REXROTH 3712090050 Pneumatic Solenoid Valve

OverviewREXROTH 3712090050 is a compact pneumatic solenoid valve manufactured by Bosch Rexroth, made in Germany, widely used for directional control of compressed air in marine and industrial automation systems. This valve belongs to the classic Rexroth pneumatic control valve series, designed to switch air flow direction to drive pneumatic cylinders, actuators and air-operated auxiliary mechanisms. It adopts a robust cast aluminum housing, suitable for continuous operation under vibration, humidity and salt spray conditions. This part is mostly obsolete and mainly supplied as maintenance spare parts for legacy ship and factory pneumatic control cabinets. In marine engine control, deck machinery, process plant pneumatic interlock and old automation retrofit projects, REXROTH 3712090050 delivers stable air directional switching and is a common pneumatic valve spare.

FeaturesREXROTH 3712090050 has a compact block structure with standard sub-base mounting interface. The Pneumatic Solenoid Valve provides reliable air direction switching with low internal leakage and fast response. It is built with corrosion-resistant coating and complies with marine environmental requirements for shock and vibration. The valve body integrates solenoid coil and valve spool assembly, easy to inspect and replace on site. It supports standard industrial compressed air medium with filtration and lubrication as required. It meets industrial EMC standards and can work stably in heavy-duty workshop and shipboard environments. REXROTH 3712090050 can be combined with other pneumatic valves and logic components to build pneumatic control circuits.

SpecsREXROTH 3712090050 pneumatic directional solenoid valve. The Pneumatic Solenoid Valve material number: 3712090050. Medium: filtered compressed air. Construction: aluminum alloy valve body. Mounting: sub-base mounted. Origin: Germany. Weight: approx 480 g. Application: marine, industrial pneumatic control. Lifecycle: discontinued. It is stocked as pneumatic directional control spare.

Operating ParametersREXROTH 3712090050 ambient operating temperature: -20℃ ~ +60℃. The Pneumatic Solenoid Valve relative humidity: 5%~95% non-condensing. Working medium: compressed air. Pressure range: standard pneumatic working pressure. EMC: comply with industrial and marine IEC requirements.

PrincipleREXROTH 3712090050 receives electrical signal to energize the built-in solenoid coil. The Pneumatic Solenoid Valve pushes the internal spool to shift position, changing the flow path of compressed air between inlet and outlet ports. When the coil is de-energized, the spool resets to original position by spring force and switches air circuit again. Long-term moisture contamination, air impurity or coil burnout will cause REXROTH 3712090050 spool sticking or failure to switch.

ApplicationsREXROTH 3712090050 is widely deployed in ship engine control systems, deck machinery, cargo handling equipment, process industry pneumatic interlock and old factory automation lines. The Pneumatic Solenoid Valve undertakes air direction switching for pneumatic actuators, air cylinders and pneumatic control relays. It cooperates with air filter regulator, limit switches and control panels to form pneumatic control loops. REXROTH 3712090050 is a preferred spare for legacy Rexroth pneumatic control system maintenance.
