Rotary switches - Import export

The Rotary Selector Valve or RSV, is a small bore multiport, multibank rotary poppet system suitable at pressures ranging –1 +10 Bar, Fluid Temperature 85°C (185°F) . It is a relatively simple & therefore extremely reliable unit, based on a modular design & as such configurable for a multitude of applications. It is custom built from stock parts. The body is manufactured in brass or stainless steel, both having stainless spindles & they can have stems and seals in differing materials to suit the media being used. Each bank of the valve is pneumatically independent but linked by a common central spindle, enabling separate air paths to be controlled concurrently; each output is effectively a valve. The RSV (once also known as the PIV or Pneumatic Interlok Valve) can incorporate an integral electrical rotary switch which allows fluid & electrical circuits to be controlled simultaneously or can be used simply to provide positional indication remotely at the control centre.

The Rotonivo® rotary paddle level switch from UWT operates reliably and maintenance-free and offers a compatible solution for plants for safe level detection in bulk solids. It has all current international approvals for use in gas and dust explosive atmospheres and is one of the first rotary vane detector certified according to SIL 2. Overfill protection and no-load protection are guaranteed for the long term. The three Rotonivo® rotary paddle level sensor series RN 3000, RN 4000 and RN 6000 cover the complete range of applications, from simple to extreme.
