Brass or stainless steel valve body, float and valve core are made of brass for high temperature resistance, high pressure resistance and corrosion resistance.
Differential pressure working principle, only inhale but not exhaust, flexible opening and closing;
No need for manual operation, automatic inhalation action, sensitive replenishment, sufficient air intake.
The internal sealing parts are all tapered hard seals, which makes up for the shortcomings of the previous products that used plastic or rubber rings to seal;
There is a slight noise when the float moves, and no sound can be heard from one meter away; no environmental noise will be formed.
Use medium: suitable for heat pipes or steam pipes or tap water pipe systems to eliminate vacuum destructive power.
Medium temperature: 0-150℃
Nominal pressure: 0 6Mpa-1.0Mpa
Floating in sealing pressure: 0.02～0.6Mpa
Body material: brass or stainless steel
Application standard: GB/T12225 Taijin casting conditions
The pressure test shall comply with the requirements of the Taiwan Standard GB/T13927-2008.
When the pressure of the pressured piping system disappears, if the outside air is not sucked into the system, it will inevitably cause a vacuum in the piping to generate negative pressure, which will damage the piping system and even cause an explosion hazard. The suction valve can quickly inhale a large amount of outside air when the system pressure disappears, so that the pressure in the system is balanced with the atmospheric pressure to ensure that the pipeline system will not be damaged by negative pressure. It is an accessory that can maintain a stable pressure in the pipe without a vent pipe. Set at the highest end of each layer of horizontal branch pipes or the top of stand pipes separated by several layers. Therefore, the suction valve is an indispensable auxiliary component for reducing negative pressure in the piping system, and is widely used in high-rise building heating systems, plant piping, small pumping stations and other pressure pipelines and thermal steam pipelines that use antifreeze devices. It is often set at the highest point or local highest point of the pipeline system to automatically close and open, so that the pressure difference between the inside and outside of the pipeline is equal, and the consumption of vacuum damages the pipeline or equipment.
When installing the suction valve, install it vertically. When the system pressure disappears, the floating pellet will settle under the dual force of the gravity system and automatically open the air inlet. The air enters the pipe through the cylinder air inlet. When pressure is generated in the piping system, the float rises under the action of the system pressure to safely block the air inlet of the cylinder. The suction valve is now completely closed.
