Cyclonic WBD Series Wafer Style Choke Valve
Cyclonic has been setting the standard for precise and repeatable control of gases and liquids.
Cyclonic's WBD Series is a Wafer Style Choke Valve. Like all Cyclonic valves, the WDB Series is built with the Cyclonic Design Difference. When you need to control a wide range of pressures and flow rates of gases or liquids, Cyclonic’s superior design gives you accurate control and a long safe valve life.

Exclusive Side-Entry Design:
The valve design allows for a simple, one-man changeout of the tungsten carbide discs to reconfigure the valve for changed flow conditions.  Easily complete in-line inspection and maintenance critical for increasing safety and protecting the environment - all without taking the valve out of line, or removing the actuator.
