This is a relief valve having a compact design with high rigidity for general oil pressure which can be used for comparatively small flowrates. The difference between all pressure and cracking pressure is very small. It has almost same performance as balance piston type.

Adoption of a viblation-proof design prevents chattering from developing at the time of high pressure.

Possible to make adjustment in a wide range. It is very easy to make adjustment on pressure at the time of low pressure.

Holding the increase in pressure due to rise of temperature, stabilization pressure can be made.
