HYGIENIC SINGLE SEAT SAMPLING VALVE

IMPLEMENTATION
Unique Sampling valve is a single seat valve that is designed to conduct sterilization process before and after each sample. Valve body and fittings are manufactured from monoblock material to avoid cracks and problems related to welding.

OPERATION PRINCIPLES
Sterilization: When the valve is closed, the channel between the valve paths is opened for sterilization. If steam is used, placing a small safety valve (optional) on the outlet is recommended.
Sampling: When the valve is opened, the body and membrane gasket is withdrawn and allows the passage of sample.

STANDARD DESIGN
The valve consists of three parts: valve body, one actuator and membrane gasket. Rubber membrane gasket is located on the body of the actuator and acts as a stretchable plug. The valve bodies and actuators may be relocated.  In the event that single seat valve, valve or actuator is changed using a renewal package, it can be converted to a dual-seat valve.

TECHNICAL DATA

Temperature
Temperature Range ........................................ 1 °C - 130 °C

Maximum Sterilization Temperature
Dry steam (2 bar) ............................................ 121 °C


The steam should be dry because condensed water damages the membrane gasket. It is recommended to replace the membrane gasket after each 500 processes of sampling/sterilization, depending on the operating conditions or experience.

Pressure
Max. Operating pressure ................................ 600  kPa (6 Bar)
Min. Operating pressure ................................. 0 kPA (0 Bar)

PHYSICAL DATA

Materials
Valve Body............................ 1.4404 (316 L)
Actuator................................ 1.4301 (304), 1.4404 (316 L)
Membrane gasket ............... EPDM, silicone














Valve Consists of Three Different Sizes:

SIZE 4:     For low-viscosity products such as water, wine and milk
                 Up to 100 cp viscosity, maximum particle size: 2.5 mm

SIZE 10:   For high-viscosity products such as fruit yogurt, syrup and ice cream.
                 Up to 1000 cp viscosity, maximum particle size: 7mm

SIZE 25:   For high-viscosity products such as jam.


Valve Bodies
• Tank (Welded Connection)
• Pipe Liner (Welded Connection)
 • Clamped


Valve heads
• Handle
• Pneumatic Actuator (5-8 bar air supply)




VALVE CLOSED
Closed Valve: When the valve is closed in the
“sterilization position”, the channel between the
valve paths is opened for sterilization.





VALVE OPEN
Open Valve: When the valve is opened in the
“Sampling position”, the body and membrane
gasket is withdrawn and allows the passage of sample.
