The pressure balanced grease injection plug valve is suitable for controlling the flow of medium on the petroleum, chemical, natural gas and other working conditions pipelines with pressure level of Class150~2500, PN10~PN420 and working temperature of -46~180°C.
1. Cast steel valve body, pressure balanced type, flip plug structure, grease injection seal;
2. The valve body cavity and as the sealing surface are precision machined, ground and hand-ground;
3. The surface of the seal is treated with a special anti-friction/high anti-wear coating;
4. When the product needs to be buried, the valve stem extension device can be provided, and the grease injection device and auxiliary structure are also extended through the built-in pipeline;
5. Locking devices can be provided at the flag position and closing position;
6. According to IS05211 standards, the drive device is connected to the interface, pneumatic, electric, gas-liquid linkage and other driving modes for users to choose.
