Product Description

Features and Benefits:

  • Dual Pattern ISO 5211 Direct Mount Pad
    No bracket or drive coupling needed for automation
    Eliminates exposed moving parts for safer work environment
    Direct drive eliminates play and improves actuator positioning
    Dual pattern pad fits a wide range of actuator sizes

  • High-Cycle, Live-Loaded Stem Packing
    Ensures tight seal
    Extends service life

  • O-Ring Stem Bearing
    Maintains stem alignment
    Reduces packing side loading and wear
    Enhances stem seal

  • Blow-Out-Proof Stem
    Stem is bottom loaded to prevent removal when valve is in service

  • Full Port Design
    Improves flow resulting in increased process efficiencies
    Facilitates cleaning of process lines without removing valve

  • 3-Piece Construction
    Easy to repair

  • Locking Device
    Enables plant personnel to secure valve in open or closed position when manually operated

  • Investment Cast
    Improves dimensional control and reduces porosity

  • End Cap Alignment Step
    Ensures easy and proper alignment between mating parts

  • Silver Plated Nut
    Reduces galling on threads

  • Heat Treated Ferrules
    Assures continuous tight seals

The 304C Compression Ends ball valve incorporates several innovative design features for improved process performance.  The uniform bore diameter improves flow rates and minimizes pressure drop through the valve.  The dual pattern ISO 5211 mounting pad facilitates direct mounting of pneumatic and electric actuators.  In combination with our high-cycle stem packing system, the 304F series ball valve provides an ideal choice for all your automation requirements.

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
