A screw-in, cartridge-style, hydraulic check valve for use as a blocking or load-holding device.
The Poppet Check Valve is a type of hydraulic check valve that is designed to be screwed into a hydraulic system as a cartridge-style component. It is commonly used as a blocking or load-holding device in hydraulic systems to prevent reverse flow or maintain pressure in a specific direction.

Material
| Cartridge | Weight: 0.16 kg. (0.35 lbs.); Steel with hardened work surfaces. Zinc-plated exposed surfaces. |
| Seal | D type seal ring. |
| Standard Ported Body | Weight: 0.57 kg. (1.25 lbs.); Anodized highstrength 6061 T6 aluminum alloy, rated to 240 bar (3500 psi). |
Ductile iron and steel bodies available; dimensions may differ. Consult Inno.
| 1. Hardened seat for long life and low leakage. | |
| 2. Optional bias springs for back-pressure application flexibility. | |
| 3. Fully guided check assembly. | |
| 4. Cost-effective cavity. |
The ICV12-20 allows 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 to②.
