Mini ball valves are compact shut-off valves used in applications with limited space, controlling water, gas, air, and oil in domestic and industrial settings such as plumbing, irrigation, HVAC, and small-scale gas and oil lines. Their compact design, quarter-turn operation, and ability to handle varying temperatures and pressures make them ideal for tight spots and space-saving processes where larger valves are impractical.
Common Applications
Plumbing and Domestic Systems: Used in residential and light commercial water systems, including domestic hot and cold water, and for controlling gas flow from natural or bottled gas lines.
Irrigation: Control water flow in smaller irrigation systems.
HVAC Systems: Control the flow of chilled or hot water in heating and air conditioning plants.
Compressed Air Systems: Regulate the flow of compressed air in various applications.
Oil and Gas: Manage the flow of oil in engine coolers and for isolating lines in industrial oil and gas applications.
ndustrial Processes: Control various fluids, including process chemicals, steam, and multi-fluid applications, particularly where space is a constraint.
Key Characteristics
Compact Size: Their small size makes them ideal for tight and confined spaces where conventional valves won't fit.
Quarter-Turn Operation: They open and close with a simple 90-degree turn of their lever handle.
Threaded Connections: Many have threaded ends (male and female) for easy integration into existing pipework.
Durability: Often constructed from materials like stainless steel or brass, they are durable and can operate reliably under high-pressure and high-temperature conditions.
Versatility: Can handle a wide range of media, including water, gas, oil, solvents, and even vacuum, depending on the valve's material and design

Q: Is there a warranty available?
A: Yes, normally products is one year quality guarantee.
Q: Is the connector in British or Metric system? What is the difference between PT, NPT, and G threads?
A: The G thread is cylindrical and does not seal itself, requiring additional gaskets to prevent leakage. PT and NPT are conical, and the internal and external threads become tighter and tighter when tightened. Sealing is achieved through the deformation of the threads, and sealant or tape is usually used in conjunction to enhance the sealing effect
G-thread is a cylindrical straight pipe used for non sealed connections; PT thread is a conical tube that relies on the deformation and sealing of the thread itself; NPT is also a conical tube with a tooth profile angle of 60 degrees, mainly used in North America
Q: How to convert pressure units: MPa, bar, psi, kg/cm ²?
A: 1MPa=10bar≈145psi≈10kg
Q:What usually causes the burnout of solenoid valve coils?
A:Incorrect voltage and hz, frequent switching, pilot head entering liquid,valve core and spring problem,environment hot,heavy vibration etc.
