Gemü

Gemü is a leading German manufacturer of industrial valves and process control technology with over a hundred years of experience in fluid and gas management. With a catalog of 1,596 products, Gemü delivers solutions for the pharmaceutical industry, food sector, chemical industry, water treatment and biotechnology. The product portfolio includes diaphragm valves, butterfly valves, ball valves, control valves, solenoid valves and integrated process controllers.

Gemü diaphragm valves are the company's core products and are globally recognized for their superior sealing and contamination-free fluid control. The diaphragm completely separates the flow medium from the actuator, which is essential in aseptic processes such as pharmaceutical manufacturing, biotechnology fermentation and food processing. Gemü diaphragm valves are available in various plastic and stainless steel versions with EPDM, PTFE or silicone diaphragms for optimal media compatibility.

Gemü butterfly valves provide precise volumetric shut-off with minimal pressure drop, suitable for controlling large flow volumes in pipelines from DN50 to DN300. These valves are available with pneumatic or electric actuators and can be equipped with position feedback signals for advanced process automation. Gemü ball valves guarantee leak-tight closure in both low-pressure and high-pressure installations.

Gemü solenoid valves control pneumatic actuators in fully automated process installations. They are available as 2/2-way, 3/2-way and 5/2-way types for various circuit configurations, with direct or pilot-operated control depending on the required fluid flow. Gemü control valves with integrated positioner provide proportional actuation for precise flow regulation.

At Verkopershulp.nl you will find the complete Gemü range with technical documentation, dimensional drawings and material compatibility data. Our technical specialists support you in selecting the correct valve type, material specification and actuator configuration for your process installation.

History

Gemü was founded in 1922 by Georg Müller in Ingelfingen-Criesbach, Germany. The company started as a small mechanical workshop and quickly specialized in the production of valves for industrial process installations. In the 1960s, Gemü developed its first diaphragm valves, which marked a breakthrough for the pharmaceutical and food industries. The family-owned company continued to grow and expand into related valve and control technologies. In the 1990s, Gemü opened production facilities in Asia and North America. Today, Gemü has subsidiaries in more than 50 countries, holds ISO 9001 and FDA certification, and supplies products to more than ten thousand customers in over one hundred countries worldwide.

Frequently Asked Questions

What are the advantages of Gemü diaphragm valves for the pharmaceutical industry? ▾
Gemü diaphragm valves guarantee complete separation of the process medium from the actuator, making contamination by lubricants or packing materials impossible. The smooth flow path without dead zones meets FDA and GMP guidelines for aseptic production. Diaphragm valves are easily cleanable via CIP/SIP procedures without disassembly.
What diaphragm materials are available for Gemü valves? ▾
Gemü offers diaphragms in EPDM, NBR, PTFE, silicone and FKM (Viton). EPDM is suitable for water, steam and weak acids; PTFE for aggressive acids, bases and solvents; silicone for food contact and high temperatures up to 150°C. Material selection depends on the process medium and required temperature resistance.
Are Gemü valves suitable for sanitary (hygienic) applications? ▾
Yes, Gemü offers an extensive range of EHEDG- and FDA-certified hygienic valves for the food and pharmaceutical industries. These models feature polished stainless steel internal surfaces (Ra ≤ 0.8 μm), O-ring-free designs and self-draining configurations to prevent microbiological growth.
What is the maximum operating pressure of Gemü valves? ▾
Standard Gemü diaphragm valves are rated to 10 bar gauge pressure. Ball valves are available up to 100 bar for high-pressure applications. Butterfly valves for pipelines typically operate up to 16 bar nominal pressure. Check product specifications for exact pressure and temperature limits per model.
Can I equip Gemü valves with an electric actuator for full automation? ▾
Yes, most Gemü valves are available with integrated electric or pneumatic actuators. Electric actuators offer precisely controllable positioning and are suitable for proportional control or fail-safe position functions. Pneumatic actuators are more cost-effective for on/off switching at high switching frequencies.
How are Gemü valves calibrated for precise flow regulation? ▾
Gemü control valves are equipped with integrated positioners that continuously monitor the valve position and compare it with the control signal (4-20 mA or 0-10 V). Automatic calibration via SMART electronics compensates for wear and hysteresis. This guarantees a control precision of better than ±1% of full scale.
What certifications do Gemü valves carry? ▾
Gemü valves hold various certifications depending on the model: ISO 9001, CE marking per PED (Pressure Equipment Directive), FDA conformity for food contact, ATEX for explosion-proof versions, and EHEDG for hygienic applications. Specific certification documentation is available via Verkopershulp.nl.
Does Verkopershulp.nl offer technical support for selecting Gemü valves? ▾
Yes, Verkopershulp.nl has technical specialists who support you with valve selection, material specification, actuator configuration and installation advice for Gemü products. We can also assist in compiling valve schedules and technical specifications for project orders.
