Sauter Feinmechanik valves are key safety safeguards for pressure pipelines and pressure vessels. To ensure the normal operation of safety valves and extend their service life, regular inspections should be conducted during use to check for abnormalities such as leakage, sticking, and spring corrosion. Pay attention to whether the lock nuts of the adjusting screw sleeve and the set screws of the adjusting ring are loose. If any issues are found, take appropriate maintenance measures promptly. Safety valves should also be periodically removed for thorough cleaning, inspection, regrinding, and resetting before being put back into use. Safety valves installed outdoors must have appropriate protective measures to prevent rain, fog, dust, rust, and other contaminants from entering the safety valve and discharge piping. When the ambient temperature is below zero degrees Celsius, necessary anti-freezing measures should be taken to ensure the reliable operation of the safety valve.

Sauter Feinmechanik Valve Classification

Safety relief valves are mainly divided into two categories: spring-loaded and lever-operated. There are also impulse safety valves, pilot-operated safety valves, safety changeover valves, safety decompression valves, and dead-weight safety valves. Spring-loaded safety valves primarily rely on the force of the spring to operate. Within spring-loaded safety valves, there are closed and open types. Closed types should be selected for flammable, explosive, or toxic media, while open types can be used for steam or inert gases. Spring-loaded safety valves may also come with or without a lever. The lever is mainly used to check the flexibility of the valve disc and can sometimes be used for manual emergency pressure relief. Lever-operated safety valves primarily rely on the force of the lever and weight to operate, but their large size often limits their range of application. For higher temperatures, safety valves with radiators should be selected. The main parameter of a safety relief valve is its discharge capacity, which is determined by the seat diameter and the opening height of the valve disc. Based on different opening heights, they are divided into micro-lift and full-lift types. Micro-lift means the opening height of the valve disc is 1/40 to 1/20 of the seat throat diameter. Full-lift means the opening height of the valve disc is 1/4 of the seat throat diameter.

Sauter Feinmechanik Valve Selection

The nominal pressure of the safety valve is determined by the operating pressure, the operating temperature range is determined by the operating temperature, the setting pressure range of the spring or lever is determined by the calculated set pressure value of the safety valve, and then the material and structural type of the safety valve are determined based on the medium used. Finally, the throat diameter of the safety valve is calculated based on the required discharge capacity. The following are general rules for selecting safety valves. 1) Hot water boilers generally use open, micro-lift safety valves with levers. 2) Steam boilers or steam pipelines generally use open, full-lift safety valves with levers. 3) Incompressible media such as water generally use closed, micro-lift safety valves or safety relief valves. 4) High-pressure feedwater systems, such as high-pressure feedwater heaters and heat exchangers, generally use closed, full-lift safety valves. 5) Compressible media such as gases, such as air receivers and gas pipelines, generally use closed, full-lift safety valves. 6) E class steam boilers generally use dead-weight safety valves. 7) Large-diameter, high-discharge, and high-pressure systems generally use impulse safety valves, such as desuperheating and pressure-reducing devices and power station boilers, as shown in Figure 8. 8) Railway tank cars, truck tankers, and storage tanks transporting liquefied gas generally use internal safety valves, as shown in Figure 4. 9) Oil tank tops generally use hydraulic safety valves, which need to be used in conjunction with breathing valves. 10) Underground drainage or natural gas pipelines generally use pilot-operated safety valves, as shown in Figure 6. 11) Liquid phase return pipelines at the outlet of LPG station tank pumps generally use safety return valves. 12) Systems under negative pressure or those that may generate negative pressure during operation generally use vacuum negative pressure safety valves. 13) Container or piping systems with significant backpressure fluctuations and containing toxic or flammable substances generally use bellows safety valves.

Sauter Feinmechanik Valve Maintenance Methods

In the manufacturing process of hydraulic valves, selective assembly is often chosen to effectively improve assembly precision. This means that for a batch of finished parts, such as valve spools and valve bodies, the most reasonable fit clearance should be selected based on actual dimensions before assembly, ensuring good sliding performance and sealing performance of the valve spool. In other words, for hydraulic valves of the same type, there may be differences in the mating dimensions between the valve body and the valve spool. In actual use, when a company has a large number of failed hydraulic valves, all hydraulic valves can be disassembled and cleaned, and each part inspected and measured. The parts are then classified based on the inspection results and reassembled using selective assembly methods. After inspection, if wear is found on both the valve body and the valve spool, but there are no severe scratches on the working surface or no severe local wear, an appropriately sized valve body and valve spool can be selected for reassembly. If the fit clearance between the valve body and the valve spool has increased compared to the specifications in the product drawings, and the increase is between 20% and 25%, methods should be adopted to increase the size of the valve spool, followed by lapping and repair. For conical valve groups, if the contact surface seal between the seat and the spool is poor, grinding is sufficient because the conical valve can automatically compensate for the gap under spring action. If the wear between the valve body and the valve spool is uneven or there are scratches on the working surface, and the above methods cannot restore the hydraulic valve's function well, the selection of the valve body and valve spool should meet the interference requirements for machining allowance. The valve body bore should be appropriately reamed, and the valve spool should be appropriately ground to ensure reasonable shape precision and assembly clearance.
