Ball valves — Selection and installation guide
Design and application checks
A ball valve rotates a bored ball to isolate or divert flow. Selection depends on ball support, port arrangement, seat material, end connection and actuation; not every ball valve is designed for throttling.
In a floating design the ball can move slightly toward the downstream seat under differential pressure. A trunnion-mounted ball is supported by shafts or trunnions; sealing depends on the seat design rather than free movement of the ball. Confirm torque and differential-pressure limits for the actual design.
What should I provide for a quotation?
Provide the fluid and composition, solids content, normal and design pressure and temperature, DN or NPS, connection standard, installation orientation, operating duty and required inspection documents. State any corrosion, vacuum, fire-safety or emissions requirements separately.
How do I confirm the pressure and temperature rating?
What must be checked before installation?
Compare the face-to-face dimension, flange drilling and facing, pipe bore, flow direction and maintenance clearance with the approved drawing. Clean and isolate the pipeline, release pressure and follow the product installation instructions. Do not use flange bolts to pull misaligned pipework into position.
