Product description
5 PRODUCT DESCRIPTION
The device is specially optimised for decentralised process automation and meets all the relevant requirements, even under difficult usage conditions.
Its design enables the easy integration of automation modules in all extension stages, whether they are
electrical/optical position feedback, pneumatic control units, or even an integrated fieldbus interface. Long
service life and high tightness are achieved by the tried and tested self-adjusting packing gland. The system, consisting of valve and automation module is distinguished by a compact and sleek design, integrated
pilot air ducts, a high chemical resistance, the degrees of protection IP65 or IP67 as well as the NEMA protection class 4X.
The device uses neutral gases or air to control the flow rate of liquid or gaseous media, such as water, alcohol, oil, fuel, saline solution, lye, organic solvent or vapour.
5.1 Features
▪ Body made of stainless steel with threaded connection, clamp connection or welded connection
▪ Easy integration of automation modules
▪ Actuator can be rotated steplessly by 360°
▪ High chemical resistance
▪ High flow values through flow rate-optimised valve body made of stainless steel
▪ High seat tightness by swivel plate
▪ Integrated pilot air duct in combination with a Bürkert automation module
▪ High tightness and long service life due to self-adjusting packing gland
▪ Maintenance-free under normal conditions
5.2 Structure and function
The device consists of a pneumatically actuated piston actuator and a 2-way valve body. The actuator is
manufactured from polyphenylene sulphide (PPS). Valve body and actuator housing made of stainless steel.
Spring force or pneumatic pilot pressure generate the closing force on the swivel plate. The closing force is
transferred by a spindle connected to the actuator piston.

5.2.2 Flow direction below seat
WARNING!
Valve seat leaking when control pressure is too low or medium pressure is too high.
If control pressure is too low for control function B and control function I or medium pressure is too high,
the valve seat may leak.
▶ Observe values for minimum control pressure and maximum medium pressure.
Depending on the control function, the valve closes by spring force (control function A) or pilot pressure
(control function B and I) against the medium flow.
As the medium is present under the swivel plate, the medium pressure contributes to the opening of the
valve.
Fig.2: Flow direction below seat, valve closes against medium flow
5.2.3 Flow direction above the seat
DANGER!
Risk of injury from rupturing lines and device when flow direction above the seat.
A pressure surge of liquid media may cause the lines and device to rupture.
▶ Do not use valves with flow direction above the seat for liquid media.
Flow direction above the seat is possible only on valves with control function A (closed by spring force in
rest position)1.
The valve closes by spring force with the medium flow. As the medium is present above the swivel plate,
the medium pressure contributes to the closing of the valve. The medium pressure also supports the sealing of the valve seat.
The valve opens by the pilot pressure.

5.3 Variant 3-position actuator
With the 3-position actuator the valve can have a middle position. This variant is available only in control

Product description
Fig.4: Variant 3-position actuator
The closing force on the swivel plate is transferred by a spindle. The spindle is connected to the actuator
piston.
Middle position
The middle position corresponds to a specific, adjustable flow rate of the medium. It is reached by an additional piston in the upper part of the actuator. The middle position is set with a nut (see figure).
The additional piston is used as a stop for the actuator piston. If pilot air port 2 is pressurised, the additional
piston moves downwards to the set position. If pilot air port 1 is then pressurised, the actuator piston
moves upwards until it hits the additional piston and stops.
Maximum stroke
If the upper air chamber is vented by pilot air port 2, both pistons move upwards. As a result, the maximum
stroke is reached.
Closing the valve
If the lower air chamber is vented by pilot air port 1, the spring force acts on the actuator piston. The spring
force moves the actuator piston downwards until the valve is closed (rest position).
