5/8" Vacuum Shut-off Valve – Vacuum Operated N.C. (Normally Closed) Installed between the milking unit and the Milk Meter. In the presence of vacuum in the milk line, the valve remains closed; applying vacuum to the control inlet opens the valve, enabling milk flow. The primary advantage of the diaphragm valve is that the hose is not compressed during operation, preserving its internal diameter and flow capacity. The body is crafted from a durable transparent polymer, allowing for visual monitoring of the milk flow. The cover and control mechanism components are made of reinforced polypropylene, ensuring durability and resistance to operational stress. The valve diaphragm requires regular replacement (recommended at least once a year or according to wear, per manufacturer guidelines). Connection to the air line is made via a quick coupling, simplifying installation and maintenance. Supplied as a set of two valves. 5/8" Vacuum Shut-off Valve – Vacuum Operated N.O. (Normally Open) Installed between the milking unit and the Milk Meter. In the presence of vacuum in the milk line, the valve remains open; applying vacuum to the control inlet closes the valve, shutting off the milk flow. The key benefit of the diaphragm design is the elimination of milk hose compression during operation. This preserves the internal diameter and prevents the wear and tear typical of mechanical clamping systems. Construction and Materials:
The transparent body made of durable polymer ensures visual control of the milk flow.
The cover and control assembly parts are made of reinforced polypropylene, resistant to stress and chemical exposure.
The diaphragm is subject to scheduled replacement at least once a year (or more frequently, depending on operating conditions).
Connection to the air line is executed via a quick coupling, facilitating easy installation and service.
Packaging: Supplied in a set of two valves. 5/8" Vacuum Shut-off Valve – Pneumatically Operated N.O. (Normally Open) Installed between the milking unit and the Milk Meter, ensuring reliable flow control in automated milking systems. In the presence of vacuum in the milk line, the valve remains open; applying compressed air to the control inlet closes the valve, shutting off the flow. This design ensures a more stable process that is gentle on the equipment. The main advantage of the diaphragm valve is the absence of milk hose compression during operation, which preserves the internal diameter, reduces wear, and ensures a constant milk flow. Design Features:
The transparent body made of durable polymer allows for visual monitoring of the milk flow.
The cover and control mechanism components are made of reinforced polypropylene — a material that is durable and resistant to chemical exposure.
The diaphragm is subject to scheduled replacement at least once a year (or more frequently, depending on operating conditions).
Connection to the air line is executed via a 6 mm quick coupling, simplifying installation and maintenance.
