- Valve cluster ready for installation Compact design without any potential leakage No assembly effort No piping between the valves needed Trusted actuators for simple automation Type 8840 comes with ready to install modules of tried and tested Bürkert process valves. The valve cluster, based on a modular valve body, allows different configu rations. The individual parts are joined hermetically tight and in a very compact way. No installation effort for pipework, fittings or sealings is needed. For the sizes DN 20 (¾") and DN 25 (1") orbital welding is used. The smaller variants in DN 10 are threaded together using trusted graphite seals. To avoid dangerous water hammer, all valves have the flow direction below the seat. This is made possible by the two variants for the fluidic main function distribution and collecti ng, mixing or feed. Depending on the requirement and preferred type of automation, it is possible to choose from different actuator variants. The robust CLASSIC actuators (in stainless steel or plastic) are controlled by a central valve island or by a pilot valve. The proven ELEMENT actuators allow a simple decentralized automation by using intelligent control heads Furthermore it is possible to expand the system by using continuous control valves, sensors, customer specific pipework or further acces- sories. Product variants described in the data sheet may differ from the product presentation and description. Type description Can be combined with Type 8840 © Christian Bürkert GmbH & Co.

Product accessories Electrical position indicator Control head Type 8691 Actuator size Ø 70 mm The control heads Type 8691 and Type 8695 are optimised for integrated mounting on process valves of the 21XX series. The valve position is detected without contact via an analogue sensor element. The sensor element automatically detects and stores the valve end positions during commissioning using the teach function. The integrated pilot valve controls single-acting or double-acting actuators. The valve switching status is indicated by coloured high-performance LEDs.

Modular platform for process control and regulation Combination options based on Type 8840 Note: Individual customer solutions available on request Type 8840 enables Bürkert to provide quickly and efficiently all common valve assemblies for distributing and collecting functions already in the pre-configured state (for other possible variations, see “4. Dimensions” on page 9 ). Furthermore, individual customer solutions are available on request. Thanks to the modular platform for process control and regulation, various application-specific requirements can be met. The modular platform for process control and regulations also enables every combination option when selecting the actuator, control and measuring principle and the fluid functions: Actuator variations: Electromotive, pneumatic, manual Control, regulation principle: On/Off, continuous Sensor variations: Temperature, pressure, flow rate Irrespective of whether the system is to be actuated by an electric motor, pneumatically or manually, Bürkert offers the ideal actuator and control/regulation principle for every requirement. Moreover, the ideal measuring principle can be selected from the extensive sensor range for measuring temperature, pressure and flow rate. They guarantee reliable measurement values and can be easily integrated into the system. Besides the standard distributing and collecting functions, specified fluid combinations can be achieved.
