Float Valve Assembly Replacement MP Industries 4059 White Brass Float

Description

Product Overview

The 4059 White Float Valve Assembly Replacement is engineered by MP Industries to deliver precise water level regulation in a variety of industrial and residential applications. Constructed from high‑grade brass for the shaft and reinforced plastic for the float, the unit combines corrosion resistance with mechanical strength, ensuring long‑term performance even in harsh environments. Its compact 1 × 1 × 1‑inch footprint allows easy installation in confined spaces, while the 0.38‑inch threaded inlet and outlet connections provide a secure, leak‑free seal on standard plumbing fittings. The white finish not only offers a clean aesthetic but also helps identify the component quickly during maintenance or inventory checks.

Designed as a direct replacement for the original MP Industries float valve, this assembly maintains the exact dimensions and mounting specifications of the OEM part, eliminating the need for adapters or modifications. The brass shaft delivers smooth vertical movement, reducing friction and wear, while the heavy‑duty plastic float offers buoyancy and durability across temperature fluctuations. With a weight of just 1.76 ounces, the valve is lightweight yet robust, making it suitable for both permanent installations and temporary setups in testing environments.

Usage

This float valve assembly is ideal for controlling water levels in swimming pools, water tanks, hydroponic systems, and industrial cooling reservoirs. Its reliable operation makes it a preferred choice for homeowners, pool service technicians, and facility managers who require consistent fill and drain cycles without manual intervention. The threaded 0.38‑inch inlet and outlet connections enable straightforward integration with existing pipework, whether the system uses PVC, copper, or galvanized steel. The valve’s design tolerates a wide range of pressures, ensuring stable performance from low‑flow residential setups to higher‑capacity commercial applications.

Installation is simple: attach the inlet thread to the water source, secure the outlet to the tank or pool, and adjust the float height to the desired water level. Once calibrated, the valve automatically opens to allow water in when the level drops and closes when the set point is reached, preventing overflow and conserving water. Its durability makes it suitable for seasonal use, with the ability to withstand repeated cycles without degradation, which is especially valuable in climates with large temperature swings.

FAQ

What types of fluids can this float valve control?

The valve is designed for water and water‑based solutions commonly found in pools, tanks, and cooling systems. It is not recommended for corrosive chemicals or solvents that could degrade the brass or plastic components.

Can the float height be adjusted after installation?

Yes, the float can be manually raised or lowered on the shaft to set the desired water level. Adjustments should be made while the system is off and the valve is empty to ensure accurate calibration.

Is this valve compatible with both PVC and metal piping?

Absolutely. The 0.38‑inch threaded connections are standard for PVC, copper, and galvanized steel fittings, allowing seamless integration across a wide range of pipe materials.

What is the warranty coverage for this product?

The 4059 Float Valve Assembly comes with a one‑year limited warranty covering manufacturing defects. Contact our support team with the purchase details for claim processing.

How do I maintain the valve to ensure optimal performance?

Periodic inspection of the brass shaft for wear and the plastic float for cracks is recommended. Clean any debris from the inlet and outlet threads, and verify that the float moves freely without obstruction.
