Complaint
Single orifice exhaust valve (exhaust valve) is used for pipe exhaust of independent heating system, centralized heating system, heating boiler, central air conditioning, floor heating and solar heating system. Because water usually contains a certain amount of air, and the solubility of air decreases with the increase of temperature, gas gradually separates from the water during the circulation process and gradually gathers together to form large bubbles or even gas columns. Due to the supplementation of water, gas is often generated.
Application
The air vent valve is applicable to be the equipment of quickly discharging air in pipe of industrial medium being water. It is for improving the efficiency of water transporting equipment and protecting pipe free of distortion of damage, so it is the pre-requisite equipment for pipe.Features
1. It can eliminate air in pipe so as to decrease resistance and save energy.Technical Parameters
