Two-Way Direct Acting Solenoid Valves
For Corrosive and Ultra-Pure Liquids
Solenoid valves are designed using corrosion resistant thermoplastics and
premium elastomer seals to offer bubble tight shut-off service and million cycle
durability. Valves are normally closed when de-energized. The patented
Fail-Dry™ vented design with a secondary backup
diaphragm helps to avoid emergency shutdowns and gives a visual warning of potential
problems is standard on most models. Most valves are supplied with coils rated for
continuous service. Design - An electric solenoid coil is basically a simple electromechanical unit used to control the opening and closing of a valve. Energizing the coil creates a magnetic field which lifts the shaft and seat of the valve off its orifice. When de-energized a small spring pushes the shaft and seat down to close the valve. Response time is a split second.
- The coils used are available in 11, 20 and 58 watts with
- AC voltages of 24, 120, 240 and 480 at 60 Hertz (may be used with 15% less voltage @ 50 Hz.)
- DC voltages are 12 and 24.
- W11 and W20 - 11 and 20 watt coils are standard with weatherproof NEMA 4 polyester and nylon for corrosive environments. For indoor or outdoor service. Includes DIN connector with 1/2" conduit connection.
- E20 and E58 - Explosion proof enclosure and water tight connection - NEMA 7 - CL. 1- Group C & D
- DIN connector with indicator light is optional at modest cost
- 11 and 20 watt coils are rated for continuous service up to 95 F ambient temperature. 58 watt coils are rated for a 15 minute maximum on cycle.

EASMT & EASYMT - Teflon Bellows - For acids, caustics, chlorine and
ultra-pure solutions
EASMT and EASYMT is the most common applied of this group of
solenoid valves. Incorporating a Teflon bellow seal to prevent stem
leakage and Viton seat sealing allow this valve to be used for both acid
and caustic services. It offers the widest selection of sizes,
materials and coil configurations.
