37T-4 Description Generant CRM Series pressure regulators provide high flow and quick, positive shut off at the desired set pressure. The regulator design is a non- balanced, spring reference, pressure reducing type regulator. They were designed especially for use as pressure build regulators for cryogenic liquid cylinders but can be used in many other applications. Solid, non-tied diaphragm provides leak-free and long-lasting performance. Optimized diaphragm and adjustment spring designs provide high flow performance. All CRM Series regulators are supplied factory pre-set and cleaned for oxygen service. Features • OPTIMIZED FOR HIGH FLOW: Optimized Spring and Diaphragm Design allows for high flow rates and low pressure drop. • QUICK SHUT-OFF: Regulators transition from the flowing condition to shut in a tight pressure band. • SOLID, NON-TIED, DIAPHRAGM: Solid diaphragm eliminates potential leak path and increases sensitivity. • DESIGNED FOR CRYOGENICS: All materials were selected specifically for use in cryogenic environments. • CLEANED FOR OXYGEN SERVICE: Regulators are cleaned for use in Oxygen service standard.
