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.

Advice

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.

Product

Production name: Stainless steel pneumatic diaphragm valve with explosion-proof returne.
Description:The valve is driven by pneumatic, the cylinder block is 304, which is suitable for inert, corrosive liquids and gas media. With explosion-proof solenoid valve and explosion-proof return device, compared with ordinary stainless steel pneumatic diaphragm valve has explosion-proof function, can be used in the required environment.
Application:  Stainless steel pneumatic diaphragm valve with explosion-proof returner.Comparing with the ordinary pneumatic diaphragm valve which have explosion-proof function,can be used in the environment with explosion-proof requirements
Flexible Connection Options: clamp, weld and flange connections.
Standard Design Excellence: Adhering to Standards: DIN, 3A, SMS, ISO and more, ensuring universal applicability and superior quality.

Work 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 requirement to clean or open,the valve stem moves upwards according to the manual or pneumatic actuator equipment,spherical diaphragm 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 separated from the valve cover,so that the stem at the top of the diaphragm,disc media and other parts from corrosion,eliminating the need for packing structure,and no media leaks.The optimize valve boby made the cleaning liquid flow out totally,so that don't have any entrapment.
