A high-quality safety valve can only exert the best overpressure protection effect with correct selection, standardized installation and scientific daily maintenance. Many industrial equipment safety hidden dangers are caused by improper safety valve type selection, non-standard installation and untimely maintenance. To help customers use safety valves correctly and extend the service life of equipment, CHOWHANG sorts out professional selection, installation and maintenance guidelines based on years of industrial service experience, providing practical operation guidance for enterprise equipment management.

First, scientific type selection is the premise of safe operation. Users need to determine the matching safety valve type and parameters according to the actual working conditions. First, confirm the medium type: gas and steam medium is suitable for full-lift spring safety valves, liquid medium is preferred for micro-lift safety valves, and high-precision pressure control scenarios need to choose pilot-operated safety valves. Second, clarify the working parameters, including rated working pressure, maximum allowable overpressure, working temperature range and pipeline caliber, to ensure that the set pressure and discharge capacity of the safety valve match the equipment system. In addition, for special working conditions such as strong corrosion, high temperature and low temperature, it is necessary to select safety valves with corresponding material and structural optimization. If you have difficulty in type selection, you can obtain one-to-one professional type selection service from CHOWHANG technical team to avoid equipment safety risks caused by wrong type selection.

Second, standardized installation ensures stable valve performance. During the installation ofCHOWHANG Safety Valves, the installation direction must be strictly followed to ensure vertical installation and avoid tilting, which will affect the pressure response and reset effect. The inlet pipeline of the safety valve should be kept unobstructed, and no valves or blocking parts are allowed to be installed to ensure that the pressure can be transmitted in real time. The discharge pipeline should be reasonably arranged according to the medium characteristics: flammable, explosive and toxic media need to be connected to the recovery and discharge system, and steam and gas media need to ensure smooth discharge. After installation, a pressure test and sealing inspection must be carried out to confirm that the valve opens and resets normally and there is no medium leakage.

Third, daily maintenance and regular inspection extend service life. In daily operation, enterprises should establish a regular inspection mechanism for safety valves. It is necessary to regularly check whether the valve body has leakage, deformation and corrosion, whether the spring and sealing parts are aging and damaged, and whether the pressure setting value is offset. For safety valves operating in high-frequency and harsh working conditions, regular pressure calibration and performance testing are required to ensure that the opening pressure and discharge capacity meet the standard requirements. In addition, dust and dirt on the valve body should be cleaned regularly to avoid blockage of internal parts affecting the pressure relief function. Long-term unused safety valves need to be tested and debugged before reuse to ensure normal operation.

As a professional safety valve manufacturer, CHOWHANG not only provides high-quality safety valve products, but also supports customers with full-cycle technical services including type selection guidance, installation guidance, technical training and after-sales maintenance. We help customers standardize equipment management, eliminate potential safety hazards, and ensure the long-term stable and safe operation of industrial pressure systems.
