Product Description P/N: 145407DR
Description
The Danfoss Airflex 145407DR is a high-performance pneumatic quick release valve designed to rapidly exhaust pressurized air from industrial clutch and brake assemblies. Operating with a high flow capacity of 172 cubic feet per minute, this 1/2-inch valve utilizes a specialized rubber sleeve to respond instantly to pressure drops, ensuring the immediate disengagement of mechanical drives. By preventing clutch drag and reducing friction, the valve significantly extends the operational lifespan of heavy-duty pneumatic machinery.

Information About 145407DRBCM-MS/TP
The 145407DR is an integral pneumatic component belonging to the renowned Airflex series, originally developed by Eaton and now manufactured by Danfoss. It is constructed from a durable zinc alloy to withstand harsh factory conditions and features an integrated muffler to reduce exhaust noise during rapid venting cycles. Maintenance technicians and mechanical engineers deploy this quick release valve (QRV) directly onto clutch or brake ports to minimize air travel distance, achieving near-instantaneous exhaust response times. The unit is engineered for exceptional longevity, offering a mean life of five million cycles under standard operating conditions, making it ideal for high-cycle automated manufacturing processes.
Key Features:
● Rapid Air Exhaust: Discharges pressurized air almost instantaneously to ensure the quick, complete disengagement of pneumatic clutches and brakes.
● Integrated Muffler: Includes a built-in silencer to effectively reduce sudden pneumatic exhaust noise, improving safety and comfort on the factory floor.
● Rubber Sleeve Mechanism: Utilizes a highly responsive internal rubber sleeve that shifts instantly upon a drop in line pressure to open the exhaust port.
● Durable Zinc Alloy Body: Constructed from rugged zinc to resist mechanical wear and withstand continuous heavy-duty use in industrial environments.
● High Flow Capacity: Delivers an impressive 172 CFM flow rate to evacuate high-volume air chambers rapidly without causing pneumatic bottlenecks.
● Extended Cycle Life: Engineered to reliably perform up to five million cycles at standard operating pressures, minimizing the need for frequent replacement.
The 145407DR delivers the reliability and pneumatic precision required for immediate mechanical disengagement and continuous efficiency in heavy industrial automation.
