Please have a look at this circuit and see if you can give me some advice. The device labeled 2 is the one in question. This is a valve supplying fluid to 2 small cylinders. cylinders extend and allow fingers to locate on a machine tool holder. When valve is off cylinder retracts and locks onto tool. These cylinders are tiny and require 1/2 as much pressure as the other 3 devices on the circuit. Well when this circuit is working the cylinders on device 2 are extending and we have heavy tools falling on the ground. We think it might be related to a drain issue. Thanks in advance..John http://i933.photobucket.com/albums/ad179/jnmaney/img788.jpg

Functional prototypes are a key step in product development â€“ they give engineers a chance to test new ideas and designs while also revealing how the product will stand up to real-world use. And when it comes to functional prototypes, 3D printing is rewriting the rules of whatâ€™s possible. Download Now
