This is a diaphragm pump rubber valve plate. It’s made just for micro-fluid systems or precision fluid valves. It uses its high-precision structural design and high-quality sealing materials. Because of these, it has become a key part in the fluid control process. Its main function is focused on two things: precise one-way control of fluids and reliable sealing. When it’s working, it can open and close the valve by itself. It does this based on the fluid pressure difference in the system. This lets fluid flow stably only in the single direction that’s set in advance. At the same time, it strictly stops fluid from flowing backward. This stops fluid backflow from causing interference to the system or damaging it. So it gives stable and accurate control support for miniaturized and high-precision fluid transmission scenarios.
Product Features:
1、Excellent Reverse Sealing Performance: Reverse sealing is the main function of a one-way valve. In precision instruments or small equipment, even small dimensional deviations might make the rubber valve plate work badly. This check valve uses its precise dimensional control. This makes sure the sealing surfaces of the valve core and valve seat match with high precision. When there’s reverse pressure, it fits tightly with the valve seat. This makes sure it seals well and stops fluid from leaking backward. This is very important for the reliability of Mini Sealed Valve applications.
2、Smooth Forward Flow Capacity: The minimum forward pressure needed to open the valve core matches what the environment requires. It shouldn’t be too high—because that would slow down fluid flow. It also shouldn’t be too low—because then vibration or impact might open it by accident. The one-way valve made by the DOIT brand has a smooth internal flow channel design. There are no right angles or bumps inside. The valve core has a smooth shape, and its thickness is just right. This reduces fluid resistance and makes sure fluid flows forward smoothly. So it’s suitable for Sealed Fluid Direction Control Valve setups.
3、Superior Wear Resistance: The valve core and valve seat are opened and closed many times. This easily causes wear. At the same time, the valve disc has to handle the impact and friction from high-speed, high-pressure fluids. This is to lower the risk of failure. This one-way valve can be chosen based on what the environment needs. It can go through thousands to tens of thousands of opening and closing cycles. And it won’t have big wear or fatigue failure. This meets customers’ needs for how long the one-way valve can be used. It works well for Micro Sealed Hydraulic Pump systems.
4、Good Flexibility and Elasticity: One-way valves need to control the direction of fluid flow often. They do this by opening and closing. These movements are done by using the impact force of fluids on elastic rubber. Forward impact makes it open, and reverse impact makes it close. So there are high requirements for the material’s elasticity. If elasticity is too high, it’s not good for controlling flow rate. If elasticity is too low, it slows down flow rate. So it’s necessary to pick elastic rubber materials that match what the environment needs. This makes sure it works best in Sealed Diaphragm Pump applications.
5、Corrosion Resistance: Some application scenarios involve contact with different chemical media. For these, the one-way valve disc needs to resist being worn away by chemical substances. This one-way valve is made of materials that are very good at resisting corrosion. This makes sure the product lasts a long time. So it can be used in Sealed Fluid Transfer Pump systems. And it works with Seals for Gaskets and Grommet.
