Ny ventiltopp typ 8697

I kombination med lämpliga processventiler erbjuder 8697 en rad funktioner;
integrerad pilotventil med manuell manövrering, en LED-positionsindikator och
automatisk inställning av ändläget och återkoppling.

The Bürkert Type 8697 pneumatic control unit or position feedback is designed
for integrated mounting on process valves of the ELEMENT and CLASSIC series. The
devices are available in three versions: as a pneumatic control unit or position
feedback for ELEMENT valves with drive size 50, as a control unit for CLASSIC
valves with drive size 40/50/63 or as a position feedback, also for the CLASSIC
series with drive size 40 ... 225. When used as a control unit in combination
with ELEMENT or CLASSIC valves the Type 8697 now enables complete decentral
automation also for small drives. As a position indicator it replaces Type 1062
and features additional functions such as LEDs for indicating the device
The basic features of the Type 8697 include mechanical
self-adjusting valve position switches as 2- and 3-wire inductive or micro
switches. The switching condition of the end position detection is indicated by
LEDs on the device.
When used as a pneumatic control unit the 3/2-way pilot
valve with manual actuation is also integrated, eliminating the need for a
control cabinet with hoses leading to the respective valve. This simplifies the
system design and minimises the control air consumption for switching of the
Combination of the Type 8697 with a process valve of the ELEMENT
series results in an EHEDG-compliant valve system with high-level IP protection
and integrated control air supply with spring chamber ventilation. This solution
is ideal for cleaning-intensive and wet applications in the food and beverage
industry and in breweries.
