ROS solenoid valves are electromagnetically controlled industrial devices, fundamental components for fluid control in automation. They are actuators, not limited to hydraulic or pneumatic systems. Used in industrial control systems to adjust the direction, flow rate, speed, and other parameters of the medium. Solenoid valves can be used with different circuits to achieve the desired control, ensuring both precision and flexibility. There are many types of solenoid valves, each playing a different role in the control system. Common types include check valves, safety valves, directional control valves, and speed control valves.

ROS Solenoid Valve Selection Criteria:

1. Select the solenoid valve based on pipeline parameters: nominal diameter (DN) and connection type

1) Determine the nominal diameter (DN) based on the inner diameter of the pipeline or flow requirements;

2) For connection type, generally, >DN50 requires a flange connection, while ≤DN50 can be freely selected according to user needs.

2. Selecting Solenoid Valves Based on Fluid Parameters: Material and Temperature Group

1) Corrosive fluids: Corrosion-resistant solenoid valves and all-stainless steel valves are recommended; Ultra-clean edible fluids: Food-grade stainless steel solenoid valves are recommended.

2) High-temperature fluids: Solenoid valves made with high-temperature resistant electrical and sealing materials should be selected, and piston-type valves are preferred.

3) Fluid state: Fluids can be gaseous, liquid, or mixed, especially when the diameter is greater than DN25, these must be clearly distinguished.

4) Fluid viscosity: Generally, any viscosity can be selected below 50 cSt. If it exceeds this value, a high-viscosity solenoid valve should be selected.

3. Selecting Solenoid Valves Based on Pressure Parameters: Principle and Structural Types

1) Nominal pressure: This parameter has the same meaning as other general-purpose valves and is determined by the nominal pressure of the pipeline.

2) Working pressure: If the working pressure is low, a direct-acting or step-direct-acting principle valve must be selected; when the minimum working pressure difference is above 0.04 MPa, direct-acting, step-direct-acting, and pilot-operated valves can all be selected. 4. Electrical Selection: AC220V or DC24V voltage specifications are preferable for convenience.

5. Selection Based on Continuous Operating Time: Normally Closed, Normally Open, or Continuously Energized

1) When the solenoid valve needs to be open for a long time, and the duration is longer than the closing time, a normally open type should be selected.

2) If the opening time is short or the opening and closing times are infrequent, a normally closed type should be selected.

3) However, for some safety protection applications, such as furnace and kiln flame monitoring, a continuously energized type cannot be selected; a type that can be continuously energized should be chosen.

6. Selection of Auxiliary Functions Based on Environmental Requirements: Explosion-proof, Check Valve, Manual Operation, Water-resistant Fog, Water Spray, Submersible.

ROS engages you in the process, developing better solutions for your pneumatic applications. ROSS/FLEX® has a specially trained design engineering team with specialized equipment and a truly advanced fully automated manufacturing system to help you achieve your needs. Ultimately, we will provide you with a comprehensive system solution, developed and manufactured according to your requirements and timeline. This is a unique approach that utilizes capabilities currently only available from ROSS.

The basic concept is simple: using products tailored to your application is better than using generic products.

Cost. In the past, this often involved numerous engineers, designers, production planners, technicians, and others. It also frequently required new equipment, special processing, new materials, or other manufacturing costs. ROSS/FLEX™ technology eliminates these costs and significantly reduces the time required to develop solutions. Design, prototyping, testing, modification, and re-prototyping and testing all take a significant amount of time and can be repeated indefinitely.

ROS/FLEX™ services deliver conceptual drawings and working prototypes in a timely manner, and also allow for timely modifications.

You don't need to worry about having only one supplier to integrate all your other equipment, because ROSS/FLEX™ services can design and manufacture products compatible with any brand. Furthermore, all working parts are proven ROSS parts, available globally from ROSS and its distributors.

ROSS/FLEX? is not a product line.

The ROSS/FLEX? process is a manufacturing culture designed to help you reduce costs while increasing the actual value of your air control and pneumatic systems. It puts energy back where it should go—in the hands of your customers!

We believe customers deserve products that meet their requirements in both functionality and price.

If you're building a machine that requires six different air control units, and you can improve that design by using a machine that controls all six functions, then you should have this machine.

That's why we bring you ROSS/FLEX? services.

ROS lift valves open and close almost instantly. The surface areas of the piston lift valve, exhaust lift valve, and inlet lift valve are carefully calculated to generate strong movement and sealing forces in every direction. This design ensures high speed, repeatability, and high movement force.
