Description

The Envalve butterfly valves are designed for shutting off or regulating flow. With an electric drive, they can be controlled remotely.
The butterfly valves are manufactured from pvc and have an EPDM annulus, which makes them resistant to many aggressive substances. The valves are also available with a VITON® annulus. The Envalve butterfly valves are designed for shutting off or regulating flow.

With an electric or pneumatic drive they can be controlled remotely. For operating the valve, the valve axle is connected to an electric driving motor. This driving motor has a supply voltage of 24VAC. On request, driving motors with a voltage of 230 volts can also be supplied. The driving motor can rotate in two directions and is controlled by the phase of the supply voltage.

Type VK11: 1 valve - 1 engine
Type VK21: 2 valves - 1 engine
