Parker's innovative VA450 mobile valve is the result of many years of experience in mobile hydraulics and load-sensing directional control valves. It offers industry-leading performance, controllability, and energy efficiency. The VA450 is precision manufactured with high-grade materials.

The VA450 the largest valve in the VA-series and is a highly customizable and flexible valve that can be integrated into simple as well as advanced hydraulic system solutions. With a wide variety of combinations in terms of valve functionality, we can offer a solution optimized for any function in the machine

In our endeavor to develop an energy efficient valve with market-leading performance and high precision, we have used our extensive knowledge of load-sensing technology to design function-adapted spools, pressure compensators and load signal pressure limiters. This has enabled us to significantly reduce energy losses and increase productivity. Actuation can be hydraulic or electrohydraulic, each with optional manual lever control, in any combination in the same valve.

For complete customization of functions and to meet all conceivable requirements in terms of auxiliary function control, the VA450 can be combined with tailor-made function manifolds consisting of components from the comprehensive Parker product range
Features & Benefits
• Modular design with a wide variety of functions and combination possibilities to meet any need, yet service-friendly to simplify maintenance and repairs.
• Pre-compensated, load-independent flow control with function-adapted main spools gives the operator precise control of the machine to increase productivity.
• Improved energy efficiency through optimal channel design, LS pressure limitation, active tank gallery refilling and carefully engineered function-adapted spools reduces emissions.
• The proven design of the VA450 is built to withstand harsh environments.
• Seamless integration of function manifolds designed specifically for customer-specific requirements to reduce the number of components and simplify the hydraulic system.
