Valve Handwheels For Industrial Valve Design Requirements

Last year, the standard of industrial valve plunger valve was officially released, and it provided comprehensive and detailed standards for its materials, inspection methods, packaging, transportation and storage. Therefore, in response to the new standard, the valve handwheel quickly synchronized its suitable size material.

The standard for valve handwheel synchronization is based on its nominal pressure, material temperature, and housing strength. These are designed in-house through experimental verification. The new provisions of its industrial valve nominal size from DN-DN400, iron valve material pressure - temperature rating according to GB/T17241.7 requirements; steel valve material pressure - temperature rating according to GB/T12224 requirements Sealing performance should be in accordance with Class A of GB/T 13927-2008, so our carbon steel handwheels, steel pipe welding handwheels, and iron pipe welding handwheels should be handled according to their supporting performance. In addition, the plunger valve shell strength test according to the provisions of GB/T13927-2008; plunger valve sealing performance test according to the provisions of GB/T13927-2008; plunger valve static life test according to JB/T8859 It is stipulated that after the static pressure life test, the shell strength and sealing performance test shall be carried out, and the test results shall meet the requirements of 4.2.1 and 4.2.2.

Industrial valve This standard applies to nominal pressure PN10 ~ PN40, nominal size DN15 ~ DN400, working temperature 0 ~ 300 °C, the working medium for steam, gas, oil and other non-corrosive media. These are the technical standards for valve handwheels.
