The Expanding Slab Gate Valve Structural Details And Features
The double slab gate valve is a novel structured slab gate valve product. It has the characteristics of small opening and closing torque, fast speed, small vibration, long service life, safe and reliable operation, etc. It is mainly used for natural gas extraction and long-distance pipeline purification.
The parts of the valve sealing mechanism are separated from each other, and the seal can still be ensured even if deformation is caused when the temperature changes, and the gate will not be squeezed and cannot be opened due to high temperature expansion.
The valve seal is made of wear-resistant and corrosion-resistant materials, which prolongs the service life of the valve. In the case of high temperature and high pressure, the gate on the inlet side is designed as a pressure relief method to prevent abnormal pressure increase in the cavity caused by temperature changes and ensure safe use. Fully enclosed structure, good protection performance, can be used all-weather.
