- Each Dpu Consists Of A Bellows Unit Assembly (Bua) And Removable Pressure Housings.
- Within The Bua, Flexible Bellows Are Secured To A Centerplate.
- In Dual-Bellows Models, The Movable Bellows Are Rigidly Connected By A Dual Valve Stem That Passes Through The Centerplate.
- Valve Seats, In The Centerplate Passage, Form A Seal With The Valves.
- Contacting The Valve Stem In The Centerplate Is A Drive Arm Pivoted On The End Of A Sealed Torque Tube.
- The Bellows Is Filled With A Clean, Noncorrosive, Low-Freezing Point Liquid.
- A Range Spring Assembly Provides Tension Against Applied Pressures.
- In Operation, Pressure Is Applied To Both Sides Of The Bellows. Any Difference In Pressure Causes The Bellows To Move Until The Spring Effect (Range Springs) Balances Out The Force.
- The Linear Motion Of The Bellows (Proportional To The Dp) Is Transmitted As A Rotary Motion Through The Torque Tube. In Dual-Bellows Units, If The Bellows Are Subjected To A Dp Greater Than The Unit S Dp Rating, A Valve Closes And Traps The Fill Liquid In The Bellows Fully Supporting The Bellows And Preventing Rupture.
- Since Opposing Valves Are Used, Full Protection Is Provided In Either Direction.
