Brass Adjustable Float Valve with Stainless Steel Ball

Brass adjustable float valve with stainless steel ball for automatic water level control in water tanks and compatible water systems. Available in 1/2″–2″ sizes, with a working pressure range of 0.04–0.6 MPa and a working temperature range of 0°C to 60°C.

This brass adjustable float valve with stainless steel ball is designed for automatic water level control in tanks and water storage systems.

As the water level rises or falls, the stainless steel float ball moves the operating rod and valve mechanism to control the incoming water supply automatically without electrical power.

The current factory specification covers sizes from 1/2″ to 2″, with a working pressure range of 0.04 MPa to 0.6 MPa and a working temperature range from 0°C to 60°C.

3. How Does an Adjustable Float Valve Work?

The float valve uses the water level inside a tank to control the inlet mechanically.

Water Level Drops

As the water level falls, the stainless steel float ball moves downward with the water surface.

Valve Opens

Movement of the float arm operates the valve mechanism and allows water to enter the tank.

Water Level Rises

As the tank fills, the stainless steel ball rises with the water level.

Valve Closes

When the float reaches the set position, the mechanism closes the inlet to help maintain the required water level.

The valve operates mechanically and does not require an electrical level sensor or power supply for normal operation.

4. Adjustable Float Arm Design

The float ball is connected to the valve body through an extended operating arm.

This arrangement allows the movement of the water level to operate the inlet valve mechanically.

For replacement or OEM projects, the rod length, float position and required shut-off water level should be confirmed according to the tank dimensions and installation arrangement.

The currently available technical information does not specify the standard rod length or adjustment range. If these dimensions are important, confirm them before ordering.

5. Stainless Steel Float Ball

This model uses a stainless steel float ball to follow changes in the water level.

The float ball provides the buoyancy required to move the operating mechanism as the tank fills or empties.

The current technical information does not specify the stainless steel grade or float-ball diameter.

If your project requires a particular stainless steel grade, float diameter or dimensional specification, include this information in your RFQ.

6. Working Pressure Range: 0.04–0.6 MPa

The current factory specification defines a working pressure range of:

0.04 MPa ≤ PW ≤ 0.6 MPa

This should be understood as a working pressure range, rather than simply describing the valve as a 0.6 MPa pressure-rated product.

Selection Tip:
Actual inlet pressure should remain within the specified operating range. If the system pressure falls below or exceeds the listed range, product suitability should be evaluated before ordering.

7. Available Sizes

The current factory information confirms the following valve sizes:

Nominal Size Working Medium Working Pressure
1/2″ Water 0.04–0.6 MPa
3/4″ Water 0.04–0.6 MPa
1″ Water 0.04–0.6 MPa
1-1/4″ Water 0.04–0.6 MPa
1-1/2″ Water 0.04–0.6 MPa
2″ Water 0.04–0.6 MPa

8. Working Temperature

The specified working temperature range for this float valve is:

0°C to 60°C

Application conditions outside this temperature range should be evaluated separately before product selection.

9. Typical Water Level Control Applications

Adjustable float valves are used where the incoming water supply needs to be controlled automatically according to the level inside a tank or reservoir.

01
Water Tanks
02
Storage Tanks
03
Water Reservoirs
04
Water Supply Systems

Final suitability depends on the tank arrangement, inlet pressure, required water level, temperature, connection specification and material requirements.

10. What Should Buyers Confirm Before Ordering?

Float valves should not be selected only by nominal inlet size.
The complete tank and operating conditions should also be considered.

Before requesting a quotation, confirm:

  • Required valve size
  • Thread or connection standard
  • Actual inlet pressure
  • Working temperature
  • Tank dimensions
  • Required water shut-off level
  • Rod length requirement
  • Float ball dimensions if specified
  • Required brass material if applicable
  • Required stainless steel grade if applicable
  • Order quantity
  • Logo and packaging requirements

11. Replacement and OEM Float Valve Projects

When replacing an existing float valve, a physical sample or complete dimensions can help confirm whether the new valve will match the existing tank installation.

Useful information includes:

  • Existing valve photos
  • Connection size
  • Thread standard
  • Rod length
  • Float ball diameter
  • Tank installation dimensions
  • Working pressure
