Product details

This is a rubber gasket for solenoid valve. It’s used for industrial automated production lines in pump-valve systems. It’s a critical part of Diaphragms & Sealing Gaskets and Sealing Elements for Valves in industrial fluid control.It’s made specifically to work with Mini Sealed Valve and Sealed Fluid Direction Control Valve in automated workflows. It has an irregular polygonal shape. The edges of this shape have chamfers. This design is tailored to fit the non-standard structure of the solenoid valve’s specific sealing cavity. It makes sure the gasket fits precisely with the sealing surface.The central hole of the gasket uses a card-slot design. There’s a small central protrusion in this hole. This design matches the corresponding structures of the solenoid valve core and stem. It does two main things: first, it helps guide and position the gasket. Second, it makes the sealing better by matching the shapes of the valve parts.The gasket has a thin thickness. Usually, it’s 1–3mm thick. Its surface is very flat. This makes sure there are no gaps when it touches the sealing surface. It reduces the risk of leakage. Its structural precision meets the strict requirements of Pressure Seal Components and Gasket & Membrane Assemblies in high-reliability industrial systems.

Product Features

1. Functions

1)Sealing and Leakage Prevention:It fills the gaps between solenoid valve components. Like the valve body, valve core, and pipeline interfaces. It blocks fluids (liquids or gases—such as hydraulic oil, compressed air, chemical media) from leaking. This makes sure industrial automated production lines control fluids accurately. This is a core requirement for Fluid-Tight Diaphragms and Sealed Fluid Transfer Pump supporting systems.

2)Cushioning and Protection:Solenoid valves open and close very often in some situations. Like in automated production lines where they act continuously. During this process, the gasket absorbs the impact between the valve core and valve body. It slows down wear on the components. This makes the solenoid valve last longer. This protective role helps meet the durability needs of Micro Sealed Hydraulic Pump and other critical parts of automated equipment.

3)Media Isolation:It separates different media or environments. For example, it stops external dust and moisture from getting into the solenoid valve’s interior. This keeps the solenoid valve working stably. It avoids control failure caused by contamination. This isolation function meets the operational standards of Sealed Diaphragm Pump and Sealing Elements for Valves in industrial settings that have a lot of dust or are humid.

2. Required Characteristics

1)Ultra-Precision Adaptability:It has extremely small dimensional tolerances. Usually, this tolerance is within ±0.05mm. Its shape matches the solenoid valve’s sealing cavity perfectly. If there’s any mismatch, installation gaps will form easily. These gaps can lead to leakage. Leakage will affect the stability of the production line. This precision is the same as the manufacturing standards of Pressure Seal Components for industrial automation.

2)Resistance to Extreme Working Conditions

a)Temperature Resistance:It can stand common industrial temperature ranges. Like from -40℃ to 150℃, or even higher. For example, solenoid valves used for high-temperature steam need to stand temperatures above 120℃. Solenoid valves in low-temperature cold chain equipment need to stand temperatures below -30℃. This ability to handle different temperatures meets the environmental adaptability of Fluid-Tight Diaphragms in diverse industrial scenarios.

b)Pressure Resistance:It can stand the fluid pressures in production lines. For example, in hydraulic systems, the pressure can be up to dozens of MPa. In pneumatic systems, it’s usually 0.4–1.6MPa. Even under these pressures, the gasket won’t crack or change shape. This pressure capacity matches the performance requirements of gaskets used with Sealed Fluid Direction Control Valve.

c)Corrosion Resistance:It can stand erosion from media in production lines. Like acid-alkali liquids in chemical lines, or corrosive cleaning agents in food lines. Common materials used for this gasket are corrosion-resistant ones. Like fluoroelastomer (FKM) and perfluoroelastomer (FFKM). This meets the material standards of Gasket & Membrane Assemblies in harsh chemical environments.

d)High Elastic Memory:The solenoid valve opens and closes very often. This causes the gasket to be compressed and deformed for a long time. Even so, the gasket can still bounce back to its original shape quickly. It keeps providing the force needed for sealing. This avoids leakage caused by losing elasticity. This elastic performance is as good as that of high-quality Diaphragms & Sealing Gaskets used in dynamic sealing applications.
