With the new, high-performance GEMÜ D40 diaphragm valve, valve manufacturer GEMÜ is launching a new valve type that is geared towards the requirements of the market. The GEMÜ D40 has been equipped with an innovative diaphragm technology and optimized with respect to its design, which enables an increase in performance at plants. This new valve product represents a further step towards the future for GEMÜ.

The pneumatically operated GEMÜ D40 diaphragm valve is designed for use in sterile applications. The diaphragm hermetically separates the actuator from the working medium. In addition, the GEMÜ D40 particularly impresses with its simple, safe and fast maintenance. The actuator is mounted via a defined union end on block (metal on metal) with only four collar nuts.

Likewise, the diaphragm with bayonet pin facilitates installation, while the new diaphragm technology offers greater safety and precision in plants. Due to the new seal system with fixed chambering, the natural setting behaviour of the diaphragm is controlled such that it is no longer necessary to retighten the diaphragm. The optimized rolling behaviour of the diaphragm provides better controllability and ensures low stress on the diaphragm, meaning that maintenance intervals can be adapted to specific applications if necessary.

Diaphragm valve with many advantages

The optimized body design not only saves weight but also ensures a high flow and homogeneous flow characteristics. This enables the GEMÜ D40 to achieve up to 100% higher Kv values. This increase in performance allows smaller valves to be used and therefore enables more compact planning of plants and a high degree of flexibility.

The GEMÜ D40 diaphragm valve combines high performance with a state-of-the-art process solution that stands out with its simple operation, compact design and high process efficiency. As a key part of the new, innovative product generation from GEMÜ, it sets new standards in valve designs.

New product generation 

With the launch of the newly developed, innovative product generation, GEMÜ is taking a step into the future. ‘LEAP into the future’, with its abbreviation for “Lean. Effective. Agile. Platformized.”, embodies both progressive products in a modular design and innovative production methods.

The pioneering products of the GEMÜ LEAP product generation not only include the GEMÜ D40, but also two further valves and an add-on component:

• GEMÜ S40 – the pneumatic globe valve with angle seat and straight seat designs
• GEMÜ P40 – the efficient tank bottom valve with PD design
• GEMÜ 12A0 – the intelligent electrical position indicator

The new valves have actuator modules on a uniform platform architecture to enable flexible adaptation to different requirements. The GEMÜ 12A0 electrical position indicator is characterized by modern communication interfaces and an integrated sensor system. It is compatible with the valve types from the new product generation and offers a space-saving and simple automation option.
