CAC-IBR – Bộ điều chỉnh áp suất ngược

The IBR model in Welker’s I-Series Instrument Regulators is a standalone, spring-loaded, piston-sensing back-pressure regulator suitable for controlling gases and low-viscosity liquid products. By controlling its inlet pressure, the IBR helps to balance system pressure and product flow.

• Materials of Construction:
  • Body: 316/316L Stainless Steel
  • Seat & Seals: Viton®
• Maximum Allowable Inlet Pressure: 3600 psig @ -20 °F to 200 °F (248 barg @ -28 °C to 93 °C
• Ports:
  • Inlet: ½” FNPT
  • Outlet: ½” FNPT
• Flow Coefficient (CV): 0.03, 0.06, 0.10, 0.40
• Pressure Control Range: 25 up to 2250 psig (1.7 up to 155 barg)
• Weight: 8 lb (3,6 kg)

CAC-ISPE – Compressed air flow regulator

The ISPE model in Welker’s I-Series Instrument Regulators is a cost-effective, standalone piston-sensing instrument regulator suitable for regulating air and light gases, such as hydrogen.

With global and industrial decarbonization goals, the development and deployment of hydrogen and fuel cell technologies are growing in importance. Welker’s ISPE Instrument Regulator can be used across the hydrogen value chain to reduce the pressure of the hydrogen gas to a lower outlet pressure safe for the downstream equipment in your application, helping prevent costly damage and interruptions to operation.

• Temperature Range*: 32 °F to 392 °F (0 °C to 200 °C)
• Ports: ¼” FNPT or SAE Inlet, Outlet, Relief, and Gauge
• Flow Coefficient: 0.02, 0.06, 0.10
• Weight: 0.5 lb (0.2 kg)
• Pressure Control Ranges:
  • 0–25 psig (0–1.7 barg),
  • 0–50 psig (0–3.4 barg),
  • 0–100 psig (0–6.8 barg),
  • 0–200 psig (0–13.7 barg)

CAC-FIR-1 – Filter / Instrument Regulator

The Welker Regulators FIR-1 Filter / Instrument is designed to filter and provide regulation of an instrument pneumatic supply. It is intended for use as part of instrument packages.

The regulator of the FIR-1 is non-relieving. Welker recommends that a relief valve, such as the Welker RV-1 or RV-3 series relief valves, be installed downstream of the FIR-1.

• Materials of Construction: 316 / 316L Stainless Steel, PTFE, Teflon® or Kel-F® Seat, Viton® Others Available
• Filter Element: 10 micron or 35 micron Linear Polyethylene
• Operating Temperature: 200°F (94°C)
• Inlet Pressure: 0-3000 psig (0-207 Barg)
• Instrument Air Connections: 1/4″NPT
