Cat Pumps Brass Thermal Valve 180 degrees 3/8"

Automatic Thermal Relief for High-Pressure Pump Protection

Cat Pumps Brass Thermal Valve – 3/8" 180°F offers a reliable solution to protect pressure washer systems from overheating. This durable valve automatically opens at 180°F, releasing hot water and allowing cooler water to enter—preventing pump damage during bypass mode or extended idle periods.

🔧 Features

• — Durable brass body resists corrosion and thermal stress
• — Automatically opens at 180°F to release overheated water
• — 3/8" NPT connection for easy system integration
• — Compact design fits tight installations

✅ Advantages

• — Prevents pump damage caused by heat buildup
• — Improves equipment lifespan and efficiency
• — Ensures consistent thermal protection during bypass
• — Compatible with most high-pressure washer systems

🎯 Benefits

• — Protects your investment from costly thermal wear
• — Reduces maintenance downtime
• — Reliable relief response at a fixed 180°F threshold
• — Rugged performance in demanding environments

🛠 How to Use

Install the thermal valve on the pump outlet or bypass line. When water temperature reaches 180°F, the valve opens to release water and closes as cooler water flows in. Monitor periodically for buildup or wear.

📅 When to Use

Use on pressure washer systems during extended idle times, closed bypass operation, or in hot environments where overheating is a risk.

Protect your pump with automatic heat relief—depend on Cat Pumps thermal valve performance.
