The primary objective of this study is to developed shuttle valve having microscopic groove for smooth and quick operation. Generally shuttle valve are controlled both sides, microscopic groove of developed shuttle valve in this study ensured open-close smoothly and quickly. The test for performance of development shuttle valve is noise test, durability test, pressure test and leakage test. The dB(A) levels of noise test was closed background noise. The durability test was gave load pressure of 2.0 kgf/cm² for 15,000 cycles. The press test was loaded press(1.5 times of maximum allowable pressure) for 15 seconds. And the leakage test was loaded press(1.1 times of maximum allowable pressure) for 15 seconds. The results of these test are showed excellent performance, and performance of developed shuttle valve in this study was verified sufficiently.
