Product Description
The Control Valve Millivolt Type 438 TP is a gas control valve commonly used in gas heating systems that operate using millivolt technology. This type of valve is typically found in appliances such as gas heaters, gas fireplaces, and gas log fires. It plays a critical role in regulating the flow of gas to the burner based on the temperature set by the user, ensuring that the appliance operates efficiently and safely.
Key Features:
- Millivolt System: This valve operates using a millivolt system, which means it doesn't require an external power supply. It generates its own small electrical current from the thermocouple (a heat sensor) within the appliance. This eliminates the need for electrical wiring, making it ideal for gas appliances where electrical connections are minimal or unavailable.
- Thermocouple Integration: The millivolt system works in conjunction with a thermocouple, which senses the temperature and sends a millivolt current to the control valve. The valve then adjusts the gas flow accordingly, ensuring the appliance heats as desired.
- Pressure Regulation: The Control Valve Millivolt Type 438 TP is designed to regulate the gas pressure based on the needs of the appliance. This ensures that the right amount of gas is delivered to the burner, contributing to efficient combustion and heat generation.
- Durability: The valve is built to withstand the heat and pressures found in gas heating systems, providing long-lasting and reliable operation.
- Safety Features: The millivolt valve has built-in safety features, including a safety shut-off mechanism that prevents gas from flowing if there is no thermocouple signal, preventing the risk of gas leaks.
Applications:
- Gas Heating Systems: This type of control valve is often used in gas heaters, gas fireplaces, gas log fires, and other gas appliances that require millivolt-powered control systems.
- Millivolt Appliances: Commonly found in older model gas appliances or systems where no electrical power is available. It’s ideal for use in systems that rely on thermocouple-based controls.
- Residential & Commercial Use: Suitable for both residential and commercial applications, especially in situations where reliability and safety are crucial for gas-powered systems.
Benefits:
- No External Power Required: The millivolt system operates independently of external electrical power sources, making it perfect for appliances in locations where electricity may not be available.
- Safety: The integrated thermocouple and gas shut-off system enhance safety, ensuring that gas is only allowed to flow when the appliance is operating correctly, reducing the risk of leaks or fire hazards.
- Ease of Use: The Control Valve Millivolt Type 438 TP is designed to provide simple, straightforward control of gas flow based on temperature settings, ensuring ease of operation for the user.
- Energy Efficient: As the valve regulates the flow of gas efficiently, it ensures that the gas appliance operates optimally, reducing wastage and improving overall energy efficiency.
Summary:
The Control Valve Millivolt Type 438 TP is a vital component for millivolt-controlled gas appliances, providing safe, reliable, and efficient regulation of gas flow based on temperature control. Whether used in gas heaters, gas fireplaces, or other millivolt-operated appliances, this control valve ensures smooth operation by controlling gas pressure and flow, powered solely by a thermocouple.
