This is a specialized non-return valve, featuring a unique "star lid" design, engineered for milking machines. Manufactured by the Open Door brand, its primary function is to ensure unidirectional flow within the milking system, preventing crucial fluids or vacuum from flowing backward. This valve is a key component for maintaining hygiene and operational efficiency, contributing to a smooth and safe milking process.
Features
:- Prevents Backflow of Milk: This is the most crucial function. When the vacuum in the milking cluster changes (e.g., during pulsation, cluster fall-off, or when the machine is shut down), the NRV ensures that milk collected in the bucket or pipeline does not flow back into the vacuum line or, more critically, back into the animal's udder. This is vital for hygiene and preventing mastitis.
- Maintains Vacuum Stability: By preventing air from entering the system through the milk line when flow stops or fluctuates, the NRV helps maintain a consistent vacuum level, which is essential for efficient and gentle milking.
- Protects Vacuum Pump: Backflow of milk or moisture into the vacuum pump can damage it, leading to costly repairs. The NRV acts as a barrier, protecting the pump from contamination.
- Ensures Hygienic Operation: By preventing milk from flowing into areas where it shouldn't be, it reduces the risk of bacterial growth and contamination within the milking system.
