Schubert & Salzer develops new sliding gate valve

news item image
Valve specialist Schubert & Salzer Control Systems has developed a compact, lightweight and energy-efficient solution for all areas of the process industry with its new type 8028 sliding gate valve.
In addition, with a pneumatic 80-millimetre diaphragm actuator and digital positioner, the control valve allows for a low-noise operation.
The sliding gate technology used in the type 8028 controls the flow in milliseconds, whereby two slotted discs arranged vertically to the direction of flow slide over each another in a linear movement.
The required actuating force is 90% lower than globe valves with the same nominal size at the same differential pressure.
Schubert & Salzer Control Systems offers the type 8028 sliding gate valve in nominal sizes from 15 to 150 millimetres.
It controls media with temperatures from -60 to 350 °C and can be used at ambient temperatures from -30 to 100 °C.
The maximum operating pressure is up to 40 bar depending on the nominal size. The rangeability is 40:1 for linear and 80:1 for equal percentage flow.
All control valves made by Schubert & Salzer Control Systems are manufactured to order at the company’s headquarters in Ingolstadt.
The modular design of valves, actuators and positioners as well as a comprehensive, dynamically managed stock of primary materials ensure particularly quick delivery times.
