Light weight: The body is made of high-grade nodular black cast iron, and the weight is about 20%~30% less than the weight of the traditional gate valve. The equipment is easy to repair.
Flat-bottomed gate seat: The traditional gate valve usually deposits in the groove at the bottom of the valve due to foreign objects such as stones, wood, cement, iron filings, sundries, etc. after the pipe is flushed with water. The bottom of the elastic seat-sealed gate valve adopts the same flat-bottom design as the water pipe, which is not easy to form debris and makes the fluid flow in all directions.
Overall encapsulation: High-quality rubber is used for the overall internal and external rubberization of the ram. European first-class rubber vulcanization technology enables the vulcanized ram to ensure accurate several dimensions, and the rubber and ductile ram are connected reliably and not easy to fall. And good memory of flexibility.
Precision-cast valve body: The valve body is precision forged, and the precise dimensions make the inside of the valve body without any finishing to ensure the sealing of the valve.
Pneumatic flange gate valve gate valve advantages
1. The fluid resistance is small, and the sealing surface is less brushed and corroded by the medium.
2. It saves effort to open and close.
3, the flow direction of the medium is not restricted, does not disturb the flow, and does not reduce the pressure.
4. The shape is simple, the structure is short, the production technology is good, and the scope of application is wide.
Pneumatic flange gate valve gate valve defects
1. It is easy to cause erosion and scratches between the sealing surfaces, and it is difficult to repair.
2. The size of the appearance is large, opening the space with a certain demand, and the opening and closing time is long.
3. The structure is messy.
Pneumatic flange gate valve varieties
According to the sealing surface configuration, it can be divided into wedge gate valve and parallel gate valve. Wedge gate valve can be divided into: single gate, double gate and elastic gate; parallel gate valve can be divided into single gate Plate type and double gate type. According to the thread position of the valve stem, it can be divided into two types: the open-stem gate valve and the concealed-stem gate valve.
