    • Long cycle life and maintenance-free operation
    • Flow-optimized stainless steel body
    • Multiple Kvs values per port size due to removable valve seats
    • Direct mounting of control units without external tubing

    Type 2301 - Pneumatically operated 2-way Globe Control Valve

    Type 2103 – 2/2-way diaphragm valve with pneumatic stainless steel actuator (Type ELEMENT) for decentralised automation

    The externally controlled Type 2103 diaphragm valve features a pneumatically operated piston actuator, a diaphragm, and a 2-way valve body. Its robust actuator, made with a stainless steel housing, ensures reliability in hygienic or aggressive environments. The flow-efficient valve bodies, designed with minimal dead space, support high flow rates and offer a wide range of applications. Both the valve body and diaphragm are available in various materials and configurations to suit specific needs. The actuator boasts a compact, autoclavable design with a large stainless steel housing and gap-free seals. Integration with ELEMENT automation units is possible at all configuration levels, including retrofitting, and a fieldbus interface can also be added. An explosion-proof ATEX/IECEx version is available. This compact, smooth-surfaced, and highly integrated system combines a valve and automation unit with built-in pilot air ducts (no intake of ambient air). The add-on body comes in plastic or stainless steel, with a 360° rotatable option. The valve offers IP65/67 and NEMA Type 4X protection, along with excellent chemical resistance.

    Key Features:

    • Valve body and diaphragm available in various materials and configurations
    • Wetted surfaces with Ra ≤ 0.38 µm…≤ 1.6 µm (optional electropolishing)

    Type 8692 - Digital electropneumatic positioner for integrated mounting on process control valves

    Type 8692 – Digital electropneumatic positioner for integrated mounting on process control valves

     

    The compact Type 8692 positioner is specifically optimized for integrated mounting on pneumatic actuators within the Type 23xx/2103 process valve series, designed to meet the stringent requirements of hygienic process environments. The pilot air duct is seamlessly integrated into the actuator, eliminating the need for external piping. User-friendly operation and the selection of additional software functions can be done through a large, backlit graphic display with a keypad or via the COMMUNICATOR. The positioner utilizes a contact-free, analog position sensor to accurately register valve positions without any degradation. Integrated diagnostic functions continuously monitor valve performance, and diagnostic messages are provided through status signals in compliance with NE107 (NAMUR), with historical data logging. The housing is easy to clean and constructed from durable, chemically resistant materials, making it ideal for hygienic applications in the food, beverage, and pharmaceutical industries. When combined with Bürkert ELEMENT actuators, the pneumatic actuating system ensures spring chamber aeration, preventing actuator contamination from the environment.

    FAQs

    • How do actuated valves work?

      In the past, people manually operated valves. This required someone to adjust the valve using a direct or geared mechanism attached to the valve stem. Additionally, it was also dangerous, especially when working with larger valves. However, actuated valves allow remote adjustment and rapid operation, keeping workers safe. Moreover, actuated valves have revolutionized the industry by providing remote control capabilities, thereby enhancing safety and efficiency.

    • What is a process control valve?

      Additionally, there are different types of process control valves. Ball valves can securely close after long periods of disuse; moreover, they can also be equipped with actuators. Butterfly valves, on the other hand, provide quick shut-off. Lastly, globe valves are ideal for high-pressure applications.
