Product Description

EPDM Repair Kit for Bürkert 6213 1" DN25.0 Valve (SKU: 00646956)

Original Service Kit for Cold Water Solenoid Valves in Touchless Car Washes

Original factory replacement diaphragm repair kit made of high-grade EPDM rubber, designed for brass Bürkert Type 6213 solenoid valves with a 1" (DN25.0) connection size. This service kit is specifically tailored for repairing solenoid valves operating with cold water and mild chemicals in self-service car wash hydraulic installations. Replacing worn internal components (diaphragm, spring, plunger/armature) restores full sealing performance and reliable operation without the need to replace the entire expensive brass valve body. The product is fully compatible with brass solenoid valves under part numbers ELE-BKF-323679 and ELE-BKF-267794. Explore our complete offering in the solenoid valves and repair kits category or read our expert guide on choosing solenoid valves for touchless car washes.

Key Benefits & Technical Features of the Bürkert 00646956 Repair Kit:

  • High-Grade EPDM Diaphragm: Premium EPDM rubber provides excellent elasticity and superior resistance to hot and cold water, as well as standard car wash detergents.
  • DN25.0 (1 Inch) Sizing: Engineered specifically for servo-assisted valves with a full DN25 orifice, guaranteeing a 100% precise fit and reliable sealing of pilot channels.
  • Complete Maintenance Set: The kit includes all essential wear components (diaphragm assembly, return spring, and plunger/armature with rubber seal) for a fast and thorough valve rebuild.
  • Restores Full Functionality: Replacing the diaphragm solves common valve issues such as internal leaks in the closed state (dripping programs) or failure to open/close when energized.
  • Prevents Seasonal Failures: Regular servicing of solenoid valves is essential to avoid costly car wash downtime. Read our tips on preparing your facility for harsh weather conditions in our winter car wash preparation guide.

Frequently Asked Questions (FAQ)

Which solenoid valve models are compatible with this repair kit?
Repair kit part number 00646956 is designed for brass Bürkert Type 6213 solenoid valves with a 1" (DN25.0) port size. In BKF car wash systems, it is fully compatible with cold water valves under part numbers ELE-BKF-323679 and ELE-BKF-267794.
What are the typical signs of a damaged or worn diaphragm in a Bürkert 6213 valve?
Common signs of a worn or hardened EPDM diaphragm include water passing through the valve when it should be closed (constantly leaking wash program) or delayed opening/closing response. A torn diaphragm can also prevent the system from building up pressure.
Why choose an EPDM material diaphragm for car wash applications?
EPDM rubber offers superior resistance to continuous exposure to cold and hot water as well as mild car wash chemical solutions. It provides excellent elasticity and fatigue resistance under high-frequency opening and closing cycles.
Are specialized tools required to install this repair kit?
No. Basic hand tools (a wrench/socket to undo the valve housing bolts) are sufficient for rebuilding the valve. Always turn off the water supply and disconnect electrical power from the solenoid coil before starting maintenance.
Does this kit include the electrical coil or the brass valve body?
No, this product is an internal maintenance service kit containing the diaphragm assembly, return spring, and plunger/armature. Electrical coils and brass valve bodies are sold separately.
