Axial operating force of plug valve

The axial operating force of the plug valve should be less than 15N.

The axial operating force of the oven shut-off valve should be less than 25N, and the axial operating force of the external embedded stove shut-off valve should be less than 45N (to ensure that the solenoid valve can be closed).The main plug valve product names of China Plug Valve Network include:ANSI Plug Valve,ANSI Worm Gear Plug Valve,,ANSI Flange-connection Hard-sealed Lift Plug Valve,ANSI Sleeve Soft-sealed Plug Valve,ANSI Pessure Balanced-type Inverted Oil-sealing Plug Valve,Flange-connection Two-way Plug Valve

The shut-off valve should be able to withstand an axial pressure of 100N for 1 minute. After repeated 5 times, the solenoid valve should not be damaged or deformed, and its electrical and air tightness performance should meet the standard requirements.

Axis stability and stroke

The shaft and valve seat should be tightly matched, and the circumferential eccentricity should be less than; The maximum axial stroke of the valve is ≤ 4mm.

Oil resistance of rubber sealing gasket

After soaking in n-pentane liquid for 72 hours, take it out and place it in air for 24 hours. The mass change rate should be less than 20%, and there should be no brittleness, softening, or expansion that hinders use; Reinstall the valve body and test the airtightness of the plug valve assembly, which should meet the requirements.

M-mass change rate, M-post experiment mass, M0 pre experiment mass.
