Control Solenoid Valve for Reject Mechanisms | Specifications & Verification

Product Specifications

Technical details and manufacturing context for Control Solenoid Valve

Definition

A control solenoid valve is an electromechanical component used in reject mechanisms to precisely regulate the flow of air or liquid for actuating rejection actions. It converts electrical signals into mechanical movement to open or close fluid pathways, enabling rapid and controlled rejection of defective items on production lines. The valve is available in nominal diameters from DN15 to DN50 (ISO 6708) and operates at pressures from 1.0 to 1.6 MPa. Its flow coefficient (Cv) ranges from 0.5 to 10 (IEC 60534-2-3), and response time is between 10 and 50 ms (ISO 12238). Leakage rate is ≤0.01% of rated flow (Class VI). The coil operates at 24 V DC ±10% (IEC 60038) with power consumption of 5–15 W (IEC 60534-2-3). Ambient temperature range is -20 to 60 °C, and media temperature range is -10 to 80 °C (IEC 60534-4). Ingress protection is IP54 to IP65 (IEC 60529). Body material is stainless steel CF8M (ASTM A351), and seal material is PTFE (ASTM D4894). Weight varies from 1.5 to 8.0 kg. Materials on file include brass, stainless steel, and plastic (POM/Nylon). These values are reference ranges; verify model-specific specifications with the legal manufacturer or supplier before procurement.

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 blocking fluid flow. When current is removed, a spring typically returns the valve to its default position. The valve's response time, typically 10–50 ms, determines how quickly the rejection action occurs. The flow coefficient (Cv) indicates the flow capacity at a given pressure drop, affecting the force available for rejection. The operating pressure range is 1.0–1.6 MPa. The valve's design, including materials and seals, must be compatible with the media and ambient conditions to ensure reliable operation.

Frequently Asked Questions

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

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 of the valve?

The response time, from signal to full stroke, is typically 10 to 50 ms (ISO 12238). Faster response times are generally observed for smaller valve sizes. Confirm the actual response time for your application with the supplier.

What materials are available for the valve body and seals?

Body materials on file include brass, stainless steel, and plastic (POM/Nylon). The standard body material is stainless steel CF8M (ASTM A351), and the seal material is PTFE (ASTM D4894). Material selection should consider chemical compatibility and temperature requirements.

What is the leakage rate and how is it measured?

The leakage rate is ≤0.01% of rated flow, meeting Class VI seat leakage. This ensures minimal leakage when the valve is closed. Verify the leakage class for your specific model with the manufacturer.
