Product Description

Features and Benefits:

  • High-Cycle, Live-Loaded Stem Packing
    Dynamic loading on stem packing ensures a tight seal through varying pressure and temperature conditions, reducing maintenance costs and extending service life
  • End Cap Alignment Step
    Ensures easy and proper alignment between mating parts

  • Full Port Design
    Improves flow resulting in increased process efficienciesl

  • 3-Piece Construction
    Easy to repair

  • Blow-Out-Proof Stem
    Stem is bottom loaded to prevent removal when valve is in service
  • Locking Device
    Enables plant personnel to secure valve in open or closed position when manually operated

  • Investment Cast
    Improves dimensional control and reduces porosity

  • Silver Plated Nut
    Reduces galling on threads

  • Heat Treated Ferrules
    Assures continuous tight seals

The 302C Compression Ends ball valve delivers exceptional performance and economy in a 3-piece design. Full porting improves flow rates and minimizes pressure drop through the valve. Our unique metal-backed seat design enhances overall valve performance while our live-loaded stem packing automatically adjusts for wear and thermal variations.

Operating / Test Conditions:

  • Temperature Range (RTFE seats): -20 to 420 F

  • Maximum Working Pressure (RTFE seats): 
    1000 PSI CWP (1/4" - 1")

  • All valves shell and seat tested to ANSI/ASME B16.34 and API 598
  • All materials comply with applicable ASTM material specifications

Options:

  • End connections available in NPT, socket weld, Sch. 5/10/40 butt weld, grooved, and ANSI Class 150 and 300 flanged in 316SS or carbon steel

Assembly and Reassemble Instruction

Assembly Instruction

1. Insert the tubing until it rests against the counter bored pipe end

2. Be sure the nut is finger tight, then tighten with wrench an additional 1-1/4 turn

Reassemble Instruction

1. Insert the tubing end with the previously set ferrules into the pipe end

2. Tighten nut by hand. Rotate nut to the original position with a wrench. (An increase in resistance will be encountered at the original position) Then tighten slightly with the wrench
