3/2-Way NC Valve

Staiger GmbH & Co. KG

3/2-way NC design with cartridge pneumatic connection.
Extremely fast switching times.
Compact 7 mm outer diameter with light weight (4 g).
Long service life and robust stainless-steel build.
Mounting position any.
IP50 (default) / IP65 (with plug).

The 3/2-Way NC Valve is a compact, fast-switching non-return valve with an outer diameter of 7 mm, designed for efficient operation and a long service life. It is suitable for air and inert gases, with the option to use it with other media after prior testing. The valve features a small design, high flow rate, and robust construction with stainless steel components, ensuring durability and versatility in various environments. It has a very small design, extremely fast switching times, and is suitable for a wide range of temperatures. The valve is equipped with flying leads for electrical connection, operates at a nominal voltage of 12 V DC, and has a nominal power consumption of 1 W. It is also IP50 protected in its standard delivery and can be upgraded to IP65 with a suitable plug. The valve is designed for easy installation and has specific tolerances and dimensions to ensure compatibility with various systems.

Use Cases

Pneumatic control of air or inert gases in compact systems.
Applicable in hydrogen support equipment after material compatibility testing.

Capabilities

Operates from 12 V DC, 1 W coil with flying leads (80 mm).
Handles 0–10 bar(g) working pressure, >20 bar(g) pressure resistance.
Delivers > 7 l/min flow rate through 0.3 mm orifice.
Temperature range (environment and medium) 5–50 °C; storage –10–60 °C.
Tightness < 1 ml/min internal/external; IP50/IP65 protection.

Staiger GmbH & Co. KG Staiger GmbH & Co. KG is a manufacturing company specializing in precision solenoid valves used in hydrogen and fuel-cell systems. The company’s broader business is based on fluid-control components and application engineering, with equipment selected according to media compatibility, pressure and temperature range, leakage requirements, connection standard, actuation, and the architecture of the surrounding system. The business is mainly B2B and specification-driven, with components selected or engineered to match the operating conditions and standards of the surrounding hydrogen equipment or plant. For hydrogen, the company applies this flow-control expertise to the specific valves, regulators, fittings, manifolds, or related assemblies identified in its hydrogen offering, rather than to hydrogen production as a standalone activity. Its compact valves control hydrogen, air, water, and other media in fuel-cell balance-of-plant and test applications. The company focuses on fast switching, low leakage, media compatibility, and customer-specific valve design for electrochemical systems. Within the hydrogen value chain, Staiger GmbH & Co. KG therefore serves mainly as a component supplier to equipment OEMs, plant builders, gas-system integrators, test facilities, and infrastructure operators.
