Minidisc sanitary valve

DISCOVER WHAT THE MINIDISC SANITARY VALVE DESIGN MEANS
The superb simplicity of disc sanitay valve meeting shaft at 45° means the seat is unpierced, for the purest of product integrity. The 180° rotation angles the disc sanitary valve cleanly through the product flow so the sanitary valve opens without resistance and stays in place. Half a turn of the valve handle provides quick, positive, leak-free shutoff. An "OPEN - CLOSE" mylar label indicates the status at a glance. A simple twist of the accessory lock-handle transforms the MINIDISC® into a regulating valve, locking firmly into any desired position.

The MINIDISC® is truly easy to maintain. Made entirely of stainless steel, type 304 or 316, it dismantles without tools, in seconds, simply by opening the standard heavy-duty clamp. Only three low-cost elements ever need replacement: the seat and two stem "O" rings. Changing them is a snap. The two "O" rings on the disc shaft prevent the entrance of the product into the stem housing. Two leak detector holes alert operator of worn "O" rings.

To insure a wide variety of applications, diverse gasket materials are offered. The seat is available in Teflon, buna, silicone, EPDM and Viton® (surcharge). The standard "O" rings are buna or Viton®. Other elastomers, EPDM and silicone, are available on request. Innovative, yet time-tested, long lasting, sanitary and fairly priced, the MINIDISC® valve boasts a proven record in the field.

MAXIMUM IN-LINE FLOW PRESSURE
Valve Size 1 1/2", 2", 2 1/2"............................120 psi
Valve Size 3", 4", 6".........................................80 psi

NOTE: The MINIDISC® valve is installed with the product flowing against the flat disc (see arrow). If the product flow is reversed, the pressure resistance will be reduced.

flow control sanitary valves

Sanitary Valve

The type SCV85 and SCV89 flow control sanitary valves are well suited to automated control systems found in biotechnology, pharmaceutical and food processes. Common control sanitary valve uses are pressure, temperature and flow control in fermentation reactors; control of gas blankets in closed vessels; and catalyst, defoamer, and additive initiation.

• Manufactured in accordance with the 3A Symbol Council
• O-ring stem seal quick disassembly with clamps
• Choice of ends: butt-weld, Tri-Clamp
• Choice of 17 innervalves
• Choice of innervalve characteristics: linear, equal percentage, quick-open

Sanitary valve troubleshooting guide

Sanitary valve troubleshooting:
Erratic Control
• Oversizing causes cycling or hunting –recalculate size required
• Check operation of steam traps and or relief Sanitary valves down stream
• Check that Sanitary valve moves freely over its entire stroke.
• Check inlet pressure does not droop excessively under load
Insufficient flow
• Ensure isolation Sanitary valves are open fully
• Check upstream pressure
• Blow down strainers
• Check control valve opens fully. Could be insufficient signal pressure of diaphragm problem
Sanitary Valve Passing
• Check actuator preload adjustment
• Check for foreign matter in seat
• Check for seat/plug damage

Actuator Adjustment sanitary valve

The preload tension on the actuator sanitary valve should be adjusted so that the sanitary valve plug begins to lift at the correct signal pressure when the full process pressure is acting upon the plug. (Air to Open valve)
Adjusting Preload
1. With full process pressure acting on the sanitary valve, connect the air signal to the actuator and note at what signal pressure the sanitary valve plug begins to lift.
2. If plug lifts below the lower signal limit (3 or 6 PSIG depending upon range) screw valve stem out of the actuator stem. Apply air to the actuator so that the plug is not turning on the seat while making the adjustment.
3. If the plug does not lift until significantly over the lower signal limit screw the valve stem further into the actuator stem
4. Adjust the valve stem until the valve is shut off at 3 PSI signal but lifts just above this pressure.
5. Once adjustment is complete lock valve stem position using the two stem nuts. Note: A valve that has been set to lift at 3 PSI with full process pressure will lift at a considerably higher start pressure when the process pressure is removed.
