Characteristics
| VALSTOP-EUROSTOP CHECK VALVES | All technical data about VALSTOP check valves (heavy line) are valid for EUROSTOP check valves (standard line) too, except for the pressure/temperature diagram concerning the VALSTOP series. |
| END CONNECTIONS | Ends are ISO 228/1 threaded. |
| USES (for VALSTOP items H0151- H0153) |
For any type of hydraulic, heating or pneumatic system. For hot and cold water, compressed air, oils. |

| INSTALLATION | This valve can be installed in any position (horizontal, vertical, oblique). |
| WORKING PRESSURE | Min 0,05 bar with water. Max from PN 40 (1/4”) up to PN 10 (3”). See pressure/temperature diagram. |
| MINIMUM OPENING PRESSURE | Min 0,025 bar (25 cm water column). |
| MINIMUM TIGHTNESS PRESSURE | Min 0,05 bar (50 cm water column). |
| TEMPERATURE LIMITS | Art. H0141 with fluoroelastomer gasket From -15°C to +130°C. Art. H0151/H0161 with NBR gasket From -20°C to +100°C. See pressure/temperature diagram. |
