Walvoil VDSRL Direct Acting Sequence Valve – 1/2" BSP, 50 L/min, 50-200 Bar, Aluminium
Walvoil VDSRL 10-12/TS.S direct acting sequence valve is a robust and reliable solution designed for controlled hydraulic flow sequencing in mobile and industrial systems. It ensures that a secondary hydraulic function is only activated once the required pressure has been reached in the primary circuit.
Built with an aluminium body, this valve provides a strong combination of durability and reduced weight, making it well suited to demanding hydraulic applications. Its direct acting design offers dependable pressure control and efficient sequencing performance across a wide range of systems.
With a nominal flow rate of 50 l/min and a maximum operating pressure of 210 bar, the VDSRL 10-12/TS.S is suitable for higher flow hydraulic circuits. It also features an adjustable pressure setting range of 50–200 bar, allowing flexible setup to meet different application requirements.
