Insulated fully welded ball valves is produced by our company directly buried type and a full welded ball valve, with insulation can be buried underground extension rod can be customized, and valves can be insulated to prevent some after freezing or curing medium valves, heat preservation form can set the system, the medium mass flux through insulation type full welded ball valve is not affected by temperature, can make a steady flow of medium through the valve.The valve is mainly used in buried or heat preservation working conditions such as natural gas pipeline and heat supply network.
1. Adopt integrated structure and heat preservation process to ensure the safety and reliability of the valve;
2. The tubular structure is used for simple manufacturing process and convenient processing;
3. The machining precision of the sphere is very precise and easy to operate, and the stainless steel or solid ball can be customized according to customers' requirements;
4. Insulated all-welded ball valves can be customized according to customer requirements. Customers can provide drawings for processing according to customer drawings;
5. The valve seat is composed of PTFE sealing ring and spring spring, which has strong adaptability to pressure and temperature changes, and will not cause any leakage within the service range, which is very safe;
6, thermal insulation type all-welded ball valve in normal operation, the body covered with corrosion resistant leach or epoxy resin, in buried working conditions, strong adaptability, and with insulation to adapt to more media.
