Reversal Valve - An Important Component of EQB System | Eqobrush

Reversal Valve As An Important Component of EQOBRUSH System

Eqobrush automatic brush tube cleaning system prevents fouling or scaling in the tubes of heat exchangers, chiller condensers or steam condensers by means of brushes flowing through each tube and reversal valve that, actually, makes the backflushing possible

Special Reversal Valve - Swing-Box

Eqobrush reversal valve patent certificate

Eqobrush designed a special reversal valve called Swing Box. It was intelligently engineered by WATCO Group team and received a patent for this innovation.

What is Reversal Valve

Reversal Valve is used to reverse or change the flow in the tubes of the equipment, usually heat exchangers and chiller condensers. The switch of the flow can be done manually and automatically on a regular basis, by programming the schedule according to the needs of your operation.

Requirements for the System

Reversal Valve can be used in any system that meets these requirements

Size of the Tubes

Nominal size of the tube (from 80 mm to 600 mm) [KV80 – KV600 types of Valves]

Flow Rates

Nominal flow rates (from 50 m³/h to 3000 m³/h)

_______________________________________________________
For larger nominal sizes or flow rates, the flow direction will be reversed using Butterfly Valves.

Pressure Level

The standard units of Swing-Box are designed for operation pressures of 10 bar [PN6 -PN10-PN16 types of Valves]

Cooling Water Temperature

maximum of 50°C

In accordance with the actual operation conditions and water quality, the units will be manufactured of:
– construction steel inclusive coating (standard design)
– stainless steel

heat exchanger cleaning

Advantages of Reversal Valve

The swing box is a solution to many problems and is successfully applied in all Watco reversing valves
  • Flow openings in the reversal valve are never smaller than the pipe flow surface
  • Also there are no loops in the water flow. This addresses the issue of pressure loss
  • The cross-over problem is also solved since the swing-box does not need any clearance to complete its runway
  • There are no gaps for water to leak
  • The clearance is not needed as all contact surface is in the same horizontal pane that are guarded by Teflon rings
