Soft seals provide a high degree of tightness, but can wear out quickly with frequent use or when working with aggressive environments. Metal seals : Made of various metals and alloys (stainless steel, bronze) and are used in conditions of high temperatures and pressure. Such seals are used in systems with special requirements for tightness and durability. Soft seals: Made of elastomers (rubber, EPDM, silicone) and are used in systems with low temperatures and pressure. Metal seals have high wear resistance and durability, but can be less airtight compared to soft seals.

Combined seals: Combine elements of soft and metal seals, providing an optimal balance between tightness and wear resistance. The spindle remains fixed in an upright position, regardless of the lattice's state. Advantages: КомпактністьCompactness: Latches with a retractable spindle take up less space, which is especially important in limited spaces. Simplicity of the design: A smaller number of moving elements reduces the likelihood of mechanical malfunctions and simplifies installation.

Disadvantages: Lack of visual control : Determine the condition of the latch (open or closed) can only be by indicators or special marks on the drive. Wear and corrosion: Spindle is in constant contact with the working environment, which can lead to its rapid wear and corrosion, especially when working with aggressive environments. Design and principle of operation: In latches with a non-retractable spindle, the spindle rotates in place, and the locking element rises and descends along the guides inside the housing.

Operating conditions: The temperature, pressure and chemical composition of the working environment determine the choice of the seal material and the spindle type. Spatial constraints: The presence or absence of free space for installing a latch can be a decisive factor when choosing between a retractable and non-retractable spindle. Service requirements : Latches with a retractable spindle are easier to maintain, but they require more space, while latches with a non-removable spindle are more compact, but more difficult to maintain.

Tightness and durability: The choice between soft, metal or combined seals depends on the tightness requirements and the life of the latch. Pipe damage: Sharp pressure surges can cause destruction or breaking of pipes, Клапан запорный проходной штуцерно-торцевой Dn15 Pn64 (admiralzavod.ua.market) especially if they are made of fragile materials. Damage to the reinforcement: Valves, latches and other reinforcement components may fail due to excessive loads. Violation of tightness: Hydroguard can lead to leaks, which is especially dangerous when transporting aggressive or dangerous substances.

Reducing the efficiency of the system: Frequent hydraulic shocks can lead to shutdowns of the system and the need for frequent repairs, which reduces its overall efficiency and reliability. Water supply of cities: In water supply systems of large cities, dampers and air chambers are often used to prevent water hammers. This allows for uninterrupted water supply and reduce the risk of accidents. Industrial pipelines: In the petrochemical and gas industry, the installation of check valves and dampers is a standard practice.
