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.
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.
Elastic Diaphragm
The diaphragm is evenly fixed in PTFE with a screw. Compared to clamp connection, the biggest advantage of using a screw is that the screw transfers the force evenly to a large area of the flange, which prevents damage to the mechanical connection between diaphragms, especially under vacuum operating conditions. The elastic PTFE diaphragm facilitates an even flow and allows for subsequent replacement of the diaphragm yet without replacing the actuator.
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. The diaphragms are equipped with different technical characteristics depending on the mixture used and the processing conditions, such as the crosslinking process, vulcanization temperature and pressure. Soft elastic materials conforms to the following principle: the higher the temperature the load capacity, the shorter the service life and the smaller mechanical stress. Therefore, the temperature load and deformability of the diaphragm must be optimally adjusted to the actual application. Different structural designs are available to achieve this. Features of Soft Elastic Diaphragms include: in the event of mechanical contamination, passage of highly insensitive working media, such as cellular agglomerates, solid matter or catalytic solid matter, and slurries, generally does not affect the function of the valve or the sealing on the valve barrage. Different EPDM compounds can be selected based on different operating/sterilization temperature and chemical properties of the working media.
Our PTFE diaphragm (TFM1700) is known as the second-generation PTFE diaphragm. It offers maximum chemical resistance. Even under steam conditions, PTFE diaphragms wear much slower than soft elastomers. When the medium is hyperosmotic, a moderately larger bond is required for PTFE materials. Compared to normal diaphragms, PTFE diaphragms are softer and more elastic. Due to the higher rigidity of the work under high cyclic loads, the service life of the diaphragm may be shortened depending on the actual applications.
During the production of diaphragms, every process is strictly controlled. A random sampling of finished products completes a comprehensive testing cycle.
Raw materials are sourced only from selected suppliers, which are thoroughly tested in our in-house laboratory or external certification bodies. Raw materials are stored under controlled conditions.
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.
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
