Ceramic Gate Valve

I. Standard:
1. Design and Manufacture: API 600
2. Face to face: ISO5752
3. Pressure and Temperature acc: ISO 7005
4. Test acc: ISO 5208

II. Purpose
Ceramic gate valve is applied to the tubes of petroleum, chemical, mine and electric power industries whose pressure from PN1.6 to 10.0Mpa and the temperature is -29~540 centigrade. It can cut off and turn on the medium. It can improve service period more than 10 multiple than general alloy sealing especially in alumina, scum and mushy stage system.
