Bosch Rexroth R901049036 Hydraulic Control Valve

R901049036 is a Bosch Rexroth hydraulic control valve designed for proportional metering in railway maintenance machinery. The valve is associated with Plasser & Theurer part numbers HYA25-RPE2-325.DS0728 and Rexroth internal reference R900323180, signaling a cross-brand solution that blends Plasser's tamping technology with Rexroth’s hydraulic control platform. In distributor and tender listings, HYA25-RPE2-325.DS0728 is identified as a proportional valve used on Plasser tamping equipment, reinforcing its role in precision hydraulic control for track maintenance functions. The designation is widely referenced in procurement records as a component of railway hydraulic systems, confirming its specialized application in heavy-duty machine installations. While specific technical specifications such as flow or pressure ratings are not listed in these sources, the HYA25-RPE2-325.DS0728 label clearly ties this part to a family of proportional valves employed by Plasser and Rexroth for controlled actuation in rail-focused equipment. This valve is part of a Rexroth-Plasser collaboration intended for precise metering and actuation in railway maintenance tasks, commonly found in tamping and similar track-safety operations.
