What is Temperature Control Valve (TCV)? Types and Applications

What is a Temperature Control Valve (TCV)?
The temperature control valve is one of the most commonly used valves. These valves control the temperature of fluids in various industrial applications. The efficient operation of this valve is critical for achieving maximum efficiency. This article primarily explains the operation, applications, and types of temperature control valves.

What is Temperature Control Valve?

A temperature control valve (TCV) regulates the flow or pressure of thermal fluid in a heating coil, tank shell, compressor, or other heating element to control the process temperature. Temperature control valves are also referred to as temperature regulators. TCVs are useful in industrial, marine, and process control applications where liquids must be diverted or mixed to achieve the optimal operating temperature. They can also be used in a cogeneration system to control the temperature of the heat recovery loop, allowing for maximum heat recovery and proper engine cooling. This contributes to providing the optimal temperature for your process while avoiding costly downtime. The number of their ports most commonly names valves for various applications. A two-way valve, for example, has two ports, as the name implies. Three ports are found on a three-way valve. A valve port is when fluids enter or exit the valve. Sometimes, TCV can be used to moderate engine temperatures, and a faulty TCV can even create the failure of car engines, as suggested by some car accident attorneys.

How Does a Temperature Control Valve Work?

Before delving into the workings of temperature control valves, it is vital to understand their design. The design of the temperature control valve consists of 4 major components parts: The temperature-sensing element sends a mechanical or electrical signal to an actuator. With this signal, the actuator then acts on a voltage supply that measures the position of the valve.

Types of Temperature Control Valves

Broadly there are Two Types of Temperature Control Valves

Thermostatic Control Valves

Valves that work by detecting and regulating the temperature of the liquid inside are called thermostatic control valves. This temperature control valve is self-contained and requires no external power supply. The chemistry of the wax material measures the operating temperature range and is preset at the factory or local dealer as recommended by the engine or equipment manufacturer. When the thermostatic element is adjusted according to the specific temperature, it can’t be reformed without installing a new element. This rugged yet simple design stops operators from accidentally overheating or overcooling equipment, resulting in poor fuel economy, costly repairs, and downtime.

Actuated Control Valves

Unlike internal sensing valves, actuation control valves are typically part of a complete system that uses an external probe to sense temperature changes. The probe transfers a signal to the powertrain control module (PCM) to open and close the valve port using an external power supply. Normal system types include pneumatic, electric, or a combination of both.

Temperature Control Valve Applications

The temperature control valves are most commonly used for industrial and residential applications. The following are the major applications of temperature control valves:
  • Small tanks
  • Acid baths
  • Unit heaters
  • Small jacketed pans
  • Small heater batteries
  • Tracer lines
  • Ironers
  • Small storage calorifiers

Some of the Industries that Use Temperature Control Valves are:

  • Food Industries
  • Oil and Gas sectors
  • Chemical and Petrochemical industries.
