The 070x16 Series direct-operated solenoid valve from VUOTOTECNICA is purpose-built for vacuum handling and automation systems. Its 3/2 normally closed (NC) configuration provides reliable control of vacuum circuits, with direct-operated actuation requiring no minimum pressure differential — the valve operates across the full 1–1500 mbar absolute pressure range.

Why Choose a Vacuum-Specific Solenoid Valve Over a General Pneumatic Valve?

General-purpose pneumatic solenoid valves are optimised for positive pressure applications and may not seal reliably under vacuum conditions. The 070x16 Series features an anodised aluminium body with NBR nitrile rubber or Vulkollan seal materials specifically selected for vacuum service, ensuring consistent shut-off performance from rough vacuum to low positive pressure. The 3 mm internal outlet tube is engineered for vacuum flow characteristics rather than general pneumatic duty.

What Electrical Protection and Connection Options Are Available?

The solenoid coil is fully resin-encapsulated for waterproof operation and achieves IP54 protection as standard, upgraded to IP65 when the EN 175301-803 (formerly DIN 43650) connector is inserted. The coil rotates 360° and the connector rotates 180° for flexible installation alignment. Insulation Class F (155°C) ensures reliable operation in demanding industrial environments.

• Standard models: 20 VA (AC) / 18 W (DC)
• Compact models (070016–070020): 8 VA (AC) / 6.5 W (DC)
• Voltage tolerance: ±10% of nominal

Frequently Asked Questions

What is the difference between NBR and Vulkollan seal materials?

NBR (nitrile rubber) provides excellent sealing for general vacuum applications, while Vulkollan — a high-performance polyurethane elastomer — offers superior abrasion resistance and longer service life in high-cycle applications where the valve opens and closes frequently.

Can the 070x16 Series be used for positive pressure applications?

The 070x16 Series is rated for operation from 1 mbar absolute up to 1500 mbar absolute (approximately 0.5 bar gauge). While primarily intended for vacuum service, it can handle low positive pressures within this range.
