Burkert Diaphragm Valves (Pneumatic/Manual) - Single/Double Membrane Diaphragms, FDA Certification. Burkert Diaphragm Valve Diaphragm Leakage Causes and Improvement Solutions. In China, the food, beverage, and biopharmaceutical industries almost universally use Burkert diaphragm valves from Germany due to their hygienic design and FDA certification.
Burkert Fluid Systems manufactures many types of hygienic process control diaphragm valves, including pneumatic, manual, multi-channel, tank bottom, sampling, and T-type valves. The core component of a Burkert diaphragm valve is the diaphragm itself.
We frequently encounter problems such as diaphragm leakage, poor sealing, severe wear, and cracked or dented diaphragms.
Today, we will analyze in detail the causes of diaphragm leakage in Burkert diaphragm valves and how to customize solutions to address this issue.
- Improper Burkert diaphragm selection: The selection of the Burkert stainless steel diaphragm valve's sealing material, the Burkert diaphragm, must consider the fluid medium's temperature and the strength of its acidity or alkalinity. For example, if the user's equipment pipeline has a fluid medium temperature of 100-180℃, and the selected Burkert diaphragm valve uses an EPDM single diaphragm that is only resistant to temperatures below 90℃, this type cannot withstand high temperatures and strong acid/alkali corrosion, leading to seal damage and severe leakage after only a few months of operation.
- Aging and loss of elasticity in the packing: Frequent valve operation causes packing wear.
- Improper selection of packing material and type: For example, using Burkert PTFE diaphragm packing in 200℃-250℃ conditions can cause slight creep under prolonged operation at critical conditions, and the sealing performance decreases under high pressure. Similarly, using woven packing for highly permeable media such as liquid ammonia, tar, and fuel oil can easily lead to leakage under high temperature and pressure.
- Improper packing installation: After the packing is installed in the stuffing box, axial pressure is applied through the gland. Due to the plasticity of the packing, it generates radial force and comes into close contact with the valve stem. If the packing is tight at the top and loose at the bottom during installation, uneven force will cause the packing to loosen, resulting in packing leakage. Burkert diaphragm valve diaphragm leakage improvement solutions:
- Burkert stainless steel diaphragm valve diaphragms improve the surface precision and cleanliness of the valve stem and packing, reducing the friction coefficient between various components.
- Select a suitable Burkert diaphragm that can resist temperature changes and meet the physical and chemical properties of the medium. For example, for high temperatures and strong acids and alkalis, choose a German Burkert double diaphragm PTFE+EPDM;
- For weak acids and alkalis at room temperature, a Burkert single diaphragm EPDM is sufficient.
- When installing Burkert diaphragm packing, the method must be correct. Add packing one ring at a time, pressing and tightening each ring to ensure even force distribution on the packing.
- For Burkert diaphragm valves with spring action and PTFE V-type packing, the gland screws should be tightened as symmetrically as possible, and should not be skewed.

Plain language sourcing guide for Burkert diaphragm valve pneumatic | manual Burkert diaphragm single diaphragm double diaphragm
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.
