. This is especially important when working with cyanoacrylates . 7. Is It Difficult to Produce Consistent Shots? If your valves are taking too long to set up and you cannot obtain consistent results, a valve system with a dedicated controller is a more efficient approach to establish shot size and regulate valve operation
