Crouzet is a French manufacturer with over 80 years of experience in control components and pneumatics. Their pneumatic product range is particularly well known for miniature and micro valves — components that bring pneumatic control to applications where space, weight and response time are critical parameters. This guide introduces the Crouzet pneumatic range and the applications it suits best.
Crouzet’s Pneumatic Specialisation
Where many valve manufacturers focus on standard industrial sizes, Crouzet has built a reputation in miniature pneumatics. Their solenoid valves start at body widths of just 10mm — significantly smaller than the standard ISO 5599 footprint — making them the preferred choice in applications where machine size, weight or packaging constraints rule out conventional valves.
This focus on miniaturisation is backed by a commitment to reliability in demanding environments. Crouzet valves are used extensively in medical devices, analytical instruments, semiconductor manufacturing equipment and food processing — sectors where component failure is costly and access for maintenance is limited.
Crouzet Solenoid Valve Series
The Crouzet pneumatic range includes several distinct valve series:
Miniature solenoid valves — the core product line, available in 2/2 and 3/2 configurations with port sizes from M5 to G1/8. Direct-acting designs operate at zero differential pressure, making them suitable for vacuum and low-pressure as well as standard compressed air circuits.
Pilot-operated valves — for higher flow requirements in compact form factors, available up to 5/2 configurations for double-acting cylinder control.
Bistable (impulse) valves — require only a brief electrical pulse to change state and then hold position without continuous power, reducing energy consumption in applications where valves are only switched occasionally.
Key Features of Crouzet Pneumatic Valves
- Long service life — many Crouzet valve models are rated for 50 to 200 million operations, suited to high-cycle automation
- Compact dimensions — miniature valves occupy a fraction of the space of standard industrial valves
- Low power consumption — Crouzet coil designs minimise power draw, reducing heat generation in compact enclosures
- Wide voltage range — available in 12V DC, 24V DC, 110V AC and 240V AC variants
- High IP ratings — IP67 variants available for washdown and outdoor applications
Typical Applications
Crouzet pneumatic valves are specified in applications including:
- Medical and laboratory equipment — ventilators, analytical instruments, dispensing systems where size and long life are critical
- Food and beverage — stainless steel and food-grade seal material options for washdown environments
- Packaging machinery — high-cycle valve operation on form-fill-seal and cartoning lines
- Semiconductor manufacturing — clean room compatible materials and ultra-low particle generation
- Automotive assembly — compact valves for fixture and tooling control
Selecting a Crouzet Pneumatic Valve
When specifying a Crouzet valve, key parameters are:
- Function required — 2/2 (on/off), 3/2 (single-acting cylinder), 5/2 (double-acting)
- Port size and flow requirement — M5 for pilot circuits, G1/8 for most miniature applications
- Operating voltage — 24V DC is standard for PLC-controlled systems
- Seal material — NBR for general air, FKM for aggressive environments
- Cycle life requirement — match to your expected production rate

Frequently Asked Questions
What is Crouzet known for in pneumatics?
Crouzet is best known for miniature and micro solenoid valves u2014 compact, long-life pneumatic valves with body widths starting at 10mm. They are widely specified in medical devices, analytical instruments, food processing and semiconductor equipment where conventional industrial valve sizes are too large.
What is a bistable pneumatic valve?
A bistable (or impulse) valve changes state with a brief electrical pulse and then holds that position without requiring continuous power. Unlike a standard solenoid valve that returns to its default position when de-energised, a bistable valve remains in its last set position until it receives a pulse to change. This saves energy in applications where valves switch infrequently.
Are Crouzet valves suitable for food and beverage applications?
Yes. Crouzet offers food-grade variants of their solenoid valves with stainless steel bodies, FKM seals and materials compliant with food contact regulations. Their IP67-rated versions are suitable for washdown environments common in food processing and beverage production.
