The new SVH-120 Series is a versatile, ¼ or ½" full port, high pressure, pilot operated, solenoid valve. The SVH-130 Series is a compact size, for where space is limited. The compact SVH-120 Series is ideal for flow control of high pressure air, water, compressed natural gas (CNG), hydrogen, nitrogen, and other gases or light liquids compatible with the materials of construction, and leverages this high pressure flow to its own advantage in operating effectively and efficiently.

The SVH-120 style valve is perfect for use in hydrogen dispensing tanks, commonly used in the refueling of fleet vehicles. It is also a used in many compressed natural gas applications. With available pressures to 10,000 psig there are a wide range of applications that include water, nitrogen and many other compatible liquids. This solenoid valve must be mounted with the solenoid upright and vertical.

Are these valves compatible with oxygen gas?

Asked by: Propulsion Engineer RV
Hello, for Oxygen cleaned units add “-OX” to the model number, for an additional charge. For price and lead time kindly email us at

I couldn't find the DC voltage rating for it. Could you please provide that?

Asked by: Salman
Thank you for your inquiry! All of the standard coils will be 10 watt coils. The maximum pressure vs. coil type can be seen on page two of the data sheet on the product page. If you have any further questions please feel free to contact us at

Can this be mounted in the open on the exterior of a building, or does it need to be mounted inside an enclosure? What is the exterior exposure rating?

Asked by: hockeytown
The SVH-120 Series solenoid valves do not have any IP or NEMA environmental ratings. They should not be used outdoors.

Are these valves compatible with seawater? Can they be disassembled for service if corrosion is an issue?

Asked by: Anonymous
The SVH solenoid valves are not compatible with seawater.

Can the valves seal against the full rated pressure in the reverse direction when closed; or will the valve be forced open? If it will open, what would the approximate cracking pressure be (can be stated as a % of the rated pressure).

Asked by: JoeP1
Thank you for your inquiry! These valves are not designed to have greater pressure on the outlet side and will not prevent flow in the reverse direction. Unfortunately, we do not have a specified value for cracking pressure as this condition should not occur in normal operation.

Is there a manual for how to properly disassemble this valve?

Asked by: Ramuel
Thank you for your inquiry. Please email the Flow Group at and will send the information you requested.
