Features and Benefits
Combination Air Valves perform the functions of an Air/Vacuum Valve and Air Release Valves to maintain system efficiency and prevent pipeline surges.
Able to release air at high flow rates.
High sensitivity: when negative pressure occurs inside pipelines, valves rapidly open to inhale large volumes of air and protect the pipelines from damage.
Floating ball and main disc are in stainless steel.
This provides long service life, safety and reliability.

Fasteners are the general term of the class of mechanical parts used in fastening two or more parts (or components) into a whole. It is widely used in energy, electronics, electrical appliances, machinery, chemical, metallurgy, mold, hydraulic and other industries, at the same time, in various kinds of machinery, equipment, vehicles, ships, railway, bridge, construction, structure, tools, instruments, chemical, instruments and supplies, you can see all kinds of fasteners, is the most widely used mechanical foundation parts. It is characterized by a wide variety of variety specifications, different performance uses, and a very high degree of standardization, series, and generalization. Therefore, a class of fasteners that already have national standards is called standard fasteners, or simply standard ones.
