Valve Body / Housing: Temperature Range -29°C to 425°C

Component Specifications

Definition

The valve body or housing is the main structural component of the Apex Valve, serving as the pressure-retaining envelope that houses the internal closure mechanism (such as a ball, gate, or plug). It provides the flow path, connection points (flanged, threaded, or welded), and structural integrity to withstand operational pressures, temperatures, and mechanical stresses. Engineered for precise fluid control in pipelines, it ensures leak-tight sealing and compatibility with various media including water, steam, chemicals, and gases.

Working Principle

Acts as a pressure vessel that directs fluid through internal passages while supporting the valve's closure element. When the valve is actuated, the closure mechanism moves within the body to open, close, or modulate flow. The body's geometry (such as port design and flow coefficient Cv) determines flow characteristics, pressure drop, and sealing performance.

Materials

Typically ASTM A216 WCB (carbon steel), ASTM A351 CF8M (stainless steel 316), ductile iron ASTM A536, or brass C83600. Material selection depends on pressure rating, temperature range, and corrosion resistance requirements.

Frequently Asked Questions

What materials are used for Apex Valve bodies in corrosive environments?

For corrosive service, materials like stainless steel 316 (ASTM A351 CF8M), duplex stainless steel, or nickel alloys are specified based on media compatibility and NACE MR0175 standards.

How is pressure rating determined for valve bodies?

Pressure rating follows ASME B16.34, based on material strength, design temperature, and safety factors. Testing includes hydrostatic shell tests at 1.5x rated pressure.
