Plastic UPVC ball valveKey points of construction and installation

1) The installation position, height, and import/export direction must meet the design requirements, and the connection should be firm and tight.

2) All types of manual valves installed on insulated pipelines must not have handles facing downwards.

3) Before installing the valve, a visual inspection must be conducted, and the valve nameplate should comply with the current national standard "General Valve Marking" GB 12220. For valves with a working pressure greater than 1.0 MPa and a shut-off function on the main pipeline, strength and tightness tests should be conducted before installation, and they can only be used after passing the tests. During the strength test, the test pressure shall be 1.5 times the nominal pressure, and the duration shall not be less than 5 minutes. The valve shell and packing shall be qualified if there is no leakage. During the tightness test, the test pressure is 1.1 times the nominal pressure; The test pressure should meet the requirements of GB 50243 standard for the duration of the test, and it is considered qualified if there is no leakage on the sealing surface of the valve disc.

4) Install a sealing gasket between the valve flange and the pipeline flange according to the pipeline design requirements.

5) Ball valves with transmission mechanisms should be installed according to the instructions in the product manual
