Type 41-1- T41-1 Adjustable Precision Regulator
The Bellofram Precision Controls Type 41-1 is an adjustable precision pressure regulator designed for high-flow, low-droop industrial pneumatic control. A Bellofram rolling diaphragm improves sensitivity, while a soft-seat valve stem and aspirator help maintain stable downstream pressure as flow conditions change. The Type 41-1 supports maximum supply pressure up to 250 psig, uses 1/4-inch NPT ports, and provides compact pipe, panel, or bracket mounting without the bonnet vent port used on the Type 41-2. Applications include instrumentation, medical equipment, inert gases, pulp and paper systems, industrial tools, and QC operations.
Features:
- Superior regulation characteristics
