شیر پروانه‌ای استاندارد با دو افست و نشیمنگاه لاستیکی

The standard double offset butterfly valve rubber seated is designed to provide tight shut-off with reduced seat wear, making it ideal for industrial systems that require reliable flow control and frequent operation. The “double offset” refers to the disc being offset from the valve centerline in two directions, which minimizes contact between the disc and the seat during opening and closing. This design significantly extends the valve's service life and reduces operating torque. The rubber seat ensures bubble-tight sealing, making it suitable for water, air, and non-corrosive fluid applications. Commonly used in water treatment plants, power generation, and district heating systems, this valve offers a good balance of durability, sealing performance, and ease of operation. Its quarter-turn function allows quick shutoff, and the design supports both manual and automated actuation. This valve is especially preferred in systems where low maintenance and high reliability are key requirements.
