Description
3/8" Stainless Steel High Vacuum Solenoid Valve – ADS-14-V-G2-V
316 Stainless Steel Zero-Rated Vacuum Solenoid Valve – Full Vacuum to 10 Bar
The CS Fluid Power ADS-14-V-G2-V is a high-performance 3/8" 316 stainless steel vacuum solenoid valve designed for reliable control and isolation of industrial vacuum and compatible gas systems.
Using a 2/2 way normally closed, zero-rated assisted-lift design, the valve operates from high vacuum at -101 kPa (99.67% vacuum) through zero differential pressure and into positive pressure.
Featuring a 15 mm orifice with Cv 4.5, combined with a corrosion-resistant 316 stainless steel body and stainless steel internals, the ADS-14-V is particularly suited to demanding industrial, laboratory, semiconductor and automated vacuum applications.
Valve Function & Operation
Function: 2/2 way normally closed
Operation: Assisted lift, zero rated
The ADS-14-V remains closed when electrical power is removed. Energising the solenoid operator opens the valve, allowing flow through the 15 mm internal orifice.
The zero-rated assisted-lift design enables the valve to operate without the minimum pressure differential normally required by conventional pilot-operated solenoid valves.
This provides reliable operation from high vacuum through zero differential pressure and into positive-pressure applications.
Ports & Connections
Port size: 3/8" BSPP
Optional:
✓ NPT thread
✓ Rc thread
Orifice: 15 mm
The combination of a compact 3/8" connection and relatively large 15 mm internal orifice provides excellent flow capacity for vacuum control applications.
Vacuum & Pressure Performance
Vacuum rating: -101 kPa
Equivalent vacuum:
757.56 mmHg relative
99.67% vacuum
Maximum AC pressure: 10 Bar
Maximum DC pressure: 7 Bar
Cv flow factor: 4.5
The ADS-14-V provides reliable operation across vacuum, zero differential and positive-pressure conditions.
Construction & Materials
Body: 316 stainless steel
Tube and internal parts: Stainless steel
Seals and gaskets: FKM / Viton
Moulded coil: Resin
Maximum media temperature: +120°C
Ambient temperature: -20°C to +60°C
Mounting position: Coil upright
Opening / closing time: 50 ms maximum
The 316 stainless steel construction provides improved corrosion resistance compared with the equivalent brass-bodied vacuum valve and makes the ADS Series particularly useful for more demanding industrial environments.
Seal & Media Compatibility
Standard seals: FKM / Viton
Suitable for:
✓ Vacuum
✓ Air
✓ Compatible gases
✓ Compatible process fluids
FKM provides good resistance to many industrial gases, oils and process fluids, while the 316 stainless steel body provides excellent general corrosion resistance.
For specialist gases, aggressive chemicals, oxygen or high-purity applications, compatibility and application requirements should be confirmed before ordering.
Coil & Electrical
Standard coil: WPG2
Duty cycle: 100% continuous
DC power: 18 Watts
AC power:
18.7 VA inrush
15.3 VA holding
Insulation: Class H, 180°C
Protection: IP67 with connector
Electrical connection: DIN43650A
The WPG2 industrial solenoid operator provides reliable continuous-duty operation and is supplied with an IP67 LED DIN connector.

ATEX Certificate: PTB 03 ATEX 2086 X
IECEx Certificate: IECEx PTB 05.0005X
ATEX Directive: 2014/34/EU
When fitted with the ATEX / IECEx operator, the operating range is vacuum through to +3 Bar.
The ATEX / IECEx certification relates to the explosion-protected solenoid operator rather than certification of the complete stainless steel valve assembly.
Optional Manual Override
A top-mounted lift-and-turn manual override is available for manual valve operation during commissioning, testing and maintenance.
Typical Applications
✓ Industrial vacuum systems
✓ Pick-and-place automation
✓ Vacuum handling equipment
✓ Semiconductor manufacturing
✓ Packaging machinery
✓ Laboratory vacuum equipment
✓ Vacuum chambers
✓ Process automation
✓ OEM machinery
✓ Automated production equipment
316 Stainless Steel Vacuum Control
The ADS-14-V-G2-V combines 316 stainless steel construction, a 15 mm orifice and Cv 4.5 with zero-rated assisted-lift operation.
Its ability to operate from -101 kPa high vacuum through zero differential pressure and into positive pressure makes it a versatile solution where both vacuum performance and corrosion-resistant construction are required.
The stainless steel construction also makes the ADS Series a useful alternative to the equivalent brass AD Series for more demanding environments and compatible process media.
