Manual Needle Valve
Manual needle valves are engineered for high & ultra-high pressure fluid control, including standard needle valves, ferrule-type needle valves, precision throttle valves and high-low temperature resistant needle valves. Made of 316 stainless steel and premium alloy materials, they feature excellent pressure resistance, corrosion resistance and sealing performance. With diversified structures and specifications, the full series covers common pressure grades and extreme temperature working conditions, widely used for on-off and flow regulation of liquid, gas and corrosive media in industrial fields.
Core Advantage
Application
Ultra-high pressure test equipment, petroleum & petrochemical industry, natural gas exploitation, laboratory fluid control, instrument gas & liquid pipelines, LNG & air separation industry, power plant & steam system, fine chemical reaction, water jet equipment etc.
