Product Highlights
SCF series prefilling valves are specially designed for fast cylinders. They are mainly used for large flow prefilling or draining of fast cylinder plugs to increase their idle stroke speed and return stroke speed.Compared with the traditional prefilling valve, the control piston is hydraulically controlled in both directions, with fast response speed, which can more effectively improve its fast down speed and return speed.The structure is compact, safe and reliable.

Notes：
1. Installation requirements: We recommend vertical installation.
2. Special requirements: If the user has special requirements for the valve's function, parameters, installation connection form and size, a special
order can be placed.
3. For fixing screws, we recommend using 10.9 grade high-strength standard screws.
