High Performance, Point-of-Use Regulators - SQ Series
Brand: Parker HannifinThe SQ Series of regulators are high flow, high performance point-of-use regulators designed to be used in process gas cabinets for gas companies, equipment manufacturers and end users.
The SQ Series of regulators provide precise control of the process gas pressure at or near the tool.
The results are stable flow and pressure to the mass flow controller.
The SQ60SA provides precise pressure control for point-of-use in the sub-atmospheric range.
Features- Metal-to-metal, diagram to-body seal
- Standard full internal electropolish
- Design and materials of construction ensure compatibility with the high flow of corrosive gases
- Sub-atmospheric available (SQ60SA)
