It is a compact and multifunctional directional control valve that merges the characteristics of a ball valve and a check valve. This valve is specifically engineered to provide versatility in fluid control applications while ensuring efficient prevention of backflow. Its compact design makes it particularly suitable for systems with space limitations, without compromising on performance or functionality.

Material
| Cartridge | Weight: 0.05 kg. (0.12 lbs.); Steel with hardened work surfaces. Zinc-plated exposed surfaces. |
| Seal | Buna-N O-rings and back-up rings (standard). |
| 1. Hardened seat for long life and low leakage. |
| 2. Optional bias springs for back-pressure application flexibility. |
| 3. Fully guided check assembly. |
| 4. Miniature size. |
| 5. Fast closing and seating. |
The ICV04-20 and ICV04-B20 allow flow passage from ① to ②, while normally blocking oil flow in the opposite direction. The cartridge has a fully guided check which is spring-biased closed until sufficient pressure is applied at ① to open ②.
