Plug valve Z33

pneumaticfor controlpetroleum

Control valves type Z33 (previous name: BR33) represent one of the valve designs, where change in flow ratio is achieved through an eccentrically set rotary plug. Such structures are particularly useful for control of flow under heavy-duty conditions, with high probability of cavitation and erosion. Possibility of obtaining high flows and a wide range of material and design variants make them ideal for application in many branches of industry, such as power generation, mining, metallurgy, chemical and petroleum industry, food industry, paper industry etc. We can adjust the control valve to match your individual needs. Body materials - carbon cast steel GP 240 GH (1.0619), WCB carbon cast steel for low temperatures G20Mn5 (1.6220) acid-resistant cast steel GX5CrNiMo 19-11-2 (1.4408), CF8M. Use of other materials is possible, but must be agreed upon. Non-catalogue products - We can adjust these parameters to your individual needs. In such cases, please contact our technical support specialist. In the menu: “Non-catalogue version control valves” and “New products” we present the following examples. one-piece valve body (cast with the throttle), except for the shaft sealing chamber, there are no static or dynamic seals the absence of a “tear-off” torque between the plug and the socket possibility of changing the KvS, without changing the plug or socket easy replacement of the rotationally symmetrical plug the extended throttle chamber allows the use of a double shaft seal that meets the “low emission” standard and meets the TA-Luft conditions the same KvS factors for “hard and soft” sockets
