Automatic air vent valve in brass with silicone rubber plug
Automatically dispose of trapped air bubbles in a system
Includes manual venting outlet
Compact design to allow installation in applications with limited space
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.
These Air vent are compact float-type valves for the removal of air and other gases from hydronic heating and cooling systems, liquid chilling operations, and other light liquid services.
The Air vent valve is designed to release air-pockets out of the piping system.I t should be installed at every high-point of the piping system where air can be trapped. The simple construction relies on a float held by a lever,so that the float does not rub against the body to avoid any risk of jamming.
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.

Air Valves vs. HydrantsÂ
There is a common misconception that fire hydrants can be used in place of combination air valves to provide the required air-release service. This method should be strongly discouraged for several reasons:Â
The use of fire hydrants requires active user intervention, which creates a hidden maintenance cost. In order to be effective, the hydrants should be discharged once per day. At just five minutes per hydrant at a rate of $10.00 per hour, a small town with twenty hydrants would spend more on the labor used than it would have spent on twenty automatic air valves.Â
Manual air release cannot accommodate surges in flow or demand. Only automatic air valves can provide the needed functions on demand in order to protect the water system.Â
Hydrants cannot provide the vacuum-breaking function required to prevent contamination during negative-pressure events. Automatic air valves help protect the finished water at all hours, every day of the year.Â
The pressures accumulated within the hydrant, even at a system pressure of 80 psi, can be extremely hazardous to maintenance workers. Accumulated pressures in some systems can reach more than ten times the rated system water pressure. Automatic air valves work without user intervention and prevent the accumulation of pressure.Â
Hydrants are typically mounted to the sides of a main (at the 3 o'clock and 9 o'clock positions), rather than at the top. This can significantly reduce their effectiveness as air-release devices, even when flanged at the full diameter of the main. Automatic air valves are properly installed only at the top (12 o'clock) position, where they can provide complete discharge of accumulated air.Â

1 Ton Pedestrian Type Electric Stacker
Electric Stacker is an industrial device for loading and lifting pallets on a shelf at high level. As an ideal choice to operate in narrow space of warehouse, it can be widely used in petroleum, chemical, pharmaceutical, textile, pigment, coal and other industries, as well as ports, railways, freight yards, warehouses.
1. Mast which can provide wide field of vision
The hydraulic cylinder is located at the right-middle side of the stacker, thus
providing a wider field of vision for the operator.
2. Double speed switch
The speed of this electric stacker can be freely switched between normal speed
and slow speed. The operators can choose slow speed to realize slow moving of the
stacker. This is especially suitable for new operators who are not familiar
with the operation of this equipment.
3. Lateral vertical moving
The stacker can move without pulling the handle. By pressing down the straight
moving button, the stacker can move slowly. This is suitable for working in
narrow aisles and other limited spaces.
4. Adjustable balance and supporting wheel
The adjustable balance wheel features strong stability, so that the operation
can be more stable, safer and more reliable.
5. Solid channel steel mast
Compared with the bending finished iron metal mast, the channel steel mast is
more solid and durable, more stable and safer.
6. Intelligent sleep mode
When the stacker is not in use for long time, the intelligent sleep mode will
be automatically initiate to save battery power and cost.
7. Handle of the best one-step length
The long operating handle adopts ergonomic design. The max ground clearance is
1305mm and the min ground clearance is 715mm, so that it quite easy to use.
During normal operation, the operators should be one-step away from the
stacker, so that their feet will not get caught by the wheel, thus ensuring
safety of the operators.
8. Split type mast
The fabricated connection of the mast and stacker frame can realize easy installation
and changing of the mast as necessary. The working device and moving device are
easily disassembled and changed.
9. Beautiful and tiny appearance
The base design: the front base is 600mm in length so that it is flexible and
suitable for working in narrow channels. It is the ideal choice for trans-floor
working.
