How does the Mini ball valve with hose plug connection, plastic, type HVFF ensure safe venting when installed incorrectly?

The Mini ball valve with hose plug connection, plastic, type HVFF ensures safe venting even if installed incorrectly by being a three-way sliding valve (3/2) with a dedicated vent path. Although it must be installed per the flow direction marked on the body, its internal design routes the downstream volume to vent openings at the top of the knob when the valve is closed or power is cut. Those top-located vents bleed pressure from the downstream side, allowing safe depressurization for repairs and maintenance. Materials (plastic body, brass slider, NBR O-rings) and the knob-mounted venting ports ensure reliable venting within the specified 0Â°C to +60Â°C operating range.

How should I orient the Mini ball valve with hose plug connection, plastic, type HVFF to guarantee correct venting on power loss?

To guarantee correct venting on power loss, install the Mini ball valve with hose plug connection, plastic, type HVFF in the exact orientation shown by the flow direction arrow stamped on the valve body. The valve is a miniature 3/2 sliding valve with venting: when oriented correctly, the downstream side will be connected to the top-knob vent ports when power is cut, allowing the downstream circuit to exhaust through the openings in the top of the knob. Incorrect orientation (reversing inlet and outlet) can prevent the downstream circuit from venting properly. Practical steps: - Identify the flow direction arrow on the valve body. - Connect the supply hose to the inlet side indicated by the arrow and the downstream hose to the outlet side. - Mount the valve so the knob and its top vent openings remain accessible and upright; the vent openings must not be blocked by mounting surfaces or fittings. - Verify operation by energizing the system, then cutting power and confirming that the downstream line vents through the knob openings. Follow the specified operating conditions (0Â°C to +60Â°C) and use hoses with the calibrated outer diameters for the plug connections to ensure reliable sealing and correct venting.

Additional information

Material	P – material (plastic)

Miniature valve designed for pneumatic installations, with plug connections for direct mounting on hoses with calibrated outer diameters. Functionally similar to a ball valve (flow closure by rotating the knob 90º), it is, however, a miniature three-way sliding valve (3/2) with venting – it must be installed according to the flow direction indicated on the body. When the power supply is cut off, the system downstream of the valve is vented through openings located at the top of the knob, allowing for repairs and maintenance of the system. Body material: plastic. Slider material: brass. Seals: NBR o-ring. Operating temperature: from 0°C to +60°C.
