صمام فحص مزدوج اللوحة بمقعد مطاطي

The rubber seat dual plate check valve is widely used in water supply, HVAC, and industrial piping systems for its compact structure, reliable sealing, and low pressure loss. Featuring a dual-plate swing design, it allows fluid to flow freely in one direction while preventing backflow automatically, using spring-assisted plates that close quickly when flow reverses. The rubber seat provides a soft, resilient sealing surface that ensures bubble-tight shut-off, reduces noise, and minimizes water hammer. This type of valve is especially effective in systems with fluctuating flow and moderate pressures. Its lightweight and wafer-style body makes it easy to install between flanges, even in space-limited applications. The low cracking pressure and minimal maintenance needs further enhance its operational efficiency. Ideal for use in clean water, wastewater, and non-corrosive liquids, this valve offers a cost-effective and dependable solution for backflow prevention.
