The family of 461-S low-pressure regulators is balanced-valve, spring-type regulators for distribution and industrial applications. Because of their simple design, sturdy construction, and fast response, they are exceptionally dependable. Contoured body passages reduce turbulence in gas flow. Operation is sensitive and stable, and servicing and adjusting are easy.

These models are ideal whenever a single-seat regulator is too small and 2" balanced-valve regulators are too large. The large exit areas of the 461-S give them a broad range of capacity. This makes them suitable for a wide variety of load handling requirements.

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.
