Pressure Valve Dosing Pump

Pressure Valve for Cleaning Agent Pump (Lely A4 & A5 Compatible)

Compatible with Acid/Brush Disinfectant (Black Pump) & Alkaline Detergent (Orange Pump)

Maintain the precise chemical dosing of your Lely Astronaut A4 or A5 with this high-performance Pressure Valve. This critical component is designed for the peristaltic pumping units that handle your daily wash cycles and brush disinfection.

In a robotic milking environment, the consistency of your cleaning agents is non-negotiable. This valve ensures that once the pump pushes the chemical through, there is no backflow or siphoning, keeping your titration levels accurate and your milking system hygienic.

Features & Benefits

• Dual-System Compatibility: Engineered to work seamlessly with both the Black Pump (used for Acid and Brush Disinfectant) and the Orange Pump (used for Alkaline Detergents).
• Chemical-Resistant Construction: Built from high-grade synthetic materials specifically tested to withstand the corrosive nature of concentrated dairy acids and heavy-duty alkaline cleaners.
• A4 & A5 Optimized: A direct technical match for the latest generations of Lely Astronaut robots, ensuring the correct opening pressure for efficient chemical delivery.
• Prevents Backflow: Acts as a reliable check-valve to prevent chemicals from draining back into the containers, ensuring the lines stay primed for the next wash cycle.
• Durable Seal: Features industrial-grade internal seals that resist "swelling" or hardening, even with 24/7 exposure to teat disinfectants.

Maintenance Tip

If you notice your robot is flagging "low chemical" alarms despite having full containers, or if your teat brushes aren't getting adequate disinfectant, it is often a sign that a pressure valve is stuck or clogged with crystallized chemical.

We recommend replacing these valves annually—or during your major service intervals—to ensure your CIP (Clean-In-Place) system remains 100% effective.
