Product advantages:
1. This product can be equipped with electronic control integrated system to achieve dual-use electrical control and remote control, more safe and flexible!
2. The valve core is equipped with chrome plating treatment, which greatly improves the surface hardness and wear resistance of the valve core.
3. The valve body is made of vermicular graphite cast iron RT450 material, with high wear resistance, high temperature and high pressure resistance. Even in high temperature and high pressure environment can work stably, the valve hole is not easy to deform.
4. The rubber ring is made of fluorine rubber material, which is resistant to high temperature and chemical corrosion, and has good aging resistance and high pressure resistance, and the permeability is also very low, even under very harsh working conditions
Still has very good wear resistance.
5. Safety relief valve after strict pressure test, accurate opening and closing, with lead seal does not allow private pressure regulation.
