Hongsen UL Listed 1/4 ODF Brass Ball Valve
Designed for refrigeration and HVAC systems, this valve is UL listed for safety and reliability. It undergoes helium leak testing to ensure a dependable seal, and its forged brass body resists corrosion for long service life. The precise sealing seat supports tight shutoff, reducing refrigerant leakage and helping maintain system efficiency in demanding environments.
Midline Valve 5 Pack 1/2″ Brass Gas Ball Valves
This 5-pack features a 1/2″ OD flare to 1/2″ FIP configuration with a tight, leak-free seal ideal for gas line applications. The durable forged brass body houses a stainless steel ball for improved strength and corrosion resistance. It is rated for up to 600 PSI WOG and supports a broad temperature range, suitable for residential and commercial uses.
Nigo 101SS Series 1/2″ Full Port Ball Valve
The Nigo 101SS Series uses a full-port design and a lever handle for easy operation. It is certified to ANSI/NSF 372 and California AB 1953, meeting lead-free requirements for potable water applications. The valve’s construction prioritizes reliability in service with straightforward servicing and a robust full-port pathway for minimal pressure drop.
Hongsen UL Listed Brass 3/4 ODF Ball Valve
UL listed for safety and reliability, this 3/4 ODF valve is built for demanding refrigeration and HVAC environments. It features a wide operating range, handling medium temperatures from -40℃ to +120℃. The forged brass body offers exceptional durability and resistance to corrosion, supporting long service life in challenging conditions.
YADIAN 4 Pack 1/2″ Stainless Steel Ball Valves
These stainless steel 304 ball valves offer a full-port design with NPT female ports and a locking device for added security. The PTFE (teflon) seals provide excellent corrosion resistance and a long service life in water, oil, and gas applications. The valves are designed for serviceability and easy maintenance.
Buying Guide
Material and Certification
Choose valves with materials appropriate for your system. Brass is common in HVAC and refrigeration, while stainless steel offers higher corrosion resistance for water and chemical lines. Look for UL, ANSI/NSF 372, and California AB 1953 lead-free certifications to ensure safety and compliance.
Port Size, Connections, And Pressure
Match port size to your piping (e.g., 1/4″, 1/2″, 3/4″ OD/IPS). Consider full-port designs for reduced flow resistance. Check WOG (water, oil, gas) and WSP ratings to ensure the valve meets system pressure and temperature requirements.
Sealing And Durability
Look for leak-tested components, precision seating, and durable bodies (forged brass or stainless steel). Leaktight seals reduce refrigerant loss and improve efficiency in HVAC and refrigeration systems.
Serviceability And Maintenance
Full-port and serviceable valves allow cleaning or replacing seals without complete disassembly. Locking devices or secure handles can be beneficial for installations requiring tamper resistance or safety compliance.
Application Fit
Consider your primary use: HVAC/refrigeration, potable water, or general gas lines. Ensure the valve configuration (OD flare, FIP, or NPT) matches the system fittings and is compatible with your installation method (solder, flare, or threaded connections).
