A new pressure gauge coated with non-metallic all-fluoropolymer has been introduced. It is resistant to damage even when exposed to chemicals from the outside, and all wetted parts are made of fluoropolymer. This eliminates system troubles caused by pressure gauge failures, stabilizes production, and prevents production losses due to production stoppages. Additionally, by replacing pressure gauge products that have repeatedly failed due to external chemicals, the frequency of replacements is reduced. The internal sensor is covered with PTFE and does not come into contact with the fluid. The flow path is designed to be straight, allowing for minimal pressure loss when installing the pressure gauge and enabling easy flow and accurate measurement even with highly viscous fluids. (A connection type with fittings is also available.) As of 2025, the measurement range is 0 to 6 bar, but there are plans to support other ranges in the future. It can be combined with our block valve solutions to propose a more compact system solution.

[Question] What is the recommended torque for maintenance of a diaphragm valve? [Answer] The tightening torque varies depending on the size and material of the diaphragm. If the tightening is too strong, it can deform the diaphragm or cause it to wear out more easily, leading to leaks. Please download the diaphragm valve torque table for reference! *The values listed in the data are reference values for appropriate torque to preserve the diaphragm.*

**Contents of this Catalog** More than half a century ago, when we first debuted our products, creating compact valves became one of GEMU's major missions. From that aspiration, we developed valves that reduce material usage by 50% compared to conventional valves and created block valves that innovate piping structures. Today, we believe that these efforts have borne fruit, contributing to the compactness of equipment and ultimately to energy savings in factories. This is likely why about 80% of the global pharmaceutical industry uses GEMU valves. This catalog introduces how GEMU valves are utilized in various processes across different industries. If you are considering the use of sanitary valves in process industries, please take a look or feel free to contact us.
