BT2-2402 – 5/8″ Heater Water Valve Assembly, Pull-to-Open (4-Port)

Description

Overview

The BT2-2402 Water Valve Assembly is a pull-to-open heater control valve engineered for mobile and heavy-duty HVAC applications. When actuated by a control cable or linkage, the valve opens to allow coolant flow through the heater circuit. When released, the valve closes, restricting flow and reducing cab heat.

This mechanical design offers simple, reliable operation without electrical power, making it ideal for harsh environments and service-friendly installations.
