FB5C Series Sanitary Back Pressure Regulator
3A and FDA approved, Self-draining, CIP/SIP, no guiding surfaces in the fluid
The FB5C Series is available with a hard seat and a variety of diaphragm and o-ring materials, making the valve well-suited for virtually any sterile back pressure application.
The FB5C operates by sensing the inlet pressure, or back pressure, beneath the diaphragm, as flow enters from inlet port on the side. As the back pressure exceeds the setpoint, the diaphragm force compresses the range spring permitting the stem to move from the seat toward the open position. As the flow increases, the back pressure is relieved and the spring and diaphragm relax, allowing the stem to return to the normally closed position. If a different set point is desired, a simple turn of the adjusting screw will increase or decrease the setting to any set point within the range covered by the regulator’s spring.
