Component Specifications

Definition
The Head Housing is a precision-engineered structural component that forms the outer protective shell of a diaphragm head assembly in industrial machinery. It serves as the primary mounting platform for internal components including the diaphragm, valve mechanisms, and actuation systems while providing environmental protection, pressure containment, and structural support. This component is designed to withstand operational stresses, maintain alignment of internal parts, and ensure proper sealing for fluid or gas handling applications.
Working Principle
The Head Housing operates as a stationary structural element that contains and protects the dynamic components of the diaphragm head. It maintains pressure integrity by providing a sealed environment for the diaphragm's reciprocating motion, transfers operational forces to the machine frame, and ensures proper alignment of the valve seat and actuation mechanism. The housing's design allows for controlled fluid or gas flow while preventing leakage and external contamination.
Materials
Typically manufactured from cast iron (ASTM A48), ductile iron (ASTM A536), stainless steel (AISI 304/316), or aluminum alloys (6061-T6) depending on application requirements. Materials are selected based on pressure ratings, corrosion resistance, and compatibility with processed media.
Technical Parameters
  • Surface Finish Ra 3.2 μm or better
  • Pressure Rating Up to 300 psi (20.7 bar)
  • Mounting Standard ANSI/ASME B16.5 flange patterns
  • Temperature Range -20°C to 150°C
  • Dimensional Tolerance ±0.1 mm
Standards
ISO 5211, DIN 3337, ASME B16.34
