KD7T42/3P spring type quick closing butterfly valve in the gas waste heat power generation system and the extraction steam heating turbine system, this kind of valve as a system safety guarantee, has been increasingly widely used. It can be used to replace the electric stop valve and check valve in the original system design because of its fast closing, flow resistance, sealing cut-off and other excellent properties. The products are mainly used in parallel units of thermal power plants and gas waste heat generating units, as an emergency cut-off valve to protect the safety of the system.

Product Overview
KD7T42/3P spring type quick closing butterfly valve in the gas waste heat power generation system and the extraction steam heating turbine system, this kind of valve as a system safety guarantee, has been increasingly widely used. It can be used to replace the electric stop valve and check valve in the original system design because of its fast closing, flow resistance, sealing cut-off and other excellent properties. The products are mainly used in parallel units of thermal power plants and gas waste heat generating units, as an emergency cut-off valve to protect the safety of the system.
Structural characteristics
1. The fast closing time can reach 0.5 seconds, and the emergency cutting is safe and reliable;
2, three eccentric metal dense, sealing structure opening and closing light and flexible, sealing zero leakage;
3, room temperature medium can choose double eccentric soft seal structure, low cost, reliable seal;
4, close the valve end buffer, effectively avoid the valve inertia impact;
5, can use the spring to achieve fast close, liquid can use the accumulator to achieve fast close, the two forms of work in the same way, the same safe and reliable.
