SMC VX2 Series Direct-Operated 2-Port Solenoid Valve (CAS006-1)
Description
Overview: A Configurable Direct-Acting Valve Platform
The SMC VX2 solenoid valve series is a direct-operated, 2-port valve family covering the VX21, VX22, and VX23 body sizes, engineered for a wide variety of media including air, gas, vacuum, water, steam, and oil. Because valve body material, seal material, and coil class are independently selectable, the VX2 platform can be configured for many different service conditions from a single core mechanical design, making it a versatile standard solenoid valve choice across process, utility, and pneumatic control applications.
As a trusted supplier of SMC pneumatic and process valve components, Seven Star LLC sources and supplies the VX2 Series solenoid valve to refineries, gas processing plants, and manufacturing facilities across Oman and the wider GCC. Because correct body and seal material selection is critical to service life in each specific application, Seven Star LLC helps engineering teams configure the correct VX2 variant for their fluid and pressure conditions.
Working Principle: Direct-Acting Poppet Shut-Off
The VX2 is a direct-operated 2-port valve, meaning the solenoid coil directly lifts or seats the valve’s poppet element against its seat without relying on a pilot pressure differential to assist actuation. This direct-acting principle allows the VX2 to operate reliably from zero differential pressure up to its rated maximum, unlike pilot-operated designs that may require a minimum pressure differential to function correctly – an important consideration for applications where line pressure at the valve may be low or variable.
Body and sealing material selection determines fluid compatibility: brass or stainless steel bodies with NBR, EPR, FPM (FKM), or PTFE seals cover water, steam, and oil service, while aluminum or resin bodies serve general air and vacuum applications. Class B or Class H solenoid coil options allow the valve to be matched to ambient and media temperature requirements, with Class H suited to higher-temperature service such as steam applications up to approximately 183°C in dedicated steam variants.
Engineering Design of the VX2 Series
The VX2 is available in three body sizes with port sizes ranging from 1/8 to 1/2 inch, and flow rates (Cv) from approximately 0.23 to 2.21 depending on body size and configuration. The valve carries an IP65 enclosure rating for protection against dust and water jets, and conforms to UL94V-0 flame resistance standards for the coil housing material, an important consideration for installations subject to fire safety code requirements.
Power consumption scales with body size: approximately 4.5 W for size 1, 7 W for size 2, and 10.5 W for size 3, and a special coil construction improves service life compared to earlier shading-coil designs. This combination of configurable materials, direct-acting reliability, and compact IP65 construction makes the VX2 suitable for both dedicated process fluid control and general pneumatic system shut-off duties.
Key Features
The SMC VX2 Series Direct-Operated 2-Port Solenoid Valve delivers configurable, reliable fluid shut-off. Key characteristics include:
- Direct-operated poppet design functioning from zero differential pressure to rated maximum.
- Configurable body material (brass, stainless steel, aluminum, resin) for fluid compatibility.
- Configurable seal material (NBR, EPR, FPM, PTFE) to match media and temperature.
- Port sizes from 1/8 to 1/2 inch; Cv range approximately 0.23 to 2.21.
- IP65 enclosure rating; UL94V-0 flame-resistant coil housing.
- Class B or Class H coil insulation options for temperature-demanding applications.
- Suitable for air, gas, vacuum, water, steam, and oil service depending on configuration.
Industrial Applications
The VX2 Series is deployed across refinery utility systems, gas processing plants, and general manufacturing automation wherever a compact, direct-acting 2-port valve is needed to shut off or admit flow of air, water, steam, or process fluids. Its configurable material options make it equally suited to compressed air system isolation and to more demanding process fluid control duties within the same valve family.
Seven Star LLC supports refinery instrumentation teams, gas processing operators, and manufacturing plant maintenance departments across Oman, Muscat, Sohar, and the broader GCC region with sourcing of SMC VX2 solenoid valves, helping projects match the correct valve configuration to their specific fluid service.

Why Choose Seven Star LLC for SMC VX2 Series Solenoid Valves
The VX2 platform spans multiple orifice sizes, voltage options, seal materials, and port configurations, so the part number that looks correct on a datasheet can still be the wrong build for your actual media, pressure range, or panel wiring. Seven Star LLC confirms the exact VX2 configuration against your application — compressed air, vacuum, or compatible fluid service — before the order ships, avoiding a costly reorder cycle. We also support GCC customers who standardize on SMC pneumatic components across multiple skids or panels by coordinating batch orders and consistent lead times, and by keeping common VX2 variants available for fast replacement when a valve reaches end of service life in continuous-duty automation systems across Oman.

About brand
SMC is the Japanese specialist in pneumatic automation: air preparation units, solenoid valves, cylinders, fittings, process valves and sensors. Yoshiyuki Takada founded the company in Tokyo on 27 April 1959 as Shoketsu Kinzoku Kogyo, which means Sintered Metal Corporation, and its first products were sintered metal filters. SMC Corporation is headquartered in Tokyo and listed on the Tokyo Stock Exchange, and its products are used on machines and instrument air lines across the world.
Seven Star LLC, an independent supplier in Oman, lists SMC AW series filter regulators (AW20 and AW40) and the VX2 series direct-operated 2-port solenoid valve, and sources other SMC parts by full part number.

SMC series listed on this page
The AW is a combined filter and pressure regulator in SMC's modular air preparation line. The body size is in the name: AW20 is the smaller unit and AW40 the larger, and the digits after the dash give the port size. A part number such as AW40-04-A therefore describes body size, port and options in one string. The VX2 is a direct-operated two-port solenoid valve for shutting off air, water, oil or steam, depending on the body and seal materials chosen.

Ordering SMC parts: what we need
Give the complete SMC part number from the label, including thread prefix, options and the final suffix letter. For AW units state gauge, drain type and bracket if you need them. For VX2 valves send coil voltage, port size, orifice, body and seal material, and the fluid. Buyers in the GCC often have NPT or G threads on site, so say which thread standard the piping uses.
