EDV Valve Tray


Valve trays are widely applied in petrochemical and alcohol industry for columns ranging from 0.5m to 10.2m in diameter, from 170mm to 1100mm in tray spacing, from single-flow to six-flow in design, and from a couple of pcs. to 200pcs in quantity. The major advantages of these valves trays are: efficient mass transfer in large range of workloads, simple design, low content of metal and low cost.

A new high efficiency type of valve trays design is based on traditional trays. It features improved design of a valve and a tray as a whole, increased capacity, efficiency and operation flexibility.

1. Non-revolving Valve with Top Protrusions

Top protrusions make vapour dispersion more uniform and fine, which improves efficiency. The anti-spin valve hole prevents valve rotating like V1 valve, and valve falling from the hole, which occurs when the valve legs become overly worn.

2.“Quick-Connect” Active Tray Joint

The patented "Quick-Connect" active tray joint allows easy on-site installation and eliminates inactive tray zones typical for all other trays. This creates a more “effective active zone” and eliminates liquid bypass.

3.Inlet Bubble Promoter

The EDV® tray has a unique inlet bubble promoter to allow froth initiation near the inlet area of the active panels. The froth initiation helps to minimize or eliminate liquid gradient on the tray and promotes uniform froth distribution across the entire tray active area. This results in higher tray capacity and operating flexibility.

4. New-Design Downcomer

New-design downcomer with directional flow promotion helps to eliminate stagnant liquid pools on the tray and promotes uniform liquid penetration and froth density across the entire bubbling area. Directional flow promotion prevents fouling material settling on the tray deck and extends the column run time.

EDV® Tray List

EDV® Valve Tray (EDV®) 1. EDV® Valve Tray (EDV®)
  • Floating round valve with top protrusions for fine dispersion
  • High efficiency, capacity, and operating flexibility
  • For wider operating flexibility, heavy EDV® valve (EDV®-H ) can be used together with EDV®



EDV® Rectangular Valve Tray (EDV®-R) 2. EDV® Rectangular Valve Tray (EDV®-R)
  • Floating rectangular valve with top protrusions for fine dispersion
  • Directional EDV®-R valve (EDV®-RD) can be used in conjunction with EDV®-R for directional flow promotion using a directional valve leg
  • For more flexible operation, heavy EDV®-R valve (EDV®-RH ) can be used together with EDV®-R



EDV® Fixed Valve Tray (EDV®-F) 3. EDV® Fixed Valve Tray (EDV®-F)
  • Fixed valve tray with three top protrusions for fine dispersion
  • More flexible and efficient than a conventional sieve tray
  • Suitable for fouling and coking systems
  • Non-top (EDV®-F0) or one-top (EDV®-F1) protrusion valve is available for different operational needs



EDV® Rectangular Fixed Valve Tray (EDV®-FR) 4. EDV® Rectangular Fixed Valve Tray (EDV®-FR)
  • Fixed valve tray with three top canopies for fine dispersion
  • More flexible and efficient than a conventional sieve tray
  • Suitable for fouling and coking system
  • Single top protrusion valve (EDV®-FR1) is available for different operational needs



EDV® Combinatorial Valve Tray (EDV®-C) 5. EDV® Combinatorial Valve Tray (EDV®-C)
  • Combinatorial valve with a fixed round valve as the base valve and a floating round valve as the top valve
  • Top valves close in the case of low vapor loading. This allows the tray operate more flexibly
  • Combines the advantages of a fixed valve tray and a floating valve tray. It is flexible and has high mass-transfer efficiency
  • Suitable for fouling and coking system



EDV® Rectangular Combinatorial Valve Tray (EDV®-CR) 6. EDV® Rectangular Combinatorial Valve Tray (EDV®-CR)
  • Combinatorial valve with a fixed trapezoidal valve as the base valve and a floating rectangular valve as the top valve
  • Top valves close in the case of low vapor loading. This allows the tray to operate more flexibly
  • Combines the advantages of a fixed valve tray and a floating valve tray, It is flexible and has high mass-transfer efficiency
  • Suitable for fouling and coking system



Scalloped EDV® Valve Tray (EDV®-S) 7. Scalloped EDV® Valve Tray (EDV®-S)
  • Floating round valve with scalloped lace and top canopies
  • Vapor jets from side scalloped lace and top canopies for fine dispersion and to reduce pressure drop
  • The valve hole of EDV®-S is smaller than that of a conventional valve. This makes EDV®-S especially suitable for low-vapor scenarios where high efficiency is required
  • With EDV®-SH round heavy valve, a Scalloped EDV® valve tray operates higher capacity and flexibility
