Steel Valves

Typical applications:  Steel valves are primarily used in commercial, industrial, and automotive applications.

Valve Types:

  • Compression Packed
    • Temperature resistance
    • Replaceable seal
  • O-ring Crimped
    • Economical
    • Does not require adjustment
  • O-ring Packed
    • Seal may be installed after valve installation avoiding risk of damage from heat generated during solder connection to system
    • Replaceable seal

 Advantages of Steel

  • Economical (typically 30%-40% less than Brass)
  • Variety of connection types
  • Variety of valve sizes
  • Variety of configurations
  • Available finishes
    • Copper
    • Nickel
    • Tin – most economical, typically painted by end user
    • Zinc – maximum corrosion protection (500 hr salt spray), ideal for mechanical connection applications
  • UL Recognition

Brass Valves

Typical applications: Brass valves are typically used in consumer or residential applications as well as applications where corrosion resistance is of greater importance such as truck trailer refrigeration, container refrigeration and transport air-conditioning.

Valve Types

  • Non-Back Seating
    • Economical
    • Maximum flow
    • Minimum pressure drop
    • Valve core process port
    • Hex wrench actuation
    • Field replaceable stem
    • O-ring Seal
  • Back Seating
    • Full flow gage port / Serviceability
    • Conventional valve wrench actuation
    • Additional secondary seal to atmosphere
    • Compression Packed Seal

 Advantages of Brass

  • Corrosion Resistance
  • Availability of stainless steel connections
  • UL Recognition
