This information can be found on the nameplate, the marking on the tank pocket (number series) and sometimes on the valve handle. SOTRALENTZ-branded valves have the text ON-OFF on the handle (see picture). Is my current valve compatible? Regardless of the color of the body (white or black) or the handle of your Sotralentz valve (red, white or gray), our valve replaces your existing valve if it is equipped with an aluminum ring with an inner diameter of 56 mm. Warning: Some valves are welded to the tank (see picture), in this case you do not have an aluminum ring: unfortunately you cannot change the valve. If you are unsure, do not hesitate to contact us by email explaining your request and attaching pictures: - Either of your current valve: front and 3/4 photos of your valve - Either of the threaded outlet of the tank (Thank you in advance for checking the quality of your photos, blurry photos cannot be processed).
