PSG Slide Gates are used to intercept or cut off the flow of powders or granulates. Their rugged construction makes them ideally suited for heavy-duty applications in diverse industries.
To ensure sanitary operation in food plants and maximum protection of the valve, the blade is equipped with a double seal.
PSG Slide Gates are available with hand wheel or pneumatic actuator. The gates can be ordered in powder coated carbon steel (light grey color, RAL 7035), or in all stainless steel construction.
They provide reliable trouble free operation within your production processes.

ppg (pneumatic positioning GATE)
PPG Slide Gates are used to meter (or cut off) the flow of free flowing powders or granulates in accurate repeatable percentage increments, permitting accurate volumetric blending of these products.
Their rugged construction makes them ideally suited for heavy-duty applications in diverse industries, including grain processing, plastics, seed handling, etc.
To ensure sanitary operation in food plants, and best protection of the valve, the blade is equipped with a double seal.
PPG Slide Gates are available with a pneumatic actuator system. The gates can be ordered in powder coated carbon steel (finish light grey color, RAL 7035), or in stainless steel.
Constant volumetric metering system for free-flowing products for continuous volumetric blending for volumetric addition of ingredients for attaining volumetric target quantities and throughputs with maximum accuracy and distinctive product quality advantages within your production processes.
Operation
The PPG is attached either directly or by means of spouting to a bin or hopper. The product is fed from the bin or hopper to the inlet (1). A pneumatically controlled slide gate (2) meters the stream of product at the slide opening selected, expressed as a percentage. The on board electronics (3) monitors and controls the slide position with the aid of the (patented) control valve (4) through the pneumatic cylinder (5). The current slide position is registered by a linear position sensor (6), which transmits it to the on board controller. The required slide position is specified directly at the unit, or by remote control through a process control system using an appropriate serial or analog (option) interface signal.
