Body Test: .5 times the working pressure with water. This test is performed after valve assembly and with disc in half position open, it is called as a body hydro test.
Seat Test: 1.1 times the working pressure with water.
Function / Operation Test: At the time of final inspection, each valve and its actuator (Flow-Control Lever / Gear / Pneumatic Actuator), under goes a complete operating test (Open/Close). This test carried out without pressure and at ambient temperature. It ensures the correct operation of the valve / actuator assembly with accessories such as solenoid valve, limit switches, air filter regulator etc.
Special Test: On request, any other test can be carried out according to special instruction by client.
Product advantages
- Simple structures.Easier to be manufactured and repaired.
- Small working stroke,short opening and closing time.
- Good sealing performance,small friction between sealing face and life long.
- The friction between sealing face is smaller than gate valve during the process of opening and closing.And it’s wear-resistant.
- It usually have only one sealing face,good manufacturing process and easy to be repaired.
- The structure style of globe valve’s body can be divided into straight-through, three-and right-angle type.
