Yuken Direct Type Relief Valves

These valves are small and have a simple structure for their capacity. However, they are likely to exhibit high- pressure override (a pressure characteristic observed when a fluid starts flowing from a valve and reaches the rated flow rate) and chattering. Therefore, they are used to control the pressure of relatively small flows, as shown in Fig. 3.2. Valves of the size 1/8, in particular, are very popular for pilot pressure controls.
