Product Features
1. Core Functions
1)Valve Port Sealing and Valve Core Positioning:It is the core sealing component of valves. It is embedded in the valve seat. It closely fits the valve port and valve core through its stepped structure. It blocks fluid medium leakage. It also assists in fixing the valve core position. It ensures the precise opening and closing of valves. This is an essential performance for the sealing system of Sealed Diaphragm Pump and Sealed Fluid Transfer Pump.
2)Corrosive Medium Isolation:It works under conditions in contact with corrosive fluids such as acetic acid. It effectively isolates the medium from the metal valve seat. It avoids corrosion damage of the valve seat. It extends the service life of valves.
3)Buffer Protection in High-Temperature Working Conditions:It takes advantage of the elasticity of silicone. It cushions the mechanical impact during the opening and closing of the valve core. It maintains the stability of the sealing structure in high-temperature environments. This is a core advantage of Fluid-Tight Diaphragms and Sealing Elements for Valves in harsh working conditions.
2. Performance Characteristics
1)Silicone Material + 80°±5 Hardness, Adapted to Severe Working Conditions:It is made of special acetic acid-resistant silicone. It has excellent tolerance to corrosive media such as acetic acid. The 80°±5 high hardness setting ensures sufficient structural rigidity. It supports the valve core stably. It also retains good elasticity. It fills microscopic gaps for reliable sealing. It perfectly adapts to the precision sealing needs of Micro Sealed Hydraulic Pump and miniature fluid control valves.
2)Superior Resistance to High-Temperature Acetic Acid:It can withstand long-term corrosion of high-temperature acetic acid. It has no swelling, hardening or cracking under such conditions. It maintains stable performance in chemical industry, food processing and other scenarios in contact with acetic acid.
3)Low Compression Set for Long-Lasting Sealing:The silicone material has outstanding rebound performance. It maintains a stable sealing force even under long-term compression. It has no slack or failure during use. It eliminates the need for frequent replacement. It reduces equipment maintenance costs.
4)Stepped Structure for Precise Sealing Fit:The stepped cylindrical design fits the mating surfaces of the valve seat and valve core with high precision. It has a larger sealing area compared with ordinary flat rubber heads. It has higher sealing reliability compared with ordinary flat rubber heads. This is a key design advantage of Gasket & Membrane Assemblies for precision fluid control.
3. Application Scenarios
1)Small Acetic Acid Conveying Pipeline Valves:It is suitable for miniature globe valves and check valves with a caliber of about 5mm. It is used in acetic acid conveying pipelines in laboratories and small food processing plants. It serves as the valve core sealing rubber head for these valves.
2)Portable Vinegar Detection Equipment:It is used for the sealing of sampling valves in portable acetic acid concentration analyzers. It is applied in the food detection field. Its small size adapts to the compact internal structure of the equipment.
3)Miniature Chemical Fluid Control Valves:It is used in micro-chemical systems. It acts as the sealing rubber head of miniature solenoid valves and needle valves in contact with high-temperature acetic acid. It meets the control requirements of small flow and high precision in such systems.
4)Household Vinegar Brewing Equipment:It is adapted to the drain valves and circulation valves of small household vinegar brewing machines. The food-grade silicone material ensures the hygiene of the brewing process.
5)Medical Reagent Pipeline Valves:It is used for miniature valves in biochemical reagent conveying pipelines. The pipelines contain acetic acid components. Its small size adapts to the flow channel design of precision medical equipment.
4. Pain Point Solutions
1)Solves Sealing Failure Caused by Corrosion:Ordinary rubber heads are not resistant to acetic acid corrosion. They are prone to swelling and aging under acetic acid contact. This leads to valve leakage. The acetic acid-resistant silicone material of this product achieves long-term reliable sealing. It is for valves in acetic acid medium. It optimizes the performance of Sealed Fluid Direction Control Valve in corrosive working conditions.
2)Resolves Hardness Attenuation at High Temperatures:The hardness of ordinary silicone drops rapidly at high temperatures. This causes the valve core to loosen. The 80°±5 high hardness design maintains structural rigidity even at high temperatures. It ensures the stable positioning of the valve core. It guarantees the working stability of Mini Sealed Valve in high-temperature environments.
3)Addresses Imprecise Sealing Fit:Flat rubber heads have a small fitting area with the valve seat. They are prone to leakage during use. The stepped structure of this product increases the sealing area with the valve seat and valve core. It significantly improves sealing reliability. It enhances the use effect of Fluid-Tight Diaphragms in precision valve sealing.
4)Eliminates Frequent Replacement:Inferior rubber heads have a short service life. They bring high maintenance costs for equipment. The low compression set characteristic of this product extends the service life of the sealing rubber head. It reduces the frequency of maintenance and replacement. It lowers the use cost of Pressure Seal Components in fluid control systems.
