9
    – Low Flow: Trim Cv 0.5; Cv for relief valve sizing is 0.6
  • Diaphragm: Thin Jorlon FDA, USP Class VI
