Reply 1# chenshuanzhu cannot replace it! This is because a flame arrester is designed to prevent sudden backflow of flames, while a check valve remains open under normal operating conditions. Since the speed at which backflow occurs is higher than the speed at which the valve can respond, it cannot be used as a substitute. Never rely on luck – it’s a matter of principle, and care must be taken!
