Strengthen on-site fire prevention with electrostatic discharge-treated piping components! Are you overlooking any threaded connections? 【Is an anti-static valve necessary?】 When using a ball valve, static electricity is generated due to the friction between the fluid and the metal ball valve. In fluids with low conductivity (such as oil), static electricity accumulates inside the ball. If there is no mechanism to discharge the static electricity from the ball to the outside of the valve, the accumulated static electricity can create sparks, igniting flammable fluids and leading to a fire. Measures are necessary when flowing low-conductivity and flammable fluids (e.g., petroleum). 【Features of Hamai's anti-static valve】 ● Rare threaded ball valve with anti-static function ● Easy-to-operate lever handle ● Handle shape can be changed according to customer requests * We do not guarantee against fire-related issues such as leaks of flammable fluids. Please confirm the compliance of the fluid used with applicable regulations on your own. * For more details, please refer to the related links or feel free to contact us.
