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
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.
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.
The diaphragm is a consumable part. They need to be inspected and replaced regularly, or it could cause malfunction, potentially leading to a dangerous situation. Please note: maintenance intervals for inspection and replacement of diaphragms are application dependent. Responsibilities must be considered when determining appropriate maintenance intervals, maintenance history, and stress placed on parts due to frequent sterilization or frequent cycling.
Due to natural aging of plastics and elastomers, we recommend observing storage conditions and closing off diaphragms, so that a maximum storage space and the service life of diaphragms can be guaranteed

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.

Standard Design:
Standards:DIN,3A,SMS,ISO/IDF,BS/RJT,ASME/BPE etc.
The parts of valves :an actuator,diaphragm and body which assemble together with bolts and nuts.The entire valve assembly in meticulously.The actuator can be manual and pneumatic,the diaphragm made of  artificial rubber which can have all kinds of soft and hard degree.The body can be two way or three way
Connection:Weld ,Clamp ,

Material:
Steel componens: stainless steel 304,stainless 316L

Seal: EPDM+PTEE the seals are imported seal material (which conform to the FDA177.2600standard). With Riter unique technology ,will be a bolt coupling nut with EPDM/PTEE perfect combination into a whole sealing parts. the sealing parts contact with the media of the parts of the PTEE material has good cold resistance(-25 degree)excellent heat-resistance(+250degree) of all sors of chemical preation is well toleratd and excellent wear resistance to flow .
