SAI’s newest product line is Zwick, the world finest line of triple offset butterfly valves for steam isolation.
The number of unique technical attributes of the product, as the cone-in-cone seating design with the multiple laminations and the metal seat makes the series TRI-CON to an allrounder for many different industrial applications.
Zwick valves are used for industrial and exhaust gases, liquids, hot water or steam at lowest as well at high temperature zones up to 815°C. The TRI-CON is utilized extensively in the chemical, petro-chemical, oil & gas, offshore and district heating markets.
SAI’s standalone chemical feed system from Tacmina.
Available in 30, 50 and 120 liter sizes.
SAI can equip these systems with back pressure and anti-syphon valves per your specific application. We specialize in sodium hypochlorite feed for disinfection and hydrogen peroxide for odor control. These two liquids that cause most other systems to experience air binding, the Tacmina PTS with DCLPW anti gas head makes those problems a thing of the past.
SAI also offers the Van London pHoenix line of analytical sensors for pH, Conductivity, Ion Selective, Chlorine and Dissolved Oxygen measurement. These sensors are designed for the harsh environments found in industrial processes and are available in many form factors to facilitate easy, direct replacement of your existing sensors.
SAI is also the agent for most lines offered by Murphy and Dickey. As Murphy and Dickey’s agent, SAI will be serving Wisconsin and the Upper Peninsula of Michigan with a wide product portfolio. Murphy and Dickey has been an active sales representative organization since 1943 serving the upper mid-west.
We look forward to serving the upper mid-west region effectively, professionally and courteously for years to come.
