Control Valve Re-Design to Increase Productivity
This article has been supplied.
The entire Control Valve range of AZ-Armaturen has undergone a complete re-design with the excellent result of a modular system to increase productivity in the process, food, chemical and petrochemical industry. The construction of the Control Valves is based on the standard cavity-free plug valve with PTFE-sleeve or chemical resistant PFA/FEP-lining. Furthermore, a wide range of different materials are available for various applications. Heat Jacketed Control Valves are also available as well as different types of actuations such as pneumatic, electric and hydraulic systems. In case of a high flow velocity, a high pressure drop or solid-containing mediums, a protection insert can be added to increase the service life of the control valve.
AZ Control Valve with Electro-Pneumatic Positioner Cut-Away Control Plug Valve with Protection Insert
To control the pressure, flow or temperature as precisely as possible, 10 different plug forms are available per valve size, consisting of 5 linear and 5 equal percentage control characteristics. In case of very large flow rates, the full bore valve can be recommended and if there is a specific flow rate needed, the plug can be designed and manufactured according to the requirements. The AZ-Armaturen South Africa Team will gladly assist to choose the right system to increase control accuracy and productivity of the process and service life of the valve.
