• The QJ-VR and PTC-VR line of variable rate fertilizer assemblies feature a variable diameter orifice that produces a wide range of flow rates—its like having several metering orifices in one.
• Allows for a wider range of ground speeds and/or application rates from a single size for improved productivity.
• Also ideal for variable rate prescription map applications.
• Both QJ-VR and PTC-VR are ideal for installation on planters and toolbars for liquid fertilizer metering and application.
• PTC-VR features nylon construction for excellent strength and chemical resistance.
• QJ-VR features acetal and nylon construction with choice of nylon or stainless steel hose barbs for strength and excellent chemical resistance.
• Simple, elastomer (EPDM) variable orifice for reliable, long-term operation.
