« SAK » stands for « Silo-AustragsKegel » , which means in English « Extraction cone valve for silo». The SAK is designed to control the discharge of powder or granulates out of silos.
The SAK is particullarly efficient in the following cases:
- For a « fast » silo discharge (high extraction capacity)
- For dosing the discharged powder or granulate
- For discharging a silo at different flow
- Garanty a proof closing of the silo (self closed without energy)
- For extracting and discharging “difficult” flowing powders
Working Principle:
- The cone valve is guided in a hopper located at the bottom of the silo
- The cone valve is lifted by a pneumatic bellows
- The adjustment of the opening is set by the stroke of the guiding rod one for all (basic version)
- The continuous adjustment is set by a pneumatic drive adjusting the stroke from 0 to 100% (dosing version)
- Dosing of the discharged product by adjustment of the opening of the cone valve versus the weight on scale, through an interface terminal IT 9000.
- Vibration of the cone in open position

The automation of production equipment and processes with the aid of electronic regulation and control equipment requires interfaces between the electronic and fluidic control loops.
The valve described below for regulating the flow rate of liquids and gases represents such an interface. Fluids are mainly delivered and isolated by solenoid actuated on-off valves. However, the way they and manually actuated throttle valves operate does not meet certain flow requirements. Therefore, wherever exact adjustment to the actual requirement is needed, one of the wide range of motorised valves on offer is used. Depending on the application and accuracy required, it is possible to chose between an extremely wide variety of control element and drive design principles.
This is a rotary valve, with two oxide ceramic throttling discs which resist dirt and do not wear.
The maintenance free electrical servodrive consists of powerful reversible motors; with a choice between DC, synchronous and stepper designs to suit the type of control system available.
The backlash free gearing, which is positively connected to the drive shaft in order to rotate the control disc, guarantees a reproducible defined control characteristic. The limit - i.e. valve closed or fully open - is detected by two separate, floating microswitches. As a result of the low power consumption of between 1.5 and 5W, the electronic regulator can operate certain types of motor directly.

507V:
Incorporated in the disc edge are vane-like teeth which are set at a critical angle. The valve displays superb control characteristics. The teeth around the disc edge break down the fluid energy acting on it with a resultant reduction in pressure recovery. The gull wing-like disc profile touches the seat at a pre-determined angle which results in greatly reduced seating/break out torque.
508V:
Incorporates the gull wing and toothed disc edge features of the 507V, but with an integral EPDM rubber seat which includes the proven cosine curve seating features.
The use of the rubber seat ring eliminates the need for an expensive additional stop valve. The 508V seat ring is built around a metal core ensuring stability whilst the valve is working under control conditions.
Face-to-face dimensions are to ISO5752 basic series 20.

2/2 Way Pneumatically Operated Diaphragm Valve with Stainless Steel Body, DN 4-100
|
|
This type of valve is actuated by pressure acting on a piston or diaphragm. The fluid is usually neutral e.g. air, water, hydraulic oil. The pressure range varies and is specified accordingly in a data table.
"Normally Closed" (N/C) valves of this type remain closed under spring pressure, when de-activated.
"Normally Open" (N/O) valves of this type remain open under spring pressure, when de-activated.
When pressure is connected to port "Z" the valves open or close according to type.
A separate 3/2 pilot valve is used to supply pressure to port "Z", it is mounted either directly on the actuator or remotely.
In some cases a 4/2 or 5/2 pilot valve will be required. The main valve position can be N/C or N/O. The basic position is determined by connecting the pilot valve output lines accordingly. (The direction of flow is usually indicated by an arrow or shown schematically on the body).

Diaphragm Valves - Rotoflex
The Rotoflex lends itself particularly on filling applications. The sleeve is fixed with clamping rings. It can also be used on in-line systems but care must be taken to ensure mating gasket or flange does not interfere with rotating clamping ring.
The Flexible sleeve valve has proved itself over a number of years as a simple, reliable isolation or variable feed control valve on applications in the powder or air handling industries - its simplicity being its major advantage.
The basic construction is a rubber sleeve that, with each end being held firmly to a circular shape on rotation through 180°, will completely seal against the very finest of powders and limited air pressure.
Partial rotation leads to partial opening and a multitude of different types of sleeve can be accommodated, the better type of sleeves are food quality nylon, impregnated cloth and wear resistant natural rubber. These types of sleeves are weighty, give the valve good full opening properties and are dust tight.
