Water Flow Regulators

---

Worldwide Approved, WITTMANN Water Flow Regulators Have Long Been an Industry Standard. WITTMANN water flow regulators have established the company's good reputation. Today, they are essential for the plastics processing industry.

The proven technology from WITTMANN, refined and in a new setting. Standard equipment in every injection molding machine for more than 40 years. Often copied, never equaled. With over 500,000 appliances sold the uncontested number 1!

Different Series for Different Applications

Series 110 and 310: flow rates up to 10 or 30 l/min per circuit

Series 200/230 brass water flow regulator

Series 401: flow rate up to 8 l/min per circuit

For the flow control of multiple circuits the WFC is a flow controlling device with maintenance-free Flow Measuring System – selectable between a max. temperature of 100 °C and a max. temperature of 180 °C.

Standard Equipment

Remote control with 7-segment display with actual value display.

Flow monitoring for up to 8 circuits.

Serial interface (20mA, RS232, RS485).

Isolated alarm contact.

Mounting angle.

External sensor PT 100 (for WFC 180).

With its proportional valve and zero-wear flow measurement, the WITTMANN Flowcon plus ensures constant flow and a constant temperature, all achieved in reproducible fashion through the whole period of manufacture.

The Flowcon plus achieves permanent monitoring of the amount of fluid passing through a cooling duct, which gives it a decisive advantage. Disruptive factors, such as constriction of cooling ducts or fluctuations in pressure are detected and the flow is controlled proportionally using stepper motors instead of the old manual regulating valves. This prevents irregularities in the temperature and improves the safety of the process, which ultimately contributes to a superior quality of components. All of the process data can be saved and very easily called up for subsequent production runs. The Flowcon plus water flow controller also makes it possible to connect 4 x 12 circuits together by means of data cables.
