Float Valve Fixes! Expert Tips for Robert Valves Revealed

Mastering Robert Manufacturing Float Valve Repairs: A Comprehensive Guide

This article aims to provide you with practical and helpful information for diagnosing and fixing common issues related to Robert Manufacturing float valves. We’ll break down the process into easy-to-understand steps, covering common problems and offering expert tips.

Understanding Robert Manufacturing Float Valves

Before diving into fixes, it’s important to have a basic understanding of what these valves do and how they function.

• Functionality: Robert Manufacturing float valves are designed to automatically control liquid levels in tanks and containers. They typically consist of a valve body, a float, and a connecting arm.
• Mechanism: As the liquid level rises, the float rises with it. This movement causes the arm to gradually close the valve, restricting the flow of liquid. When the liquid level drops, the float drops, opening the valve and allowing more liquid to enter.
• Common Applications: You’ll find these valves in various applications, including:
  • Water tanks
  • Livestock watering systems
  • Industrial process tanks
  • Evaporative coolers (swamp coolers)

Diagnosing Common Robert Manufacturing Float Valve Problems

Identifying the root cause of a float valve issue is crucial for effective repair. Here’s a breakdown of common problems and how to spot them.

Leaking Valve

A leaking valve is perhaps the most frequent issue.

• Symptoms: Water or liquid constantly dripping from the valve, even when the tank should be full.
• Possible Causes:
  • Worn or Damaged Valve Seat: This is the most likely culprit. Over time, the valve seat can become worn, cracked, or corroded, preventing a tight seal.
  • Debris Obstruction: Small particles of dirt or debris can lodge between the valve seat and the valve itself.
  • Corroded Valve: Rust or corrosion can prevent the valve from seating properly.
  • Improper Float Adjustment: If the float arm is bent or misadjusted, it may not be applying enough pressure to fully close the valve.

Valve Not Shutting Off Completely

This results in the tank overflowing.

• Symptoms: The tank continuously overflows, even after reaching the desired liquid level.
• Possible Causes:
  • Float Interference: Check for obstructions that might prevent the float from rising freely.
  • Float Punctured or Leaking: A float filled with liquid will be heavier and less buoyant, resulting in improper valve closure.
  • Improper Float Adjustment: Similar to a leaking valve, incorrect float adjustment can prevent proper closure.
  • Valve Seat Damage: Debris or damage may keep the valve from sealing completely

Valve Not Opening

Leading to an empty or low tank.

• Symptoms: The tank remains empty or at a low level, even though the valve should be open.
• Possible Causes:
  • Float Interference: The float might be stuck in the down position, preventing the valve from opening.
  • Frozen Valve: In cold climates, the valve can freeze, preventing it from operating.
  • Stuck Valve Stem: The valve stem may be stuck due to corrosion or mineral buildup.

Expert Tips for Robert Manufacturing Float Valve Repairs

Now, let’s explore some practical tips for fixing these common float valve problems.

Assessing the Valve Seat

The valve seat is critical for a good seal.

1. Visual Inspection: Carefully inspect the valve seat for signs of wear, cracks, corrosion, or debris. A magnifying glass can be helpful.
2. Cleaning the Valve Seat: Use a soft cloth or brush to remove any debris from the valve seat. A mild abrasive cleaner can be used cautiously to remove light corrosion.
3. Replacing the Valve Seat: If the valve seat is severely damaged, it will need to be replaced. Robert Manufacturing usually sells replacement valve seats separately. Refer to your valve model documentation for the correct replacement part.

Checking and Adjusting the Float

Proper float function is essential.

1. Inspect the Float: Examine the float for any signs of punctures, cracks, or leaks. If the float is damaged, replace it.
2. Test the Float: If you suspect a leak, remove the float and shake it. If you hear water sloshing inside, it’s punctured and needs to be replaced.
3. Adjust the Float Arm: Carefully bend the float arm to adjust the liquid level. Lowering the float arm will lower the liquid level, while raising it will increase the level. Small adjustments can make a big difference.

Dealing with Corrosion and Debris

Contamination can cause many issues.

1. Cleaning the Valve: Disassemble the valve and clean all parts thoroughly with a brush and mild detergent.
2. Removing Corrosion: Use a wire brush or sandpaper to remove any rust or corrosion from the valve body and stem. Be careful not to damage any sealing surfaces.
3. Flushing the System: After cleaning or repairing the valve, flush the supply line to remove any debris that might be present.

General Maintenance

Preventative care goes a long way.

• Regular Inspections: Inspect your Robert Manufacturing float valves regularly for signs of wear, corrosion, or leaks.
• Filter Installation: Install a filter in the supply line to prevent debris from entering the valve.
• Proper Winterization: In cold climates, protect the valve from freezing by insulating it or draining the system during the winter months.

Tools You Might Need

Having the right tools on hand makes the repair process easier.

• Wrenches: For disconnecting and assembling the valve. Select appropriate sizes for your valve’s fittings.
• Screwdrivers: For removing screws or adjusting the float arm.
• Pliers: For gripping and bending the float arm.
• Adjustable Wrench: Useful for various sized connections.
• Wire Brush: For removing corrosion.
• Sandpaper: For smoothing rough surfaces.
• Replacement Parts: Valve seats, floats, and O-rings. Consult your valve’s documentation for correct part numbers.

By following these guidelines and expert tips, you can effectively diagnose and repair common issues with Robert Manufacturing float valves, ensuring their reliable operation for years to come. Remember to always consult the manufacturer’s documentation for your specific valve model before attempting any repairs.

Hopefully, these tips have given you a solid foundation for tackling issues with your robert manufacturing float valves. Don’t hesitate to dive deeper and keep experimenting – the best way to learn is by doing! Good luck with your repairs!
