Solenoid operation provides instant on/off for precise control; Teflon bellows design eliminates fugitive emissions

50% Sodium Hydroxide, 93% Sulfuric Acid

In this typical industrial waste treatment system, the effluent from the manufacturing area is transferred to a treatment tank where either a caustic base to raise pH, or acid to lower pH, is injected to bring the pH into acceptable environmental levels.

Direct acting solenoid valves provide instant on/off, which is necessary for precise dosing. To eliminate corrosion problems and premature failures, the valves were selected with Grade 1, Type 1 PVC body and Viton seals for acid, EPDM seals for caustic. Valve design features no wetted metal parts, and has the added benefit of a Teflon bellows internal seal for long smooth cycle life and to prevent fugitive emissions.

The pressurized feed lines are teed off just prior to the solenoid valve to assure adequate chemical pressure at all times.

Direct Acting, Normally-Closed PTFE Bellows Seal Solenoid Valves Series EASMT/EASYMT
True Blue® Solenoid Valves Series EASMT & EASYMT for pressure, drain, and vacuum service; designed for all types of aggressive chemicals, salt solutions, acids, caustics, and ultrapure liquids such as deionized water.
