Technical details and manufacturing context for Delivery Manifold & Valves

Definition

The Delivery Manifold & Valves is a critical component within the Resin Storage and Delivery System, responsible for precisely routing and regulating the flow of liquid or molten resin from central storage tanks or containers to various points of use, such as injection molding machines, extruders, or coating applicators. It ensures controlled, leak-free distribution and allows for isolation of individual lines for maintenance or process changes. The manifold acts as a central hub with multiple outlet ports. Valves (typically ball, gate, or needle valves) installed at the inlets, outlets, or within the manifold body are manually or automatically actuated to open, close, or throttle the flow. This creates a configurable flow path network, enabling operators to select which delivery line is active, control flow rate, and shut off sections of the system. The unit is available in nominal diameters from DN25 to DN100 (ISO 6708), with an operating pressure range of 1.0 to 1.6 MPa. Flow rates typically range from 10 to 100 L/min, depending on viscosity and pressure drop. Operating temperature is -40 to 85°C, with seals degrading above 85°C. Leakage rate is ≤0.1 mL/min (Class A shut-off). Body material is stainless steel CF8M (ASTM A351), and seal material is PTFE (ASTM D4894). Actuation can be manual, pneumatic, or electric, with a control signal of 4-20 mA (IEC 60381) for proportional control and a supply voltage of 24 V DC ±10% for solenoid pilot. Enclosure rating is IP65 (IEC 60529). Weight ranges from 5 to 20 kg depending on size and configuration. Always verify model-specific values and standards with the legal manufacturer or supplier before procurement.

Working Principle

The manifold serves as a central distribution hub with multiple inlet and outlet ports. Valves, typically ball, gate, or needle types, are installed at strategic points within the manifold body or at the ports. These valves can be manually operated or automatically actuated via pneumatic or electric systems. By opening, closing, or throttling the valves, operators create a configurable network of flow paths. This allows selection of active delivery lines, adjustment of flow rates, and isolation of sections for maintenance or process changes. The system ensures controlled, leak-free distribution of resin from storage to processing equipment.

Frequently Asked Questions

What materials are used for the manifold body and seals?

The body is made of stainless steel CF8M (ASTM A351), and the seals are PTFE (ASTM D4894). These materials provide corrosion resistance and chemical compatibility for resin handling.

What are the operating pressure and temperature ranges?

The operating pressure range is 1.0 to 1.6 MPa. The operating temperature range is -40 to 85°C, with seal degradation above 85°C.

How is the manifold actuated?

Actuation can be manual, pneumatic, or electric. For proportional control, a 4-20 mA control signal (IEC 60381) is used, and for solenoid pilot, a 24 V DC ±10% supply voltage is required.

What is the leakage rate and enclosure rating?

The leakage rate is ≤0.1 mL/min, meeting Class A shut-off. The enclosure rating is IP65 (IEC 60529), providing dust-tight and water-jet protection.
