This device mounts to the valve stem and converts multiple turns of the handwheel into a slow, powerful 90-degree rotation of the ball. This mechanism is enclosed in a weather-resistant housing, making it suitable for outdoor use.<\/p>\n<h2 data-path-to-node=\"8\">\u4e3b\u8981\u6280\u8853\u898f\u683c<\/h2>\n<ul data-path-to-node=\"9\">\n<li>\n<p data-path-to-node=\"9,0,0\"><b>Mechanism:<\/b> Worm Gear Reduction<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"9,1,0\"><b>\u64cd\u4f5c\uff1a<\/b> Multi-turn Handwheel<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"9,2,0\"><b>Housing Material:<\/b> Cast Iron \/ Painted Steel (Weatherproof)<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"9,3,0\"><b>\u76f8\u5bb9\u6027\uff1a<\/b> ISO 5211 Mount Pads<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"9,4,0\"><b>\u529f\u80fd\uff1a<\/b> Self-locking (valve stays in position)<\/p>\n<\/li>\n<\/ul>\n<h2 data-path-to-node=\"10\">\u512a\u52e2\u8207\u597d\u8655<\/h2>\n<ul data-path-to-node=\"11\">\n<li>\n<p data-path-to-node=\"11,0,0\"><b>\u5b89\u5168\uff1a<\/b> Prevents the handle from snapping back due to line pressure, protecting the operator.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"11,1,0\"><b>Ease of Use:<\/b> Reduces the physical force needed to operate large valves by up to 80%.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"11,2,0\"><b>Water Hammer Prevention:<\/b> The slow opening\/closing speed prevents sudden pressure surges in the pipeline.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"11,3,0\"><b>Fine Adjustment:<\/b> Allows for more precise positioning than a lever handle.<\/p>\n<\/li>\n<\/ul>\n<h2 data-path-to-node=\"12\">\u61c9\u7528\u9818\u57df\u8207\u4f4d\u7f6e<\/h2>\n<ul data-path-to-node=\"13\">\n<li>\n<p data-path-to-node=\"13,0,0\"><b>Main Utility Lines:<\/b> Large water or steam headers (4&#8243; and above).<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"13,1,0\"><b>High-Pressure Systems:<\/b> Where line pressure makes lever operation impossible.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"13,2,0\"><b>Confined Spaces:<\/b> Where there is no room to swing a long lever handle.<\/p>\n<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p data-path-to-node=\"4\"><b>Effortless Control for Large or High-Pressure Valves.<\/b><\/p>\n<p data-path-to-node=\"5\">\u7684 <b>\u624b\u8f2a\u88dd\u7f6e<\/b>, also known as a <b>Gear Operator<\/b>, is designed to replace standard lever handles on larger ball valves.
