S-Valve Assembly for Delivery Systems

Product Specifications

Technical details and manufacturing context for S-Valve Assembly

Definition

The S-Valve Assembly is a component used in delivery systems to regulate the flow of materials through an S-shaped passageway. It provides controlled discharge, metering, and directional flow management for various industrial applications. The assembly is typically constructed with a stainless steel body (equivalent to CF8M per ASTM A351) and a PTFE seat (per ASTM D4894) for chemical resistance. It is available in nominal diameters from 15 to 100 mm (ISO 6708) with flanged end connections (DN15–DN100, PN16 per ISO 7005-1). Operating pressure ranges from 1.0 to 1.6 MPa, and operating temperature is -20 to 80 °C. The flow coefficient (Cv) at full open is 5 to 120 US gal/min (ISA-75.01), with a leakage rate of ≤0.01% of rated capacity (Class VI per ISO 5208). Actuation torque required for manual or automated operation is 10 to 50 N·m. Weight varies from 2 to 15 kg depending on size and configuration. These values are reference ranges; verify model-specific data with the legal manufacturer or supplier. The assembly operates by rotating or actuating internal mechanisms to open, close, or modulate the S-shaped flow path, allowing precise control over material throughput while preventing backflow and maintaining system pressure. It is suitable for applications requiring reliable flow control in industrial delivery systems. Always confirm that the selected valve meets the specific process requirements, including pressure, temperature, and media compatibility, and that all relevant standards are verified for the intended use.

Working Principle

The S-Valve Assembly operates by rotating or actuating internal mechanisms to open, close, or modulate the S-shaped flow path. This action allows precise control over material throughput while preventing backflow and maintaining system pressure. The internal mechanism, typically a plug or ball, is positioned within the S-shaped passageway. When actuated, it either aligns with the flow path to allow passage or rotates to obstruct it, thereby regulating flow. The design ensures that the flow path is never fully straight, which helps in metering and controlling the discharge rate. The valve can be operated manually or automatically, with actuation torque ranging from 10 to 50 N·m. The PTFE seat provides a tight seal, contributing to low leakage rates. The S-shape also aids in maintaining pressure within the system, as the flow is directed through curves that reduce the risk of backflow. This principle is effective for applications requiring precise flow control and directional management.

Frequently Asked Questions

What materials are used in the S-Valve Assembly?

The body is made of stainless steel equivalent to CF8M per ASTM A351, and the seat is PTFE per ASTM D4894. These materials provide chemical resistance and durability.

What are the operating pressure and temperature ranges?

The operating pressure range is 1.0 to 1.6 MPa, and the operating temperature range is -20 to 80 °C. These are reference values; verify for your specific model.

What is the leakage rate of the valve?

The leakage rate is ≤0.01% of rated capacity, meeting Class VI seat leakage per ISO 5208. This ensures minimal leakage when the valve is closed.

How is the valve actuated?

The valve can be actuated manually or automatically, requiring an actuation torque of 10 to 50 N·m. The specific torque depends on the size and configuration.
