Standard TestBody Test: 1.5 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.
The main advantages of pneumatic butterfly valves:
1. Small and lightweight, easy disassembly and maintenance. They can be installed in any position.2. Simple and compact structure. Small operating torque. Quick 90 degrees rotating opening.3. The flow characteristics are of a straight line. The regulating performance is good.4. The connection between butterfly plate and valve stem uses the no-pin structure, overcoming the possibility of any internal leakage point.5. The outer sphere of the butterfly valve uses spherical shape, improving the sealing performance and prolonging the valve’s service life. Opening and closing under pressure more than 50000 times still remains zero leakage.6. The sealing item can be replaced. The sealing is so reliable that two-way sealing can be achieved.7. According to user requirements, the butterfly plates can be sprayed coating, such as nylon or PTFE.8. Pneumatic butterfly valves can be design into flange connection and clip connection.9. The driving method can include manual, electric or pneumatic.
