Features
- When the lowering speed exceeds preset value, as it might happen in case of hose failure, the flow is blocked.
- These valves should ideally be screwed directly into the actuator outlet port. Sealing parts are superfinished and enable to lock the load in the position where the actuator is in the moment of hose failure.
- These valves can be supplied, on request, allowing an emergency lowering of the load. It is recommended to fit a flow regulator valve downstream the hose burst valve, at the end of the flexible hose, to control the lowering speed at the nominal value.
- The “S” gap must be adjusted to allow a flow at least 50% over the nominal regulated flow from the actuator.
