This valve features high-precision machining and enhanced stem sealing to withstand negative pressure. It operates with a standard quarter-turn handle but provides the tightness required for low-to-medium vacuum ranges. It is the gatekeeper for vacuum pumps and chambers.<\/p>\n<h2 data-path-to-node=\"21\">\u4e3b\u8981\u6280\u8853\u4ed5\u69d8<\/h2>\n<ul data-path-to-node=\"22\">\n<li>\n<p data-path-to-node=\"22,0,0\"><b>\u30dc\u30c7\u30a3\u7d20\u6750\uff1a<\/b> ASTM 316\u30b9\u30c6\u30f3\u30ec\u30b9\u92fc<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"22,1,0\"><b>\u30b5\u30a4\u30ba\u7bc4\u56f2\uff1a<\/b> 1\/2\u2033 ~ 2-1\/2\u2033<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"22,2,0\"><b>Pressure Range:<\/b> Suitable for High Vacuum \/ Negative Pressure<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"22,3,0\"><b>\u30b7\u30fc\u30ea\u30f3\u30b0\uff1a<\/b> Specialized Vacuum-Rated Packing<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"22,4,0\"><b>\u30aa\u30da\u30ec\u30fc\u30b7\u30e7\u30f3<\/b> \u624b\u52d5\u30cf\u30f3\u30c9\u30eb<\/p>\n<\/li>\n<\/ul>\n<h2 data-path-to-node=\"23\">\u5229\u70b9\u3068\u30e1\u30ea\u30c3\u30c8<\/h2>\n<ul data-path-to-node=\"24\">\n<li>\n<p data-path-to-node=\"24,0,0\"><b>Vacuum Integrity:<\/b> Designed to prevent atmospheric air from leaking into the system.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"24,1,0\"><b>High Conductance:<\/b> Straight-through flow path minimizes pumping time (high flow conductance).<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"24,2,0\"><b>\u8010\u4e45\u6027\u304c\u3042\u308b\uff1a<\/b> 316SS construction ensures low outgassing and corrosion resistance.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"24,3,0\"><b>Reliability:<\/b> Simple, robust design requiring minimal maintenance.<\/p>\n<\/li>\n<\/ul>\n<h2 data-path-to-node=\"25\">\u9069\u7528\u5206\u91ce\u3068\u8a2d\u7f6e\u5834\u6240<\/h2>\n<ul data-path-to-node=\"26\">\n<li>\n<p data-path-to-node=\"26,0,0\"><b>Vacuum Packaging:<\/b> Chamber isolation.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"26,1,0\"><b>Laboratories:<\/b> Vacuum drying and filtration setups.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"26,2,0\"><b>Semiconductor:<\/b> Roughing lines for vacuum pumps.<\/p>\n<\/li>\n<li>\n<p data-path-to-node=\"26,3,0\"><b>\u5de5\u696d\u88fd\u9020\u696d\uff1a<\/b> Vacuum chucking and holding systems.<\/p>\n<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p data-path-to-node=\"17\"><b>High-Integrity Sealing for Negative Pressure Environments.<\/b><\/p>\n<p data-path-to-node=\"18\">\u305d\u306e <b>\u624b\u52d5\u771f\u7a7a\u30d0\u30eb\u30d6<\/b> is a specialized ball valve designed to hold a vacuum without leakage.
