The gate has a rigid gate and an elastic gate. According to the difference of the gate, the gate valve is divided into a rigid gate valve and an elastic gate valve.<\/p>\"\n }\n <\/script><script src=\"https:\/\/www.covna-china.com\/assets\/js\/common.js\"><\/script><script src=\"https:\/\/cdn.staticfile.org\/tiny-slider\/2.9.3\/tiny-slider.js\"><\/script><script src=\"https:\/\/cdn.jsdelivr.net\/npm\/just-validate@1.5.0\/dist\/js\/just-validate.min.js\"><\/script><script>\n ! function() {\n var e = document.querySelector(\"[digood-page-content]\"),\n t = document.querySelector(\".cd-top\"),\n o = document.querySelector(\"#header\"),\n n = document.querySelector('iframe[loading=\"lazy\"]'),\n r = !1;\n if (t.onclick = function(t) {\n t.preventDefault(), e.scrollTo({\n top: 0,\n behavior: \"smooth\"\n })\n }, e.onscroll = function() {\n if (e.scrollTop > 300) {\n if (t && t.classList.add(\"cd-is-visible\"), o && o.classList.add(\"fixed\"), !r) {\n const e = n.getAttribute(\"data-src\");\n n.setAttribute(\"src\", e), r = !0\n }\n } else t && t.classList.remove(\"cd-is-visible\", \"cd-fade-out\"), o && o.classList.remove(\"fixed\");\n e.scrollTop > 1200 && t.classList.add(\"cd-fade-out\")\n }, $btn_scroll = document.querySelectorAll(\"._btn-scroll_1k55i_778\"), $btn_scroll.length && $btn_scroll.forEach((function(e) {\n e.onclick = function(t) {\n t.preventDefault();\n const o = e.getAttribute(\"href\"),\n n = document.querySelector(o);\n n && n.scrollIntoView({\n behavior: \"smooth\"\n }), gtag(\"event\", \"conversion\", {\n send_to: \"AW-343726230\/\",\n url: window.location.href,\n button: e.getAttribute(\"name\")\n })\n }\n })), document.querySelectorAll(\".slider-reviews\").length) {\n tns({\n container: \".slider-reviews\",\n items: 1,\n mouseDrag: !0,\n controls: !1,\n navPosition: \"bottom\",\n autoHeight: !0,\n responsive: {\n 992: {\n gutter: 30,\n items: 2\n }\n }\n })\n }\n if (document.querySelectorAll(\".slider-features\").length) {\n tns({\n container: \".slider-features\",\n items: 1,\n mouseDrag: !0,\n controls: !1,\n navPosition: \"bottom\",\n autoHeight: !0,\n gutter: 15,\n responsive: {\n 768: {\n items: 2\n },\n 992: {\n items: 3\n },\n 1200: {\n items: 4\n }\n }\n })\n }\n new window.JustValidate(\"._contact-form_1k55i_777\", {\n rules: {\n message: {\n required: !0,\n minLength: 5,\n maxLength: 2e3\n }\n }\n }), document.addEventListener(\"DOMContentLoaded\", (function(e) {\n var t = document.querySelectorAll('[data-toggle=\"faq_collapse\"]');\n t.length && t.forEach((function(e, t) {\n e.onclick = function(e) {\n e.preventDefault();\n const t = this.getAttribute(\"href\"),\n o = document.querySelector(t);\n o ?
