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 areelectrical/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, hydraulic fluid, lye, organic solvent or vapour.

5.1

Features▪ Actuator can be rotated steplessly by 360°
▪ Stainless steel valve body
▪ Easy integration of automation modules▪ High chemical resistance▪ High tightness and long service life due to self-adjusting packing gland▪ High flow values through flow rate-optimised valve body made of stainless steel▪ High seat tightness by swivel plate▪ Maintenance-free under normal conditions

5.2

Structure and function

The angle seat valve consists of a pneumatically actuated piston actuator and a 2-way valve body. The actuator is made of PA or PPS. The proven, self-adjusting packing gland guarantees a high degree of tightness. Valve bodies made of stainless steel or red bronze 1.
Depending on the variant, the valve seat is connected in the direction of or against the medium flow. Springforce (SFA) or pneumatic pilot pressure (SFB and SFI) generate the closing force on the swivel plate. A
spindle connected to the actuator piston transmits the force.

5.2.1

Flow direction below seat

WARNING!
Valve seat not sealed when control pressure too low or operating pressure too high.
If control pressure for control function B and control function I is too low or operating pressure is too high,this can cause the valve seat to leak.
▶ Comply with minimum control pressure and maximum operating pressure values.
Depending on the control function, the valve closes by spring action (control function A) or pilot pressure(control function B and I) against the fluid flow.
As the medium is present under the swivel plate, the operating pressure contributes to the opening of thevalve.

5.2.2

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 action in
rest position).2.
The valve closes by spring action with the fluid flow. As the medium is present above the swivel plate, theoperating pressure contributes to the closing of the valve. The operating pressure also supports the sealingof the valve seat.
The valve opens due to pilot pressure.
