48R454 - Walter 48-R 454 Replacement Umbrella Check Valve

Restore Your Sprayer's Performance

The Walter 48R454 Umbrella Valve is an essential replacement component designed specifically for Walter Surface Technologies' line of industrial sprayers and dispensing systems. Over time, the internal valves of pump mechanisms can wear down due to repetitive use and exposure to industrial chemicals. This genuine OEM umbrella valve is engineered to exact specifications, ensuring a perfect fit and reliable function within your existing equipment.

Functioning primarily as a check valve, this component is responsible for allowing fluid or air to flow in one direction while preventing backflow. This is critical for maintaining the necessary pressure within the sprayer bottle or system to ensure a consistent and even spray pattern. If your sprayer is losing pressure, sputtering, or failing to dispense fluid effectively, a worn umbrella valve is often the culprit.

Manufactured from high-quality, chemical-resistant elastomeric materials, the 48R454 is built to withstand the harsh environments often associated with welding and metalworking cleaning agents. Whether you are using Walter's anti-spatter solutions, cleaners, or degreasers, this valve ensures your application tools remain operational. Keeping a spare umbrella valve on hand is a smart maintenance strategy to minimize downtime in your production line.
