Burkert's manual/pneumatic diaphragm valve series includes models 2030, 2031, 3232, and 3233, commonly used in the biopharmaceutical industry. These valves are used in Burkert diaphragm valves, pneumatic diaphragm valves, manual diaphragm valves, and tank bottom valves. The double diaphragm is sanitary grade and FDA certified.
It is suitable for applications involving high-temperature steam sterilization and large instantaneous temperature differences. Burkert diaphragms are not easily deformed, have a timely opening and closing response, and are corrosion-resistant and wear-resistant.
In response to demand from our long-term customers in the biopharmaceutical equipment industry, we have stocked the following Burkert diaphragm valve models: Burkert DN25 double diaphragm 677677, DN15 double diaphragm 677675, and DN20 double diaphragm 677676.
Burkert diaphragm valves use imported reinforced silicone rubber for the diaphragm, and the valve body undergoes high-speed precision machining and polishing, achieving a surface finish of Ra0.2um. They are sterile, pore-free, and widely used in systems with high sterility requirements in the biological, pharmaceutical, and electronics industries.
Widely used in the beer, beverage, and biopharmaceutical industries, German Burkert diaphragm valves are renowned for their long service life, low maintenance costs, and the ability to be customized to meet specific customer application requirements.
These include Burkert pneumatic diaphragm valves, Burkert manual diaphragm valves, and Burkert electric diaphragm valves, all of which are of excellent quality. In terms of both product quality and service life, they are much better than the German GEMU diaphragm valves.
In actual use, Burkert diaphragm valves can generally last for five or six years without breaking down.
Only the sealing component, the Burkert diaphragm sheet, needs to be replaced every few years.

The BURKERT membrane series includes the following five basic types, each with different characteristics to meet various application requirements: EPDM Membranes (AD): These membranes have good elasticity and are made of ethylene propylene diene monomer rubber, suitable for sanitary applications.
FKM Membranes: These membranes are made of fluororubber, especially suitable for water treatment applications. PTFE Membranes (EA): These membranes are made of polytetrafluoroethylene (PTFE/EPDM), and due to their chemical inertness and low chemical activity, they are especially suitable for sanitary processes and the chemical industry.
Advanced PTFE Membranes (EU): These membranes are made of second-generation polytetrafluoroethylene, with improved mechanical properties, suitable for applications with large temperature variations. GYLON diaphragms (GYLON/PTFE laminated, abbreviated ER): GYLON diaphragms are made of polytetrafluoroethylene (PTFE) using a special process.
Compared to ordinary PTFE products, they have "cold-plastic processing" properties; they maintain their original shape after four bending strength tests. They are ideal for sanitary applications. Please note: Burkert diaphragms are optimized and certified for use only with Burkert diaphragm valves.
Using diaphragms from other manufacturers with Burkert valves is not recommended, as we cannot guarantee proper functioning. Burkert diaphragm certifications: FDA; EC; USP; 3-A Sanitary Standards. For more information on Burkert diaphragms and diaphragm valves, please contact us!
Plain language sourcing guide for Burkert double-layer membrane DN20 EPDM/PTFE 677676
Start with the full model name. Check the brand name. Check the part number. Check the code on the old unit. These small checks help you avoid a wrong order.
Take one clear photo of the front label. Take one photo of the side label. If the part has a cable, plug, port, seal, coil, or screen, take a photo of that area too.
Tell us the quantity you need. Tell us your country. Tell us the date when the plant needs the part. We can then check stock, lead time, safe packing, and the best shipping plan.
If the exact model is no longer made, do not guess. Send the old model and the use case. LEHIY can compare close options and explain which choice is safer for repair work.
Use simple order notes. Write the model in one line. Write the quantity in one line. Write the delivery country in one line. This helps our team reply faster.
Check the old part before removal. Look at the label. Look at the connector. Look at the mounting size. Look at the voltage or pressure rating if it is shown.
Do not rely on a short nickname for a part. Many industrial items have close versions. A small suffix can change the plug, output, range, or software setting.
Ask for a stock check if the plant is stopped. Ask for a lead time if the order is planned. Ask for packing photos if the part is fragile or heavy.
For a replacement order, tell us what failed. Tell us where the part is used. Tell us if an equal model is acceptable. This makes the first answer more useful.
For repeat orders, send the last invoice, old label, or old packing photo. The same reference can help us match the correct product again.
For urgent service, keep the message simple. One model, one quantity, one photo, and one delivery target are enough for a fast first check.
