Solenoid Valve Assembly for Ingredient Inlet Manifold

Product Specifications

Technical details and manufacturing context for Solenoid Valve Assembly

Definition

A solenoid valve assembly is a critical component within an Ingredient Inlet Valve Manifold, responsible for the precise on/off or proportional control of fluid (liquid or gas) ingredient flow into a process. It converts electrical signals into mechanical movement to open or close the valve port. The assembly typically consists of a solenoid coil, a plunger or armature, a spring, and a valve body with inlet and outlet ports. When an electrical current is applied to the coil, it generates a magnetic field that moves the plunger, either opening or closing the orifice. De-energizing the coil allows the spring to return the valve to its default state. This product is designed for use in industrial machinery and equipment manufacturing, particularly in applications requiring accurate dosing or flow control of ingredients. The valve is available in nominal diameters from DN15 to DN50, with an operating pressure range of 1.0 to 1.6 MPa. The flow coefficient (Cv) ranges from 2.5 to 8.0, and the leakage rate is ≤0.01% of rated flow, exceeding Class VI seat leakage requirements. Response time is between 10 and 30 ms, and coil voltage is 24 V DC ±10%. Power consumption is 5 to 12 W, and operating temperature ranges from -40 to 85 °C. The ingress protection rating is IP54 to IP65, suitable for washdown environments. The body is made of CF8M stainless steel (ASTM A351), and seals are PTFE (ASTM D4894) or EPDM. Weight ranges from 1.5 to 4.0 kg. All values are reference ranges and must be verified for the specific model and application with the legal manufacturer or supplier.

Working Principle

When an electrical current is applied to the solenoid coil, it generates a magnetic field that moves a plunger or armature. This mechanical movement either opens or closes the valve orifice, allowing or stopping the flow of the ingredient. De-energizing the coil typically returns the valve to its default state via a spring. The valve can be normally closed or normally open depending on the spring configuration. The response time is critical for precise dosing, and the flow coefficient determines the pressure drop at a given flow rate.

Frequently Asked Questions

What is the operating pressure range for this solenoid valve assembly?

The operating pressure range is 1.0 to 1.6 MPa. Always verify the exact pressure rating for your specific model with the manufacturer.

What is the response time and why is it important?

The response time is 10 to 30 ms, as per IEC 60534-4. This is critical for precise ingredient dosing, as faster response allows for more accurate control of the flow. Confirm the response time for your application with the supplier.

What materials are used for the body and seals?

The body is made of CF8M stainless steel (ASTM A351), which is corrosion-resistant. Seals are made of PTFE (ASTM D4894) or EPDM, depending on chemical compatibility with the ingredients. Verify material compatibility with your process fluids.

What is the ingress protection rating and what does it mean?

The ingress protection rating is IP54 to IP65, as per IEC 60529. IP65 is suitable for washdown environments, providing protection against dust and water jets. Choose the appropriate rating based on your installation environment.
