Description

Delta DTV4896R Valve Control Temperature Controller

The Delta DTV4896R is a valve control temperature controller from Delta’s DTV Series, designed for industrial heating, cooling, and valve-position control applications.

It is suitable for systems that require accurate temperature monitoring and control using PID, ON/OFF, manual control, or programmable temperature control. The controller supports multiple input types, including thermocouples, RTD sensors, and analog signals, making it practical for machines, process systems, ovens, heating units, cooling systems, and industrial control panels.

The DTV4896R is commonly used where a temperature controller needs to control the opening and closing of a motorized valve through relay control, while also providing alarm functions and communication capability for monitoring through automation systems.

Delta’s DTV manual explains that the DTV valve-control function uses relay control outputs for forward/reverse motor operation to open and close the valve, and it can work with or without valve feedback signals.

Typical Applications

The Delta DTV4896R Temperature Controller is suitable for:

• Motorized valve temperature control
• Heating and cooling systems
• Hot water and steam control loops
• Industrial ovens and dryers
• Process temperature control
• Heat exchanger control
• HVAC temperature control panels

• Plastic and packaging machines
• Textile and industrial machinery
• Water treatment and utility systems
• PLC and SCADA monitored temperature systems

Why Use Delta DTV4896R?

The DTV4896R is a practical solution when the application requires temperature control with valve-position operation. Instead of using a basic ON/OFF temperature controller only, the DTV Series provides valve-control logic, PID control, alarm functions, and communication capability for industrial monitoring.

It is especially useful in control panels where temperature must be controlled through a motorized valve, heater, cooler, or process actuator, while allowing the system to be monitored by PLC, HMI, or SCADA through communication.
