The set screw and pushrod assembly in the Model 310/410 direct-acting solenoid valves has been redesigned to improve performance over the life of the valve. These two pieces were redesigned into a single threaded pushrod which eliminates the opportunity for wear between the two parts. After testing to 20 million cycles, the modification resulted in more consistent valve to valve performance, and valve performance that is more consistent with initial product performance. These valves are versatile, reliable, and compact 1/8-in. ported three-way and four-way direct acting solenoid valves designed to meet a variety of pneumatic applications.
