The bellows valves designed by CHASE VALVE are generally used in conditions that leakage grades are strictly required, causing damage to operators or damage to the environment. The upper and lower ports of the bellows are fixed on the bonnet and the stem respectively. When the stem moves up and down, it drives the bellows to stretch to eliminate the potential leakage caused by the sliding of the stem.
