The ST307V2350B accessory belongs to the Vickers Hydraulic Accessories series and is produced by Vickers to regulate pressure in automated fluid circuits. It features a knurled handknob (V2) that allows tool-free setpoint adjustment. The component mates to pipework through a G 1/4 BSPF port to fit common manifolds. It supports settings from 20 bar to 350 bar so medium-pressure loops can be tuned accurately. Oils with viscosities between 10 and 800 mm²/s move through the device without loss of function. Ambient operation from −40 °C to 90 °C covers cold starts and elevated machine temperatures. The unit weighs 0.5 kg, which aids direct mounting on compact valve stacks.
The housing tolerates a maximum internal pressure of 600 bar for over-pressure resilience. Control wiring attaches through an EN 175301-803 Type A connector, giving a standardized interface to PLC I/O. An IP65 ingress rating keeps dust and low-pressure water out of the enclosure. The contact set carries inductive loads up to 4 A at 24 V DC and 1 A at 250 V AC, allowing direct connection of solenoid coils. Resistive loads may draw up to 5 A on 24 V DC or 250 V AC lines, supporting lamps or relay coils without auxiliary relays. These electrical limits define safe current ranges and maintain reliable switching inside hydraulic automation panels.
