Now there is a cylinder with a bore 180MM and a stroke type of100 mm. The direct solenoid valve drives too fast, and the effect of using the throttle valve is not ideal!

Cylinder diameter D= 180, stroke S= 100, reciprocating speed v= 100mm/2-5s can be adjusted. This is the most common and easy requirement for cylinder speed control. The correct way is to buy two 3/8-∮ 10 interface cylinder speed control valves (or one-way throttle speed control valves) directly connected to the cylinder, buy two 3/4 "-3/8" inner and outer lines (assuming that the cylinder interface should be 3/4 "), and put two 3/8". Domestic products can be easily done for tens of yuan (of course, imported products are ideal), ensuring that you can adjust the speed range of the whole journey 1-6 seconds at will.

It should be noted that the hydraulic cylinder can generally control the oil intake by adjusting the throttle valve (how much oil will not expand and how many roads the oil will take), while the cylinder is different and cannot be adjusted by the intake throttle valve (gas will expand greatly when entering). The speed of the cylinder can not be controlled ideally, so it must be unrestricted when entering. However, the other cavity (gas to be exhausted) of the cylinder is controlled to throttle, forming back pressure damping in the cavity and stabilizing the propulsion force of the cylinder. It will not throttle when switching to air intake, but it will throttle when it is exhausted by another chamber. This is the speed regulating valve composed of one-way valve and throttle valve mentioned above. Remember! Adjust the speed there to adjust the throttle at the exhaust end, and the intake end is not adjustable, and vice versa.
