Product Description
NUOMENG is able to provide solutions in terms of sanitary valves and pipeline engineering system for customers in different fields, including pharmaceutical and biotechnology, food and beverage, microelectronic and semiconductor as well as chemical industries.
Innovative Technology
Our products are widely applied in pharmaceutical, food and biotechnology fields. We set high standards for quality and devices designed, manufactured by or operated in our factory conform with the safety requirements in the aspect of sanitation and sterilization.
Surface Roughness
The standard requirement for the interior surface roughness of aseptic diaphragm valves is Ra ≤ 0.4 μm. But we can also realize Ra ≤ 0.8 μm and Ra ≤0.25 μm if customers have specific requirements.
All surfaces can be electropolished to even reduce the roughness.
If diaphragm valves are to be applied in pharmaceutical, semiconductor, microelectronic and new chemical industries, the valves have to be aseptic and stainless steel to make sure the media is extremely purified. Thus, aseptic stainless steel diaphragm valves, whose design enables them to sterilize and pasteurize the medium, can be applied to process WFI, ultra-purified chemicals, intermediate or final products in pharmaceutical, biotechnology and food industry.
Elastic Diaphragm Advantage
The diaphragm is evenly fixed in PTFE with a screw.The elastic PTFE diaphragm facilitates an even flow and allows for subsequent replacement of the diaphragm yet without replacing the actuator.
Soft elastic diaphragm--- EPDM
Soft elastic diaphragm consists of a mixture of EPDM rubbers. The mixtures have been vulcanized so that the diaphragm can be safely used even at high media temperatures.
Application:
RG diaphram valve is a series of sanitary diapgram valve, it is widely used on wine, dairy products, beverage, food industry, pharmacy etc. Achieving the requirement of control and open/close for the pipeline system.
We test diaphragms in our in-house test bench, including special cycle tests required in the pharmaceutical industry.
WORKING PRINCIPLE:
The diaphragm is close under normal state, and that moment the diaphragm clung to the valve body cavity, and closing off the flow path through the pipeline. When the diaphragm valve have the requirment to clean or open. The valve stem moves upwards according to the manual or pneumatic actuator equipment, spherical diaphragms naturally bend upwards, so that the valve is open and reach the requirement of clean and open. The diaphragm make the lower body cavity and the upper chamber separted from the valve cover, so that the stem at the top of the diaphragm, disc media and other parts from corrsion, eliminating the need for packing structure, and no media leaks.The optimize valve body made the cleaning liquid flow out totally, so that don't have any entrapment.
