Capacity Range: The B177 model is ideal for systems with capacities ranging from 100 to 350 gpm (22.7 to 79.5 m³/hr), offering versatility for various flow rates.

Pressure Sensing Line: To operate effectively, the valve requires a pressure sensing line from the storage tank to ensure proper valve function and accurate pressure regulation.

Differential Back-Pressure Valve: The B177 valve can also function as a differential back-pressure valve, ensuring adequate pressure on flow meters to maintain accuracy and prevent underreporting of flow.

Size Availability: The valve is available in 2″ and 2-1/2″ sizes, making it adaptable to a variety of pipeline configurations and systems.

Protective Function: The B177 valve is designed to provide protection against overpressure situations, thereby safeguarding the integrity of positive displacement pumps and related equipment.
