1.The GKPQ242X Combination Air Valve is a two-valve assembly consisting of an air & vacuum valve and an Air Release Valve. The combination allows the valve to exhaust large amounts of air at start-up, to release small pockets of air while the system is running, and to prevent critical vacuum conditions during draining. The Kinetic feature prevents the valve from blowing shut before all the air is vented. For additional configurations, see Product versions below. 
Product features and benefits
Rugged and corrosion resistant
Drop tight seating
Full length guides ensure proper seating
Spherical, stainless steel float
Rubber cushions protect float from damage
Ensures complete purging of all air prior to valve closure

2.AV861 Slow closing  double chambers Surge-suppression Air valve
Manufactured under a certified ISO 9001 quality system
Provides full vacuum protection for the pipeline
Provides controlled venting to suppress surges in pipeline
Minimizes water blow-by during Air Valve closure
Allows the use of smaller valve size by utilizing a maximum sizing differential pressure of 5 psig
Releases entrained air while pipeline is operating to maintain pumping efficiency
Air Release valves function to release air pockets that collect at each high point of a pressured pipeline. Air Release Valves can open against internal pressure, because the internal lever mechanism multiplies the float force to be greater than the internal pressure. This greater force opens the orifice whenever air pockets collect in the valve. Air Release Valves are essential for pipeline efficiency and water hammer protection.

 
Restrictor disc provides regulated exhaust to limit secondary surges during column separation
Ability to adjust air exhaust for greater surge suppression
Provides full vacuum flow port for maximum pipeline protection 
Applications for Tianjin U-ideal float-type air vents include hydronic heating systems, water service lines, water storage tanks, centrifugal pumps, gas lines, solvent filters and similar equipment. Operation is completely automatic, and the simple design and quality mechanism make operation trouble-free and maintenance infrequent.

Why remove air from a water system?
Every building services engineer knows that air trapped in either a hot or chilled water system can cause
trouble, such as excessive noise, corrosion and increased maintenance costs. Air can cause air locks which inhibit the filling of the system or the priming of pumps. It can seriously affect the accuracy of flow measurement meters and regulating valves. Under extreme conditions it may even temporarily decommission plant. Air and other incondensable gases considerably reduce heat transfer efficiency. A film of air 1 mm thick presents the same barrier to heat transfer as a wall of copper 13 m thick!
Entrapped air in any water system is a threat to thermal efficiency. It is particularly damaging in a chilled water system which does not have the natural deaerating ability of hot water.
