1" Sanitary Manual Diaphragm Valve - 316L ASME BPE Stainless Steel

Sanitary Diaphragm Valves for High-Purity Process Piping Applications

• 3A Manual Diaphragm Valves
• 316L Stainless Steel for Fluid Contact
• Working Pressure 10 Bar
• EPDM Sealing: -20℃ ~ 135℃ (150℃ Max 20min)
• VMQ Sealing Optional

The 1" Sanitary Manual Diaphragm Valve has fluid contact parts made of 316L stainless material passed by ASME BPE standard which makes it corrosion resistant and suitable for hygienic use in important operating processes. Moreover, the absence of dead spaces in its construction makes it less prone to contamination.

Product Overview

The Eagle 3A Manual Diaphragm Valve has been designed to provide complete isolation of processes in aseptic and high-purity applications. The valve body is made from 316L stainless steel for all surfaces that come into contact with fluids, thus providing high-quality resistance to chemical cleaning products. The working of the valve includes a handwheel that moves a precise compressor via the diaphragm and forms a sealed unit. Because of the design scheme, this valve can be used in processes in the biopharmaceutical industry like sterile processes, WFI systems, and others.

Component Breakdown

Installation

In order to achieve the optimum drainability and ensure the self-draining ability of the dead-space-free design, it is important to install the valve at an angle as indicated. This will allow the entire fluid to drain properly during the CIP cycles while avoiding any buildup at the weir.

Frequently Asked Questions

What is a diaphragm valve used for?

The diaphragm valve is used to allow/disallow flow in sanitary processes that require pure product consideration during the process. It does so by using a membrane that fully blocks the passage of fluid when it is in the closed position. The diaphragm valve types are common in biopharma, food and drinks production, and aseptic vapor processing. The manual diaphragm valve works in cases where automation is not important, such as sampling, small batch operations, or seldom use for shut-off.

What are the disadvantages of a diaphragm valve?

The diaphragm valve presents several limitations. First, the diaphragm is a component that is subject to wear and therefore needs to be replaced from time to time, especially if the usage involves frequent opening and closing operations or aggressive cleaning products. Second, diaphragm valves can only be employed for low and medium pressures and temperatures compared to ball and globe valves; in practice diaphragms made of EPDM can be utilized at a maximum pressure of 10 Bar and temperature of 135°C. Lastly, diaphragm valves are not suitable for accurate throttling or careful flow modulation. The reason for these drawbacks is very clear in hygienic processing, since sterile isolation and cleanability are much more important advantages than the need for occasional diaphragm replacement.

What is the lifespan of a diaphragm valve?

The lifespan of a diaphragm valve body made of 316L stainless steel is estimated to be measured in decades since the metal parts generally outlast the lifespan of the process line. However, it should be stated that out of the entire valve body, it is only the diaphragm that can be considered a wear item with a limited lifespan, depending on the working conditions. If the working conditions are typical for hygienic processing with compatible chemicals and moderate cyclic work, the EPDM diaphragm can last between 12 and 24 months before being due for a replacement. In case of heavy-duty working conditions with many high-temperature SIP cycles, aggressive cleaning solutions, and rapid cycling the diaphragm can be replaced every 6 – 12 months. Eagle’s diaphragms are created so as to last 40% longer than the average industry diaphragm which leads to longer maintenance intervals and reduced downtime.

What is the difference between a diaphragm valve and a globe valve?

A diaphragm valve operates by having a flexible diaphragm positioned to cover a weir to ensure that fluids cannot leak inside. By contrast, a globe valve contains a metal plug that reaches the seat containing either a piece of metal or a composite material, as the stem of such a valve will need to be passed through a structure containing packing that is likely to leak and needs to be serviced. Diaphragm valves are identified as a more suitable option for applications of sanitary and aseptic nature due to the design of the valves, which can be cleaned easily, as there are no areas where deposited material can be trapped.
