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.
NUOMENG Technical Team tries to make sure that all necessary technical support is provided for every customer. To shorten the lead time, a countrywide distribution network and abundant inventories have been established. Meanwhile, we are constantly making improvements to optimize existing products and develop new products. Last but not the least, we are able to customize professional solutions according to different requirements of working conditions.
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. For forged products, the requirement of exterior surface roughness is not that rigorous. It only has to realize Ra ≤ 0.8 μm or Ra ≤ 0.4 μm.
All surfaces can be electropolished to even reduce the roughness.
Recent years have seen some great improvements in the purity and quality of food and pharmaceuticals in China, and more strict regulations and approval requirements have been established. We are proud to be a part to make those improvements happen.
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.
NUOMENG is equipped with state-of-the-art equipment and a motivated service team, thus our clients can always get the best services. Our years of experience and in-depth dialogues with factory operators allow us to continue to optimize the design of diaphragm valves and their individual components.
We test diaphragms in our in-house test bench, including special cycle tests required in the pharmaceutical industry.
Different mounting positions and working conditions will require different valves or diaphragms. In particular, the chemical properties and temperatures of working media can lead to different interactions.
Working principle: The diaphragm is close under normal state. When the diaphragm valve have the requirment to clean or open by pneumatic operation by pneumatic actuator, the valve stem moves upwards according to the manual or pneumatic actuator equipment, spherical diaphragms naturally nemd upwards.
Intelligent electric valve positioner is a regulator that can control the open range of valve through receving external input setting signal or internal manual setting signal. It used PID arithmetic and PWM control technology to achieving control flow precisely. The advantage of Intelligent electric valve positioner are that has remote automatic control system.
Advantage: The optimize valve body made the cleaning liquid flow out totally, so that without any entrapment.
Pneumatic Tank Bottom Diaphragm Valve
Application:
RG diaphram valve is a series of sanitary diapgram valve, it is widely used on wine, dairy products, beverage, foodstuff industry, pharmacy etc. Achieving the requirement of control and open/close for the pipeline system.
Work principle:
The diaphragm is close under normal state, and that moment the diaphragm clung tho 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 nemd 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.
