The plastic diaphragm valve is a special type of cut-off valve. Plastic diaphragm valve and other valves are different in that: the use of no stuffing box structure; The rubber diaphragm isolates the corrosive medium in the passage from all the driving parts, eliminating the usual "run, run, drip, leak" of the valve.
Note: parameters are for reference only, or incomplete. Valves can be selected according to the requirements of different pressure, material, diameter, driving mode. Please contact us by phone or online.
