Pneumatic Satinless Steel Mixproof Valve
Material of valve: AISI304, AISI316L
Standard of valve: DIN/SMS/3A/ISO/IDF
Flux domination of pipeline: DN25-100&1"-4", applied to the stainless steel pipeline system
Medium: Beer, Dairy, Beverage, Pharmacy. Applications:
The mixproof valve is a completely hygienic double sealing valve.
This system allows for the simultaneous processes in the two bodies of the valve by providing interface between the two fluids, preventing the possibility of product contamination.
The leakage chamber and leakage detector can be self cleaned through seat lifting.
The mixproof valve is applied to food-processing industries, especially in the beverage and diary industries.
Operating principles:
Lift type mixing proof valve is remotely operated through
Compressed air. It is normally closed before running.
The mixing proof valve is constructed with two independent
Plugs, which will form a leakage chamber that interlinks to
Atmosphere under normal working status. When occasional
Failure of the medium leakage happen, medium will flow into
The chamber and be discharged at the out port.
The leakage chamber is closed when the valve is operating. So medium can flow through one pipeline to another. This valve can be clean in place. Many options of CIP and SIP combinations are available to users. (Refer to cleaning sterilization function options)
Clean system can clean the upper, lower stem and leakage chamber. Which ensures the valve to be high hygienic. Effectively cleaning system makes the fluid that special for CIP clean in place directly wash all the inside valve body. The cleaning system commoner, it will take shorter time. Another beneficial of the high cleaning system is that the lift type mixing proof valve can be applied to aseptic processing.
If user's steam into CIP pipeline, the system will constitute a shield that can isolate air...
