APPLICABLE RANGE
This series of valves are applicable in fields of petroleum, chemical industry, metallurgy, steel, electric power, light spinning, paper making, sewage treatment etc, and also applicable for low pressure pipes, It can transport all kinds of eroded particles and gas medium under normal temperature and middle temperature, stop current, and adjust flux, without medium affect.
PERFORMANCES AND CHARACTERISTICS
1. Reliable seal. drive the valve spindle 90?clockwise starting the full open position, the dirt on seal surface will be cleaned by itself, so that the seal effect, if a small angle is closed, it can be sealed more closely, and the seal clearance appeared for a long time can also be get rid of ,therefore, the seal reliability can be ensured.
2. corrosion and wear resistant and long service life, when starting drive the valve spindle for a small angle anticlockwise, the seal can be departed, so that wear is small ,and through heat treatment on he seal place ,so that it is wear resistant ,for different medium, different applicable seal material can be chosen, and the requirement of wear and corrosion resistant can be reached.
