CA-1/CA-2 Back Pressure / Relief Regulator
The Model CA-1 and CA-2 are compact back pressure regulators designed for controlling inlet pressure by relieving excess pressure. Both models are available with a forged Bronze body or stainless steel (SST) barstock body, making them suitable for various industrial applications. The Model CA-1 can control inlet pressures between atmospheric and 525 psig (36.2 Barg), while the Model CA-2 is designed for pressures up to 610 psig (42.0 Barg). These regulators feature self-aligning plug/seat mechanisms that provide tight shutoff capabilities, ensuring minimal leakage and reliable performance.

Advantages
- Self-Aligning Plug/Seat: The seat ring floats within a mechanically contained zone, ensuring proper alignment and tight shutoff.
- Tight Shutoff: Lapped seat surfaces allow for leakage rates to approach the levels of composition seats, providing reliable sealing and minimal leakage.
- Versatile Design: Suitable for various fluids and gases, including air, oil, water, and cryogenic gases, with the exception of steam service.
Industries
- Fuel Oil Systems: Used as a bypass flow regulator.
- Cryogenic Gas and Liquid Handling
- General Industrial Applications: Air, oil, water, and gas services.
- Sour Gas Service: Suitable for sour gas handling.
Applications
- Liquid Recirculation Around Pumps: Widely used in systems where maintaining consistent pressure is critical.
- Bypass Flow Regulation: Ideal for use in fuel oil systems and other applications where excess pressure needs to be relieved.
- Cryogenic Applications: Effective in both cryogenic gases and liquids, ensuring safe and efficient pressure control.
- General Services: Applicable for various industrial processes involving air, oil, water, and gas. Not recommended for steam service.
