Water Tank Valve | WP1540, WP1550

The Wacker Neuson is a genuine OEM Shutoff Valve designed for the WP1540 and WP1550 series single-direction vibratory plate compactors. Sourced directly from Wacker Neuson, this part carries the same specifications as the original component installed at the factory, ensuring a verified, drop-in fit across the full WP1540 and WP1550 model range — including AW, A, V, R, and W variants. Whether you're servicing a standard WP1550 or a wheel-kit-equipped WP1540AW, part number is the correct replacement. Keeping this valve in proper working condition is essential to maintaining reliable fuel or fluid control and protecting the machine during storage and transport.

Key Features

• Genuine OEM Construction — Manufactured to Wacker Neuson's original material and dimensional specifications, ensuring the valve seats, seals, and actuates exactly as the original did.
• Direct Swap Installation — Matches the original mounting configuration and port sizing on the WP1540 and WP1550 platforms, so disassembly and reinstallation follow the standard service procedure with no adaptation.
• Broad WP-Series Fitment — Confirmed fitment across WP1540 and WP1550 variants including AW, A, VW, V, RW, R, W, and wheel-kit-equipped models, covering a wide production run of 15 kN vibratory plates.
• Maintains Positive Fluid Shutoff — A functioning shutoff valve gives the operator clean, reliable control over fuel or fluid flow; a worn or leaking valve risks uncontrolled seepage, difficult starting, and potential fire hazard.
• Fuel System Safety — As a fuel-circuit component, using the correct OEM valve maintains proper shutoff integrity and helps prevent fuel leaks during transport, storage, or service intervals.

A shutoff valve controls the flow of fuel from the tank to the engine's fuel system. On vibratory plate compactors like the WP1540 and WP1550, closing the valve during storage or transport prevents fuel from reaching the carburetor, reducing the risk of flooding, leaks, or stale-fuel buildup in the fuel circuit. When the valve deteriorates — through cracking, sticking, or a failed internal seal — it can either restrict fuel delivery and cause hard starts or fail to close fully and allow unintended fuel flow. Replacing a faulty shutoff valve promptly restores proper fuel management and keeps the compactor ready for the next job.
