How much do I need to turn the handle for it to close? Solved!!

Aren't you worried about how much to tighten the handle before it closes, and end up tightening it too much? Over-tightening the handle can lead to damage to the diaphragm that stops the fluid. This product comes standard with a system called "Seal Adjuster," which allows you to adjust the fully closed position of the valve! By using this system, you can achieve: 1. Prevention of diaphragm failure due to over-rotation of the handle 2. Adjustment of flow rate. There is a clear difference in strength between women and muscular men, which affects how much force they can apply to turn the handle. However, by setting the fully closed position, anyone can close the valve at the same position regardless of their strength! Additionally, it can fulfill the desire to adjust the flow rate consistently just by turning the handle. Setting the Seal Adjuster is also very easy!

[Diaphragm Valve Technical Information] Advantages and Precautions of PTFE Sealed Valves

[Diaphragm Valve Technical Information] Advantages and Precautions of PTFE Sealed Valves

The driving parts are not corroded by fluids! Introducing technical information on Teflon seal valves.

The advantages of the "PTFE (Teflon) seal valve" are that the drive part and the valve body part through which the fluid flows are separated, preventing the drive part from being corroded by the fluid. Since PTFE is used in the diaphragm and valve seal section, it has high corrosion resistance, is heat-resistant, and is less prone to dirt, making it easy to clean. Additionally, a point to note is that it is very sensitive to dust and debris, so it is necessary to install filters or similar devices to prevent foreign substances from mixing with the fluid. We offer an option called "soft seal," which uses a special elastomer known as perfluoroelastomer, which has excellent chemical resistance, to minimize the occurrence of scratches in the seal section. 【Advantages of PTFE Seal Valve】 ■ High corrosion resistance ■ Heat-resistant and less prone to dirt ■ Easy to clean *For more details, please refer to the PDF materials or feel free to contact us.
