The PR3G is a hard seated pressure reducing and regulating valve suitable for steam applications with supply pressures up to 300 psig (20,7 bar). The PR3G offers exceptional performance, easy
in-line maintenance, and heavy duty construction for reliable, long-term operation.
Steriflow FB5C Series Sanitary Back Pressure Regulator
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.
The FB6C Series sanitary pressure regulator is designed to regulate pressure in systems requiring the maintenance of sanitary conditions. The FB6C operates by sensing pressure under the diaphragm on the downstream side of the seat. As the downstream pressure approaches the setpoint, the force caused by the pressure acting on the diaphragm overcomes the force of the range spring, and the plug begins to move toward closed. This reduces the downstream pressure and maintains the set point. If the pressure underneath the diaphragm begins to fall, the spring forces the plug to move down towards open, to allow the setpoint to be maintained.
Steriflow FBCPM Series Sanitary Air Loaded Pressure and Back Pressure Regulators
The FB5CPM (inlet) and FB6CPM (outlet) are air loaded sanitary constant pressure modulating valves, designed to allow the user to change set-points remotely via a cabinet or panel mounted air regulator, or through a distributed control system or PLC, using an I-P transducer. The CPM valve is an ideal choice for automating and maintaining constant pressure set points on the inlet side of the valve for control operations, whether they are process set points or points to fully open the valve for rinse, CIP or SIP. The valve is preferred in HTST/UHT Pasteurization, after Heat Exchangers, Separator equipment, bottling lines, etc.
