This Poppet Check Valve is a one-way valve device that allows flow in one direction while preventing flow in the reverse direction. It is typically used for controlling the direction of fluids and is designed with an opening for pressure relief. Its lightweight, compact design makes it easy to install and maintain.

Material
| Cartridge | 0.29 kg(0.63 lbs);Steel with hardened work surfaces. Zinc-plated exposed surfaces.Seal: O-rings and back-up rings. |
| Standard Ported Body | Weight: 0.57 kg. (1.25 lbs.); Anodized highstrength 6061T6 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. Industry common cavity. |
The ICV16-20 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 to ②.
