SKU: Flange Butterfly Valve 2 Category: Tag:

1.Parameter Information:

Manual Flange Butterfly Valve

2.Product advantages:

1、The length of the short structure can save raw materials and installation space, and also effectively support the strength of the pipeline

2、The valve block is the correct movement of the gate, extrusion fast, to ensure the effective sealing valve

3、Triangle support material, guarantee the required mechanical properties

4、According to different working conditions demand design V, triangle, or five corners and other ports, in order to meet the needs of various flow regulation

5、No groove at the bottom to make sure no slag and full bore flow

3.Standard test:

Body Test: 1.5 times the working pressure with water. This test is performed after valve assembly and with the disc in half position open, it is called 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), undergoes 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 the client.
