Description
Overview:
The Valve Kit for Nilfisk C105, C110 and C120 pressure washers is a genuine replacement set that restores smooth water control inside the pump. Supplied as an official Nilfisk component (OEM No. 31000518), it is built to the original specification for reliable sealing and flow regulation. The kit uses corrosion‐resistant stainless steel springs with durable engineered polymer valve components to withstand regular use and water exposure. It is designed for compact and mid‐range Nilfisk machines used at home or on site, including models such as the C110.4-5 PCD X-TRA and CORE 140-6 POWERCONTROL. Fitting this kit as part of routine servicing helps recover stable pressure, reduce pulsing, and extend pump life in domestic and light trade pressure washers.
Key Features:
- Genuine Nilfisk spare (OEM 31000518) for assured compatibility and performance
- Durable build: stainless steel springs and robust polymer valve bodies for long service life
- Restores correct water flow and pressure stability; helps reduce pulsing and uneven output
- Aids recovery from wear, limescale, or debris-related valve damage
- Straightforward to fit with basic hand tools, minimising downtime
- Broad model coverage across Nilfisk C‐Series and CORE ranges
- Supports preventative maintenance to protect the pump and reduce repair costs
- Factory‐spec components for consistent sealing and reliable operation
Typical Applications:
Used during pump overhauls and routine services on Nilfisk pressure washers that clean patios, vehicles, tools, façades, and job sites. Ideal when symptoms include low or fluctuating pressure, hard starting under load, or bypassing caused by worn valves. Suitable for homeowners, tradespeople, and hire or fleet maintenance.
