Description

3-Position Pneumatic Shutoff Ball Valve Assembly with Staged Anti-Water Hammer Protection

The VESON VSO-3P-WH 3-Position Pneumatic Shutoff Ball Valve Assembly is engineered specifically for batch loading terminals where abrupt valve closures cause destructive water hammer and piping vibration. The 3-position staged control delivers a smooth Fast Fill → Slow Dribble → Complete Stop sequence, protecting your piping system while maintaining precise dosing accuracy.

How 3-Stage Control Protects Your System

StageValve PositionAction
Stage 1100% OpenRapid bulk fill at full flow rate
Stage 230-50% Mid-StrokeSlow dribble feed for precise topping-off
Stage 30% ClosedBubble-tight shutoff (Class VI) - zero water hammer

Key Features

  • 3-Position Pneumatic Actuator: Spring-return design with mid-stroke position capability for staged flow control
  • Anti-Water Hammer Sequence: Eliminates pressure surges during valve closure, reducing pipe stress and prolonging system life
  • Configurable Mid-Stroke: Adjustable 30-50% intermediate position for process-specific flow rates
  • Bubble-Tight Shutoff: Class VI leakage at final closed position for zero product loss
  • Manifold Reduction: Replaces multi-valve manifold setups, reducing skid footprint and leak paths
  • Pre-Wired Solenoid Bank: Factory-configured solenoid valves for all 3 positions with terminal strip
