5 FAQs About Snook & Aderton HVAC Valves
1. How do I determine which valve is correct for my system?
Selecting the correct valve depends on multiple factors, including:
-
Application Type – Are you replacing a gas valve in a furnace, installing an expansion valve in an AC system, or controlling water flow in a boiler?
-
Valve Size & Connection Type – Check the inlet and outlet size (e.g., 1/2" x 1/2") to ensure compatibility with your existing pipes or fittings.
-
Fuel or Refrigerant Type – Some valves are specifically designed for natural gas, propane, R-410A refrigerant, or water applications.
-
Voltage & Power Requirements – If selecting a solenoid or electric control valve, ensure the voltage (e.g., 24V, 120V) matches your system’s specifications.
-
Operating Capacity – HVAC valves have different BTU ratings or flow capacities; choosing the correct size prevents performance issues and inefficiencies.
If you're uncertain, contact our team with your system details, and we’ll help you find the right valve.
2. Do your valves come with warranties?
Yes, all the valves we carry come with manufacturer warranties, though the coverage length varies by brand and model. Most brands provide warranties ranging from one to five years, covering defects in materials and workmanship.
Additionally, we ensure that all our valves meet industry safety and performance standards, so you can trust their durability and reliability. If you have any warranty-related concerns, our team is available to assist with claims or replacements.

-
Installation Tips – While professional installation is recommended for gas and refrigerant valves, we can provide basic guidance on installation procedures and safety precautions.
-
Troubleshooting Assistance – If you experience issues with your HVAC valve, we can help identify possible causes and recommend solutions.
4. What are the typical operating temperature and pressure ranges?
Gas valves in HVAC systems are engineered to perform in a wide range of temperatures. For example, many gas valves are designed to operate reliably from as low as –20°F up to 150°F.
The operating pressure for these valves is usually around 3 to 7 inches water column (WC), though water and refrigerant valves may have different ranges. Detailed specifications can be found in the product datasheets, which help you match the valve to the specific environmental conditions of your HVAC system.
5. What certifications and standards do your valves meet?
Our valves are built to meet stringent industry standards and often carry certifications such as UL, CSA, and ISO. These marks indicate that the products have been tested for safety, durability, and performance under various conditions.
Many of our valves also comply with AHRI standards, ensuring they operate efficiently within HVAC systems while meeting regulatory requirements.
6. How do I determine the correct valve size and flow rating for my system?
Determining the correct valve size begins with accurately measuring your existing pipe or connection dimensions, which are commonly 1/2" or 3/4". You should also refer to the inlet and outlet specifications provided in the product details.
Performance charts from the valve manufacturers can help match your system’s required flow rate to the appropriate valve size and capacity, ensuring that the valve can handle the necessary BTU or refrigerant flow.
7. What wiring and control signal requirements do solenoid valves have?
Solenoid valves require specific wiring and voltage setups to operate correctly. They are typically available in voltage options such as 24V, 115V, or 230V, and it is essential to verify the correct voltage for your system by checking the product label or datasheet.
Detailed wiring diagrams provided by the manufacturer must be followed carefully, including verifying coil resistance, correct polarity, and secure connector usage to ensure proper functionality.85. What maintenance practices help ensure valve longevity and optimal performance?
Regular maintenance of HVAC valves involves routine inspections to check for wear, leaks, or corrosion on the valve body, seals, and wiring—especially for solenoid valves. It is important to remove any dust, debris, or buildup that could interfere with the valve's operation.
