| 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
- a leakage rate of less than 0.01% KvS for “hard” sockets (“metal-to-metal”)
- same flow direction for “hard” and “soft” sockets
- an externally accessible connection between valve and actuator, allowing the actuator to rotate relative to the valve in 90° increments
- possibility of special versions: with a heating jacket, with anti-erosion properties, for crystallizing media
We can adjust the control valve to your individual needs. In such cases, please contact our technical support specialists.
