VICKERS-4CK301P3

Poppet designs are well suited for backflow prevention because they seat cleanly and hold pressure without a lot of leakage past the valve. The 4CK301P3 runs a low spring setting, which keeps pressure drop across the valve minimal during normal flow conditions. For a harvester circuit dealing with backflow problems, that combination of reliable seating and low hysteresis is generally what you want. The valve is rated up to 350 bar and handles flows up to 30 litres per minute for this particular unit, so as long as your circuit falls within those parameters, it fits the application category this valve was built for.

High operational efficiency and consistent performance across varying flow conditions is what it's designed for. It should be a dependable choice when backflow prevention and pressure integrity are critical.
