Elastic Seat Gate Valve DN50-DN300 ductile cast iron PN16 resilient seat hand wheel double epoxy coating flanged gate valve

product description

The types of gate valves can be divided into wedge gate valves and parallel gate valves according to the sealing surface configuration. Wedge gate valves can be divided into: single gate type, double gate type and elastic gate type; parallel gate valves can be divided It is single ram type and double ram type. According to the thread position of the valve stem, it can be divided into two types: rising stem gate valve and dark stem gate valve.

Advantage
1. Small flow resistance. The medium channel inside the valve body is straight through, the medium flows in a straight line, and the flow resistance is small.
2. It is less labor-saving when opening and closing. Compared with the globe valve, because whether it is open or closed, the direction of movement of the gate is perpendicular to the direction of medium flow.
3. Large height and long opening and closing time. The opening and closing stroke of the gate is relatively large, and the lowering is carried out by the screw.
4. The phenomenon of water hammer is not easy to occur. The reason is the long shutdown time.
5. The medium can flow in any direction on both sides, which is easy to install. The two sides of the gate valve channel are symmetrical.
6. The structural length (the distance between the two connecting end faces of the housing) is relatively small.
