USG Model 441-S Regulator

When large loads are required, the Model 441-S has the larger bodies and valves for the job. Large, flexible diaphragms combined with precisely calibrated springs enable these large-capacity regulators to deliver precise pressure control while maintaining a high level of sensitivity and stability. The combination of their fast response, dependability and accuracy also makes the 441-S models ideal for monitoring, as well as other applications that need speed and accuracy.

When used as monitors, these low-pressure regulators assume control quickly if a failure in the operating regulator allows the outlet pressure to rise above its set point. With a fast rate of response, a regulator is crucial in the event of an emergency. No modifications are required for use as a monitor, even if used as a monitor for other types of regulators.

Benefits

• Monitors set point pressure
• Responds quickly to excessive pressures
