Red Dot RD-5-7760-1P Push-Open Water Valve | 72R5220 Cable Heater Valve

Description

Overview

The Red Dot RD-5-7760-1P is a mechanical water valve designed for mobile HVAC heater applications. It opens when the control cable is pushed forward, allowing coolant to flow into the heater core. This simple but effective control method delivers dependable temperature regulation in demanding environments.

How This Valve Works

This valve uses a push-operated cable mechanism located on the inlet side. When the cable moves forward, the valve opens. When the cable retracts, the valve closes. Because it relies on a mechanical cable rather than electronic control, it remains reliable in harsh conditions such as vibration, extreme temperatures, and off-road operation.

The heavy-duty metal housing provides long service life and resists corrosion. As a result, this valve is widely used in trucks, buses, agricultural machinery, and construction equipment.
