Product description
ZZYP self regulating valve is a kind of without external driving energy, by adjusting the pressure of the medium itself as the power source and the medium pressure changes, according to the predetermined set values, automatic adjustment of the energy saving control device. It sets the detection, control, perform many functions in a valve, self-contained instrument control system.

- Valve maintenance
1 before installation should be carefully check valve nameplate content, to ensure that the valve type, size, seat materials, temperature rated values in line with the use of pipeline.
2 remove the protective cover on both sides of the flange, the valve is fully open in the state to wash clean.
3 prepare and remove the remaining impurities in the clean piping (which may damage the valve seat and ball) before connecting the pipe to the pipe.
4 during the installation, please do not use the valve body part as a lifting point, to avoid damage to the actuator and accessories. .
5 this type of valve should be installed in the horizontal direction or vertical direction of the pipe.
6. Install the pipeline near the falls, or to withstand external force phenomenon, can use pipe support or supports pipeline to eliminate the deviation.
7 after connecting with the pipe, use the specified torque cross locking flange connection bolt.
