Copper sealed gate valve is a type of valve that uses copper or copper alloy as the core sealing material, and achieves reliable closure through a metal to metal hard sealing structure. It is specifically designed for corrosive media or high temperature and high pressure environments. Its characteristics include:

Material characteristics: The sealing surface is made of copper alloy, which is resistant to oxidation, acid and alkali corrosion, and suitable for water, steam, oil and weakly corrosive gases;

Structural design: Bidirectional elastic seal or wedge-shaped gate design, ensuring tight fit under high pressure and low leakage rate;

Application scenarios: Commonly used in chemical pipelines, HVAC systems, water supply and drainage, and gas transportation, with a temperature tolerance of up to 250 ℃ and a pressure of ≤ 6.4MPa;

Core advantages: Reliable sealing, erosion resistance, easy maintenance, significantly longer service life than ordinary soft sealed valves.
