Brass Automatic Drain Valves With Pressure Relief Valve For Solar Water Heater Automatic Exhaust Valve(25mm Interface, DN20)

Brass automatic drain valves with pressure relief valve for solar water heater Automatic exhaust valve

Style specifications and dimensions: 25mm interface, DN20

Material High Quality: Our solar water heater pressure reducing valve is made of high quality brass, the inside is cast with high precision parts, and the drainage mechanism is stable and reliable.

Automatic design: When the system water supply or system pressure is too high and needs to be drained completely, the automatic pressure limiting valve can work reliably. The purge valve will continue to purge as long as there is a pressure difference between the inside and the outside of the system.

Easy to disassemble: to ensure that water does not flow not during the water discharge process, our automatic drain valve adopts a special structure and adopts the design of steam-water separation disc. Easy to disassemble and maintain, so the system does not need to be emptied

Application: The solar quick exhaust valve is used to exhaust excess air during system operation exhaust valve and HLK system.It has the characteristics of high temperature resistance, rust prevention and reliable sealing.

Selection of automatic exhaust valve:

< p>A certain amount of air is generally dissolved in the fluid medium of the pipeline, and the solubility of air decreases with the increase in temperature, so that the gas is gradually separated from the water during circulation water, and gradually collects to form large bubbles or even gas. Due to the additional water, gas is often generated in the column. At this time, it is necessary to use the exhaust valve to dump excess gas into the pipeline to ensure the proper flow of the medium. 【Automatic brass exhaust valve】Applies to the pipeline exhaust of independent heating system, central heating system, heating boiler, central air conditioner, floor heating and heating system solar.
