All-weather Breathing Valve HXF-I

Product Overview

All-weather breathing valves are a safe and energy-saving product designed to maintain pressure balance in storage tanks and reduce medium volatilization. These valves make full use of the tank's inherent pressure-bearing capacity to minimize medium emissions.

The principle is to control the storage tank's exhaust positive pressure and suction negative pressure by utilizing the weight of the positive and negative pressure valves; when the medium is extracted from the tank, causing the pressure in the upper gas space inside the tank to drop, reaching

When the breathing valve operates under negative pressure, the external atmosphere will lift the negative pressure diaphragm of the breathing valve, allowing external gases to enter the tank, thereby preventing the pressure inside the tank from continuing to drop. When filling the tank with...

Introduce the medium, the internal pressure of the tank increases to reach the set positive pressure operating pressure. The gas is then discharged through the positive valve disc, allowing the pressure inside the tank to equalize with the external pressure, thereby protecting the tank's safety devices.

The new all-weather breathing valve housing is made of stainless steel and cast steel for excellent corrosion resistance; the valve disk is made of PTFE material, with good low-temperature resistance and frost prevention; the structure is simple, easy to maintain, and safe.

Convenient; the new all-weather breathing valve meets the requirements of the Ministry of Petroleum Industry standard SY7511.1-2010.

Key Features

This valve features large air volume, excellent sealing performance, low leakage, corrosion resistance, and explosion-proof characteristics.

Product Maintenance

1. Check if the pressure valve disc and vacuum valve disc operate smoothly, and ensure that the guide rod and valve sealing ring have no damage upon contact with the hundred.

2. Ensure a tight fit and smooth movement of the guide rod when reinstalling the pressure plate and vacuum plate.

3. When activating the new all-weather breathing valve, it is necessary to remove the anti-vibration materials from the disk.

4. Our company's breathing valves come with plastic protective caps on both the inlet and outlet at the factory to prevent damage to the flanges during transportation. Please remove the protective caps when installing.
