Structural Features:
1. Solid forged valve body and valve elements;
2. Valve seat and gate sealing surface made by automatic surfacing welding of cobalt-based cemented carbide by plasma spray welding machine. The hardness of sealing surface is uniformly around HRC 40-45, which can meet the high temperature and high pressure working conditions below 650 °C. It has high wear-resistant, corrosion resistance, scratch resistance and long service life;
3. Optional elastic single wedge gate, double wedge gate, parallel double gate is designed to meet the requirements of various working conditions;
4. Stem has surface hardening and anti-corrosion treatment. It can be easily operated with reliable sealings;
5. Corrosion-inhibiting, metal composite packing is used under special conditions to ensure no leakage;
6. Perfectly worked with various domestic and imported brand electrical actuators to meet DCS control requirements.
