Tecomec VRT3 Unloader Valve with Gauge Connection

The Tecomec VRT3 unloader valve with gauge port is a professional pressure regulating valve designed for high-pressure cleaning systems that require accurate pressure monitoring.

The integrated manometer connection allows installation of a pressure gauge directly on the valve, enabling precise pressure adjustment and safer machine operation.
When the spray gun is released, the valve diverts water to bypass, protecting the pump from overload and extending equipment lifespan.

Ideal for industrial and continuous-duty pressure washers.

Main Features

• Built-in pressure gauge connection

• Adjustable pressure control

• Stable operating pressure

• Protects pump seals and pistons

• Prevents pressure spikes

• Heavy-duty brass construction

• Suitable for hot water machines

• Designed for professional use

Technical Specifications

How It Works

During operation the valve regulates pressure.
When the trigger gun closes:

1. Water is redirected to bypass

2. Pump pressure drops safely

3. Equipment is protected from overload

The gauge connection allows real-time monitoring for precise adjustment.

Applications

• Industrial pressure washers

• Car wash installations

• Heavy equipment cleaning

• Hot water cleaning machines

• Continuous operation systems

Why Choose VRT3 with Gauge Port

This version is ideal when accurate pressure setting is required.
It improves safety, reduces maintenance, and ensures correct operating pressure for sensitive cleaning tasks.

How to Choose the Correct Unloader Valve

Choosing the correct unloader valve is critical for pressure washer performance and pump life.
The valve must match both pressure (bar) and water flow (L/min). Installing an incorrect regulator can cause overheating, seal damage, or unstable pressure.

For professional machines always verify:

• Maximum pressure rating (bar / PSI)

• Flow rate capacity (L/min / GPM)

• Inlet and outlet connection size

• Presence of bypass or total-stop system

• Hot water compatibility

If the valve capacity is too small, pressure spikes occur.
If the valve is too large, pressure becomes unstable.

What Happens Without a Proper Pressure Regulator

A pressure washer pump depends on the unloader valve to release pressure when the trigger gun closes.

Without a correct valve the machine may suffer:

• Pump head cracking

• Piston seal wear

• Motor overload

• Frequent thermal cut-off

• Hose vibration and leaks

That is why every professional pressure washer system requires a calibrated pressure regulator.
