Valves are critical components when it comes to plumbing and HVAC systems. They’re responsible for controlling the flow of water, gas, and other fluids. Among the different types of valves, the service valve and king valve may sound similar, but they’re distinct. If you’re installing or repairing a plumbing or HVAC system, understanding the differences between service and king valves will help you make the right call.
What is Service Valve?
A service valve is a shutoff valve that controls fluid flow in a pipe connected to an appliance. Commonly found in refrigerant and HVAC systems, service valves are necessary for maintenance or repair work. They’re designed to be easily accessible and operate, even for non-experts. Service valves are usually mounted on the line or close to the equipment, making them more visible and easier to use.
What is a King valve?
King valves are another type of valve used in plumbing and HVAC. They’re also a type of shutoff valve, but they’re mainly used for controlling water flow. They’re typically installed near the main water meter and are the primary shutoff point for the water supply. Because of their placement, they’re less visible and might be more challenging to operate for inexperienced individuals.
Differences Between Service Valve and King Valve
The most apparent difference between the service and king valves is what they control. Service valves regulate the flow of refrigerant, gas, or other fluids entering or leaving an appliance. King valves, on the other hand, hold the flow and volume of water in a building’s plumbing system.
In terms of operation, service valves are designed to be easy for anyone, while king valves require special tools to turn the valve stem. Due to the high rate of use and wear, king valves are made of durable and robust materials (e.g., brass), while service valves are made of steel or other materials.
Uses of service valve and king valve?
Service valves and king valves have different applications in plumbing and HVAC systems. Service valves are most commonly found in refrigerant and HVAC systems, where they regulate the flow of gases and are necessary for maintenance and repairs. They’re also used in refrigerators, air conditioners, and water heaters. In contrast, king valves are used primarily in plumbing systems to control water flow. Still, they are also useful for shutting off the water supply to the building in case of emergency.
Which one should you choose?
Choosing between a service valve and a king valve depends on the type of system you’re installing or repairing. However, a general rule of thumb would be to use service valves when regulating the flow of refrigerant, gas, or other fluids in an appliance. King valves are best when you need to control the water supply of your building or plumbing system.
In conclusion, understanding the differences between service and king valves is essential when repairing or installing plumbing and HVAC equipment. While both valves control the flow of fluids, service valves are more accessible, easier to use, and often used in appliances such as refrigerators and air conditioners. In contrast, king valves are used primarily for controlling the water supply to the building. Now that you know their differences, you can choose the right valve for your needs.
