Service

The company provides valve applications for power plants. Gate valves can be divided into mode gate valves and parallel gate valves according to the sealing surface configuration. Mode gate valves can be divided into single gate valves, double gate valves and flexible gate valves.  Parallel gate gate valves can be divided into single gate and double gate.  It can also be made into a gate that can produce slight deformation to improve its technology and compensate for the deviation of sealing face Angle in the process of processing. This gate is called elastic brake.  

A gate valve consists of a gate valve body and a gate, and the gate has two sealing faces. The two sealing faces of the common mode gate valve form a wedge, and the wedge Angle varies with the valve parameters. The mode gate type gate valve is a wedge.  The gate of a mode gate valve can be made into a single piece, called a rigid gate;  It can also be made into a gate that can produce slight deformation in order to improve its technology and make up for the deviation of sealing face Angle in the process of processing. This gate is called elastic brake.  

Open stem gate valve stem head in the opening and closing of the valve will lift, that is, can see the stem movement (not rotating only lift), the so-called dark stem gate valve stem in the opening and closing of the valve will only rotate and not lift.
