Festo Pneumatic Manual Control Valve HE-3-QS Series Maximum Operating Pressure 10 bar 0°C to 60°C HE-3-QS-12

Festo HE-3-QS-12 Pneumatic Manual Control Valve is designed for manual actuation in compressed air systems used in industrial automation. It features a three-way, manually operated shut-off mechanism allowing bistable switching of flow direction, providing precise control over pneumatic actuators or circuits within standard industrial temperature ranges from 0°C to 60°C.

This valve can handle operating pressures from -0.95 bar up to 10 bar, making it suitable for a broad range of industrial pneumatic applications. The valve body is constructed from reinforced polybutylene terephthalate combined with aluminium and brass components, ensuring robustness and longevity under industrial conditions.

The valve inlet and outlet ports are configured with male/female connections, offering versatility for installation. It utilizes soft sealing to reduce leakage and ensure smooth and reliable switching action. Direct pilot control allows immediate manual response, while its in-line design with a through-hole facilitates integration into panels or pipelines securely.

Mounting of the valve is flexible as it may be positioned in any orientation, making it suitable for diverse assembly line setups and workshop environments. The valve is specified for use with compressed air complying with ISO 8573-1 standards and supports lubricated operation when necessary.

Common uses include manual isolation of pneumatic actuators, switching pilot lines in pneumatic control panels, diverting compressed air between workstations, and manually testing pneumatic sensors and valves. Although it controls flow direction manually, it does not incorporate dedicated exhaust flow control features, operating without exhaust modulation.

Operates over a pressure range from -0.95 bar to 10 bar. Constructed with reinforced polybutylene terephthalate, aluminium, and brass for durability. Inlet and outlet male/female port configuration for versatile installation.
