Gate Station Regulators – Model 441s & Model 461s
Model 441-S
Large-capacity, low-pressure regulators delivering fast response, high sensitivity, and stable control; commonly used for monitoring without modifications
Model 461-S
Intermediate-capacity balanced-valve regulators with stable control and broad capacity range
Model 441 and Model 461
These large-capacity regulators deliver precise pressure control while maintaining a high level of sensitivity and stability. The combination of their fast response, dependability and accuracy make these models ideal for monitoring, as well as other applications that need speed and accuracy. They’re ideal for large-capacity applications including district regulator stations, city gate stations, and industrial applications.
A unique feature of our Model 441 and Model 461 regulators is the roll-out diaphragm. The roll-out diaphragm is used on the 57S and X57 models, and the action of this diaphragm is so effective that “droop” is practically eliminated.
Features & Benefits
Different diaphragm cases, bodies, and valve sizes provide a wide array of capacities.
Simplified maintenance and lower maintenance costs than pilot-operated regulators.
Roll-out diaphragm on 57S/X57 models offers near pilot-operated performance with faster response.
Direct-acting regulators reduce the risk of freezing by utilizing larger orifices than pilot-operated regulators.
They often can stay in service for decades.
The fast rate of response makes these regulators ideal for use as a monitor regulator.
