【Structural characteristics of high-pressure balanced globe valve】

1The valve disc does not have a through-hole, and the medium flows into the valve chamber from the valve disc to balance the medium received by the valve disc, resulting in a small opening and closing torque.
2The lifting valve stem structure is easy to open and has good sealing performance.
3adoptF-4Composite rubber sealing ring, with good sealing performance and resistance to acid and alkali corrosion

【Precautions for installation of high-pressure balanced globe valve】

1) The installation position, height, and import/export direction must meet the design requirements, and the connection should be firm and tight.
2) Various types installed on insulated pipelinesmanual valveThe handle must not be lowered.
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.
