Bolted Bonnet Gate Valve
204 products found
A bolted bonnet gate valve is a heavy-duty, linear-motion isolation valve featuring a removable top cover (bonnet) securely bolted to the valve body’s upper flange with an integrated sealing gasket. This robust, pressure-retaining construction is designed to withstand high-torque and high-pressure industrial environments while providing maintenance technicians with easy, direct access to internal components like the stem, wedge, and seat rings for inline servicing. Engineered in accordance with API 600 or API 602 standards, these valves utilize a fully guided wedge (solid, flexible, or split design) that moves perpendicular to the fluid path to deliver a reliable, leakproof shutoff with minimal seat scuffing and erosion. When you work with us, you're tapping into a network of experienced China gate valve manufacturers. We cast and forge our bolted bonnet gate valves from superior-strength carbon steel, stainless steel, and alloy materials, and equip them with live-loaded stem packing and hard-faced seats—so you get long-term, reliable operation without the hassle.
