Duplex Steel Pressure Seal Gate Valve
Product Information
The duplex stainless steel pressure seal gate valve is an advanced technological product that boasts unparalleled sealing performance with zero leakage. It is equipped with an inclined elliptical butterfly plate with a radial dynamic balance sealing system that ensures reliable and efficient sealing. This valve is a cutting-edge four-eccentric two-way sealing butterfly valve, composed of a valve body, valve plate, valve rod, and sealing ring. The valve plate is easily mounted in the valve body, while the valve rod is rotated in the valve body shaft hole. The valve plate and valve rod are secured via pins, facilitating their synchronous rotation. The valve's exceptional construction guarantees a high-level performance in various applications.
Features
The pressure seal gate valve made of duplex stainless steel boasts excellent features including a compact structure, a well-designed construct, optimal valve rigidity, smooth channeling, and a low flow coefficient. Its sealing surface is expertly crafted with stainless steel or hard alloy, promising exceptional longevity. To ensure reliable sealing and facilitate flexible operation, this gate valve is equipped with flexible graphite packing.
