BS (H) 2 Series Regulator

Brand: Swagelok Company
The BS series back-pressure regulators are suitable for most gases and liquids.

The BS series regulators feature a choice of sensing types (diaphragm or piston), and seat and seal materials to accommodate a variety of pressure, temperature, and flow conditions.

The BSH series regulators are high-pressure versions of the BS series regulators, and the LBS series are low-pressure, high-accuracy versions of the BS series regulators.
Features
  • Piston sensing
  • Bottom mounting
  • Low-friction piston for better control
  • Maximum Inlet Pressure:
    • BS - psig: 5,800 (bar: 400, kPa: 39,990)
    • BSH - psig: 10,150 (bar: 700, kPa: 69,980)
  • Maximum Inlet Control Pressure:
    • BS - psig: 5,075 (bar: 350, kPa: 34,990)
    • BSH - psig: 10,150 (bar: 700, kPa: 69,980)
  • Sensing Type: Piston
  • Temperature Range: -20° to 80°C (-4° to 176°F)
  • Flow Coefficient: 0.10 Cv
  • Connections:
    • Intet/Outlet: 1/4" NPT
    • Gauge: 1/4" NPT
    • Vent: 1/8" NPT
  • Materials of Construction:
    • Body: 316L Stainless Steel
    • O-Ring: Fluorocarbon FKM, Nitrile, EPDM, FFKM
    • Seat: PCTFE, PEEK
    • Poppet: 431 Stainless Steel
    • Piston: 316L Stainless Steel
