Steriflow FBCV Sanitary Control Valves - OR Version
The Steriflow FBCV O-Ring Series by Steriflow meets the rigid specifications for sanitary process control valves for customers who prefer an O-ring style stem seal. This valve series is suitable for various cosmetic, dairy, and food and beverage industries. Conforming to 3A guidelines, the FBCV is ideal for a wide range of flowing media in both the utility and process areas of sanitary systems.
In general, o-ring stem seals (what ASME BPE defines as sliding stem seals) for control valves on clean air and gas and liquid clean utility applications like USP Purified water and some CIP fluids. In contrast, diaphragm type control valves are on WFI (Water for Injection) systems for end of loop back pressure control, buffer dilution skids, and filtration skids for pressure and flow control and chromatography elution flow control.
The FBCV-OR's high rangeability, characterized trim, high capacities, superior temperature, and pressure ratings, and a selection of sealing methods make the sanitary control valve ideal for liquid, gas, and steam services. Whether the need is to control pressure, temperature, flow, pH, or another variable, the FBCV is the correct valve for your process.

The SIEMENS SIPART PS100 Electro-pneumatic Positioner
/p>
The SIEMENS SIPART PS100 electro-pneumatic positioners control the valve or damper position of pneumatic linear or part-turn actuators. The SIPART PS100 electro-pneumatic positioners modulate the valve according to the setpoint value. A hallmark of the SIPART PS100 is its low consumption of air. Thanks to the piezoelectric technology, compressed air is only required to move the valve. In the steady-state, consumption of air is negligible.
SIPART PS100 FEATURES:
- Fast commissioning at the push of a button.
- Simple operation via the display and four buttons.
- Display symbols according to NAMUR NE 107.
- Negligible air consumption in stationary operation.
- Setting the application profile based on predefined selection options, e.g., tight-closing valve, open/close valve, small valve.
- Fast response in end positions ensures short positioning times and tight valves.
- Insensitive to vibrations and steam hammer.
- Leakage compensation ensures a constant actual value and protects the actuator.
- Only one device version for linear and part-turn actuators.
SIPART PS100 INDUSTRIES:
- Power stations
- Paper and glass
- Water and wastewater
- Food and pharmaceuticals
Jordan Valve's Sliding Gate Seat Technology for Regulators and Control Valves
- Straight Thru Flow – The control element is perpendicular to the flow, resulting in less turbulence and superior trim life.
- Constant Contact in Seats – The disc and plate are in constant contact. Therefore, there is no valve ‘chatter’, less mechanical wear and greater stability at the low end of the stroke. The constant contact results in a self-lapping and self-cleaning action. Jordan Valve sliding gate seats wear in – they don’t wear out.
- Easy Maintenance – There is only one moving part in the Sliding Gate Seats. The seats are not pressed or screwed into place, so removal is easy. Cv values are interchangeable and control valve action is easily changeable.
- Short Stroke – In regulators, this results in faster response to input signals, less droop (greater accuracy), and longer diaphragm life. In control valves, the short stroke of the sliding gate seat results in less packing wear. Additionally, smaller actuators can be used resulting in lighter weight, smaller envelope dimensions and less air consumption.
- Seat Materials – Jorcote is the standard seat material. Jorcote is harder than stainless steel and provides excellent wear, erosion, & galling resistance. It has a lower coefficient of friction than Teflon; providing higher pressure drop capability and less offset. Jorcote seats perform in temperatures from sub-zero to 550°F (288°C). These seats have been lab tested to 1,000,000 full stroke cycles in 70 psi steam and maintained ANSI Class IV leakage while displaying negligible wear.
- Disc Plate Overlap – The disc and plate overlap by 1/32” (0,8mm) around each orifice. This creates an area of closure, not line of closure, resulting in better shutoff for a longer period of time, reducing waste and lowering costs.
- Multiple Orifice Design – The multiple orifice design of the sliding gate seat dissipates the wear energy and downstream flow, resulting in longer trim life and quiet operation.
