| Description: | The 441-S models are balanced valve, spring type regulators designed for use in low pressure, high capacity systems. They are general purpose regulators that are manufactured in a selection of pipe sizes and inner valve sizes. They are extensively used and have been proven in many types of distribution and industrial applications. Simple basic design has been combined with sturdy construction to make them exceptionally dependable with unique features which make them easy to adjust and service.
Model 441-57S, these high pressure, large capacity regulators incorporate a "roll-out" diaphragm that approximates the performance of a pilot operated regulator. The roll-out diaphragm makes this exceptional performance possible because its action reduces "droop" to a minimum. The 441-57S models also offer the advantages of simplicity, dependability, freedom from freeze-up, and exceptionally fast response. Model 441-X57, a unique high pressure, large capacity spring operated regulator that incorporates the same "roll-out" diaphragm principal that achieved such success in the widely used 441-57S regulator, but at higher outlet pressures. The 441-X57 offers pilot type performance with spring operated regulator simplicity. The roll-out diaphragm makes this exceptional performance possible, because its action reduces "droop" to a minimum. The 441-X57 also offers fast response and ease of installation, adjustment, and servicing. |
