| Standard Ported Body | Weight: 0.16 kg. (0.35 lbs.); Anodized high-strength 6061 T6 aluminum alloy, rated to 240 bar (3500 psi). Ductile iron and steel bodies available; dimensions may differ. Consult Inno. |
| Standard Coil | Weight: 0.27 kg. (0.60 lbs.); Unitized thermoplastic encapsulated, Class H high temperature magnetwire. |
| E-Coil | Weight: 0.41 kg. (0.90 lbs.); Perfect wound,fully encapsulated with rugged external metal shell; Rated up to IP69K with integral connectors. |
| 1. Continuous-duty rated coil. |
| 2. Optional coil voltages and terminations. |
| 3. Cartridges are voltage interchangeable. |
| 4. Hardened seat for long life and low leakage. |
| 5. Optional waterproof E-Coils rated up to IP69K. |
| 6. Manual override option. |
| 7. Industry common cavity. |
When de-energized, the ISV10-28 blocks flow in both directions. When energized, the cartridge's poppet opens on its seat, allowing flow from ② to ① or from ① to ②.
