Block valve (without dead leg)

Complexly combined piping requires a large space, which naturally leads to dead legs and reduces the quality of the fluid. Additionally, there is a risk of leaks from welded joints, and the more complicated the piping becomes, the lower the system's performance. However, GEMU offers the "Multi-Port Block Valve," which consolidates such complex piping into a single block. The block, made from a single piece through complete machining, eliminates the risk of leaks, achieves space-saving, and contributes to the overall improvement of the system's performance. Since it can be custom-made for various applications, please feel free to contact us.

A new standard in piping design: "Do not create dead legs in branch pipes."

A new solution called "multi-functional block valve" that enables space-saving, eliminates dead legs, and improves product safety through complete customization.

GEMÜ (GEMU) manufactures "multi-functional block valves" that are designed and produced one by one to meet the customer's specifications in a fully customized manner. 【Features】 1. Eliminates concerns about liquid accumulation by minimizing dead legs. 2. Reduces valve piping space by over 50%. 3. Significantly reduces piping labor and material costs. 4. Greatly reduces validation workload. If you are using diaphragm valves, please check the detailed information below.

High Purity Multiport Block Valve

New proposal for miniaturization and lightweighting of equipment for the semiconductor industry.

GEMÜ's multi-port block valves are designed and manufactured one by one to meet the customer's specifications, fully customized. With a space-saving design using a manifold, the number of connection points is minimal, which also reduces the risk of leaks. ★ Advantages of Multi-Port Block Valves 1. There is no dead leg, so there is no concern about liquid accumulation. 2. The piping space for the valves is reduced by more than 50%. 3. It can reduce the labor and material costs associated with piping.

Sampling Bottle: Perform sterile sampling safely and efficiently!

New standards for liquid sampling in pharmaceuticals, food, cosmetics, biotechnology, and chemicals.

The "GEMÜ Sampling Bottle" was born from the application of GEMÜ's block valve technology. Since the valve can be removed from the piping and transported along with the sampling bottle, the possibility of contaminating the liquid is extremely low, and the safety of the operator can also be maintained! Additionally, GEMÜ's block valve technology enables the reduction of piping space and achieves a dead leg of zero. It can be individually adapted to existing equipment, making it usable for any application (please check the detailed information section for individual adaptation examples).
