Drain/Outlet Port with Valve

Product Specifications

Technical details and manufacturing context for Drain/Outlet Port with Valve

Definition

A drain/outlet port with valve is a critical component of waste collection vessels that provides a controlled means for emptying collected waste materials. It consists of a port opening integrated with a valve mechanism to regulate flow, prevent leaks, and maintain containment integrity during operation and maintenance cycles. The valve mechanism (typically ball, gate, or butterfly type) opens or closes to control the flow of waste material through the port. When closed, it seals the vessel; when opened, it allows waste to drain through the port under controlled conditions, often using gravity or pressure differentials. This component is used in industrial machinery and equipment manufacturing, particularly in systems where waste collection and disposal are necessary. The port is available in nominal diameters from 15 to 100 mm (ISO 6708), with operating pressures from 1.0 to 1.6 MPa. Operating temperature ranges from -20 to 120 °C, limited by seal material. Leakage rate is Class A for metal-seated valves (0–0.1 mL/min per ISO 5208). Flow coefficient (Cv) ranges from 2.5 to 120, depending on port size and valve design. Body material is typically stainless steel 304 or 316 (ASTM A351), with 316 recommended for corrosive media. Seal materials include PTFE for chemical resistance and EPDM for water applications. Connection types are threaded up to DN50 and flanged above (GB/T 9113). Weight varies from 0.5 to 15 kg. Actuation can be manual for small sizes or pneumatic for automation. These parameters are reference ranges; actual values must be confirmed with the manufacturer for specific models and applications. Standards listed are for verification and procurement reference only, not certification. Always verify model-specific values and standards with the legal manufacturer or supplier.

Working Principle

The valve mechanism, typically ball, gate, or butterfly type, opens or closes to control the flow of waste material through the port. When closed, it seals the vessel to prevent leaks and maintain containment. When opened, it allows waste to drain under controlled conditions, often using gravity or pressure differentials. The valve can be actuated manually or pneumatically, depending on the size and automation requirements. The port is designed to integrate with the vessel's outlet, ensuring a secure connection and reliable operation.
