The Festo H Series Check Valve comes in various configurations, including push-in connectors, threaded connections, and combinations of both. The series offers valves with non-return functions, suitable for different flow rates ranging from 115 to 5900 l/min, depending on the specific model.
The H series includes models with push-in connectors (QS-4 to QS-12) and threaded connections (M5 to G3/4). The HA and HB series feature combinations of male threads and push-in connectors, allowing for versatile installation options.
There are three variations in the H series:
H Series:
- Offers both push-in connector and threaded connection options
- Available in single connection types (e.g., QS-4 to QS-4, or G1/4 to G1/4)
- Includes a wider range of sizes, from very small (M5) to larger (G3/4)
- Generally has higher flow rates, especially in larger sizes
HA Series:
- Combines male threaded connections with push-in connectors
- Flow direction is from the male thread to the push-in connector
- Designed for applications where a threaded input and push-in output are needed
- Available in sizes from M5 to R1/2 for the threaded side, and QS-4 to QS-12 for the push-in side
HB Series:
- Also combines push-in connectors with male threaded connections
- Flow direction is opposite to HA series: from the push-in connector to the male thread
- Designed for applications where a push-in input and threaded output are required
- Available in the same size range as the HA series
