VK4-8303-652-5-16

The Schneider Electric VK4-8303-652-5-16 is a 3-way globe valve assembly designed to handle complex fluid control applications with efficiency. Measuring 6 inches in size, it provides a high flow coefficient of 500 Cv, allowing substantial flow rates through the system. The valve operates using a pneumatic spring return actuator coupled with a positive positioner, specifically the MK-6911 and AK-42309-500 models, which enables accurate positioning and control.

The actuator’s spring range varies from 5 to 10 psi, ensuring reliable performance under different operational conditions. This assembly has a close-off pressure rated at 35 psi (241 kPa) and is capable of withstanding a maximum operating differential pressure of 35 psi (241 kPa). Its design adheres to ANSI Class 125 pressure class standards for robust performance.

An impressive operating temperature range from -7 to 138 degrees Celsius further elevates its applicability in varying environments, affirming its versatility in numerous applications. Structurally, the valve features a body made of cast iron, while the seat is manufactured from forged brass, providing durability and enhanced thermal resistance. The stem is crafted from stainless steel, adding to the assembly's longevity.

The flow mechanism is based on the equal percentage type, characterized as modified linear diversion, and enables effective mixing and diverting action. This feature allows the VK4-8303-652-5-16 to adapt fluid routes based on system requirements, making it a reliable component of modern fluid management systems.
