Applications
PW aseptic sampling valves must be treated by Sterilization-In-Place (SIP) processing before and after sampling each time. Materials are sealed with diaphragm directly. There are no dead ends for cleaning and the valve can be sterilized more thoroughly. It can carry out continuous aseptic sampling at any time. It is widely used in the wine, beverages, diary, and pharmaceutical industries.

Operating Principle

Sampling:
Before sampling, PW aseptic sampling valves must be treated by Sterilization-In-Place (SIP) process. Open the valve by rotating the handle (adjustable valve) or the switch actuator (on/off valve). The valve shaft core and diaphragm should open, and the liquid can pass through.

Sterilization after valve is closed:
Close the valve by rotating the actuator in the opposite direction, and meanwhile keep the channel between two hoses unblocked. Then the sterilization (SIP) is carried out again.

The maximum sterilization temperature (seal material: EPDM) for dry steam (2-3bar) is 135°C -150°C, with a time limit of less than 20min. The steam must be dry, because the condensation water may damage the diaphragm. We suggest that you should replace the diaphragms after every 100 sampling operations or sterilization operations, or you can replace them according to your experience or working conditions.

PW aseptic sampling valve have two configurations.

PW-1 type is manually operated with fast-open structure. It consists of a valve body, a valve head, a handle, and a diaphragm. Rubber diaphragm is placed in the shaft core of the valve head, and used as a ductile valve core. The valve body and valve head are both replaceable.

PW-2 type is manually or pneumatically operated with fast-open structure. It consists of a valve body, a valve head, an actuator, and a diaphragm. Rubber diaphragm is placed in the shaft of the valve head, and used as a ductile valve core. The majority of manual and pneumatic components are replaceable, and pneumatic valve can be equipped with a fast-open handle.
