Technical Specifications:
The solenoid valves are designed for cryogenic service with internal parts made of stainless steel and PTFE seals. They operate effectively with fluid temperatures ranging from -196°C to +90°C and ambient temperatures up to +50°C. The valves support a maximum viscosity of 21 mm²/s and have a response time between 8 to 40 ms for closing. They are compatible with various voltages including 230, 115, 48, 24 V AC, and 24, 12 V DC, and are designed for continuous duty cycles (ED100%). The cycling rate ranges from 10 to 100 cycles per minute, and they offer IP65 electrical protection when used with a plug conforming to ISO 4400 standards. Long-term use in humid environments requires sealing sets.

Valve Features:
These high-performance valves are either direct acting or pilot-operated, with brass bodies and PTFE seals, suitable for continuous service with cryogenic fluids like liquid nitrogen (LN2) and liquid carbon dioxide (LCO2). They are normally closed (NC) when de-energized, featuring a conical seal for excellent shutoff and durability.

Valve Models and Specifications:
The document lists various models with different port sizes, orifice sizes, Kv values (flow rate in l/min at 1 bar), differential pressure ranges, body materials, seal types, mass, coil types, and order codes. For example, a G1/4 valve with a 3 mm orifice has a Kv of 3.6 l/min and operates between 0 to 30 bar differential pressure.

Options and Customization:
The valves can be customized with options such as EEx me II explosion-proof coils, NPT ports, and other versions upon request.
