Operating torque of plug valve

The measured operating torque of a plug valve assembly without a piezoelectric ignition device should be less than N · m at room temperature, and the operating torque should be less than N · m at a high temperature of 150 ℃± 5 ℃ (immediately tested after being left for 15 minutes).The main plug valve product names of China Plug Valve Network include:Orbit Plug Valve,Pressure-gauge Plug Valve,Single(double) Flush Plug Valve,T-model Three-way Plug Valve,T-model Three-way Stainless Steel or Cast Steel Plug Valve,Two-way Heat-preservation Plug Valve

The measured operating torque of the plug valve assembly with piezoelectric ignition device should be less than N · m.

Strength of limit device: When the plug valve assembly is fully open, it should be subjected to 10 times of 1 N · m torque (for 10 seconds), and the limit device should be checked for deformation and damage.

Strength of self-locking device: When the plug valve assembly is in the closed position, the external embedded stove valve needs to receive 10 times of 1 N · m torque (for 10 seconds), and the oven valve needs to apply 5 times the measured operating torque. During the torque application process, it should not unlock and the self-locking device should not fail.
