Specifications:
The document outlines the specifications for the 3-HPB 08 valve type with a pilot valve, designed for pressure regulation. The valve is externally controlled without a spring return and is available in different body materials such as galvanized steel and brass. The valve seat options include metal on metal and synthetic resin on metal, with seal materials available in NBR and FPM.

Pressure and Temperature Range:
The valve operates within a pressure range of 0-200 bar and an orifice size of DN 8 mm. It supports media temperatures from 0 to +60°C and ambient temperatures from 0 to +50°C.

Functionality:
The valve provides stepless pressure regulation with a maximum Kv value of 1.1 m³/h. It is suitable for gaseous and liquid media, including abrasive types. The flow direction is marked from P to R.

Electrical Specifications:
The valve can operate on 24V DC or 230V 50 Hz AC, with power consumption of 4.8 W for DC and 11.0 VA pick-up, 8.5 VA holding for AC. It features a protection rating of IP 65 and an energized duty rating of ED 100%.

Pneumatic Specifications:
The actuation pressure range is detailed in the actuation pressure-diagram, with air consumption adhering to DIN ISO 8573-1 standards. The control is preferably managed by a 3/2-way pilot valve during low-pressure circulation mode.

Additional Features:
Optional equipment includes an illuminated plug with varistor and M12x1 connector. The valve is explosion-proof with EEx m II T5 certification.

Diagrams:
The document includes actuation pressure diagrams for different pressure versions, illustrating the relationship between control pressure and media pressure, as well as flow rate and remaining pressure.
