The 432 Series dual stage regulators regulators are intended for primary pressure control of ultra-high purity, corrosive, or toxic gases. Two stages of pressure regulation minimize pressure variation regardless of supply pressure variations making this regulator ideal for applications requiring constant pressure control and delivery.
Typical Applications
- EPA Protocol Gases
- Gas and Liquid Chromatography
- High Purity Carrier Gases
- Zero, Span, and Calibration Gases
- Ultra High Purity Chamber Pressurization
- Corrosive Gases
Features
- CAPSULE® Seat Design features integral 360° filtration in both stages 316L
- Stainless Steel Diaphragm prohibits inboard diffusion
- Cleanroom Assembly eliminates contamination at installation
- Front and Rear Panel-Mountable facilitates a variety of system configurations
- Pipe Away Relief Valve vents exhaust gas safely
- Metal-to-Metal Diaphragm Seal prevents gas contamination
- 10-Micron Filtration in Both Stages provides fail-safe seat performance
