Compact and Economical PTFE Bellows Thermoplastic Solenoid
Valve...
For applications requiring a compact, cost effective and
high pressure rated valve
with extended cycle life.
Features:
- Compact Size: Only 4-9/16 in. high, these valves are ideal for
limited space installations.
- Economical: Low unit cost coupled with high pressure ratings
and considerable flow rate (Cv to 0.8) offer excellent opportunities for
systems requiring quick opening/quick closing solenoid valves.
- High Pressure: Particularly for applications where high back-pressures
(up to 70 PSI) are required e.g. controlling flow to spray nozzles, high
pressure chemical injections, etc. Inlet pressure to 140 PSI. Note that the 1/4" orifice design is NOT recommended for use with DC voltage.
- Unique Design: PTFE bellows barrier type dynamic seal prevents
leaking or fugitive emissions to the atmosphere.
- Versatility: Can be used with all type solutions. Includes acids,
caustics, solvents, chlorine solutions and ultra-pure liquids.
- Superior Performance: 2,000,000 cycle design.
- Energy Efficient: Molded 11 Watt NEMA 4 style coil with DIN
standard connector results in low energy consumption.
- Sizes: 1/4 in. and 1/2 in. pipe sizes with 3/16 in.(4.8mm) or 1/4 in.(6.4mm)
Orifice.
- Corrosion Resistant: Rugged thermoplastic construction is resistant
to both internal and atmospheric corrosion. No metal parts in wetted areas..
- Safety/Dependability: Patented Fail-Dry safety design feature
provides advance visual warning if seal malfunctions, while permitting
valves to continue operating until maintenance can be scheduled.
- Coil Connector Light: Can be ordered with this optional feature,
which lights up brightly to show when the solenoid is energized.
Note: Handling of Dry Chlorine & Use of Thermoplastic Valves: When ordering a valve for chlorine service, please specify "Chlorine-Vacuum" on the order. Plast-O-Matic Valves are not recommended for use with pressurized dry chlorine gas.

Notes:
- All Model Numbers must be completed with body material at the end as
follows: PVC with '-PV', Polypropylene with '-PP', and PVDF(Kynar) with
'-PF'. ex: EAST2V6W11-PV.
- The Model Numbers listed show Viton seals. For EPDM seals (optional)
change 'V' to 'EP'. ex: EAST2EP6W11.
- Model Numbers shown with 'W11' (water and dust tight NEMA 4 style coil).
- Valves are rated for full vacuum of 30 in. of mercury (Hg).
- For Voltages other than 120/60 consult factory.
- Note that the 1/4" orifice design is NOT recommended for use with DC voltage.

Series EASM & EASYM, 2-way molded solenoid valves that use a triple u-cup seal. These diaphragm valves are well suited to vacuum, pressure and drain applications. But for salt solutions, caustics, etc., use either of the next two valves. Range of sizes is 1/2", 3/4" & 1".
Series EASMD & EASYMD, 2-way molded solenoid valves that use a rolling diaphragm. These diaphragm valves are well suited to salt solutions, caustics, and other crystallizing liquids, but they are not designed for vacuum applications. Range of sizes is 1/2", 3/4" & 1".
Series EASMT & EASYMT 2-way Molded solenoid valves that use a dynamic PTFE bellows seal in lieu of u-cups or rolling diaphragms. The PTFE bellows line replaces all the different seal configurations, is suitable for all types of solutions, and all types of service. Range of sizes is 1/2", 3/4" & 1".
Series EASY-NO, Normally-open, direct acting valve in 1/4" & 1/2" sizes.
Series PS, Pilot-operated valve with outstanding pressure and flow performance. Uses PTFE bellows dynamic seal. Complete sizes 1/2" through 3", requires 5 psi differential for proper operation.
Series THP, Compact 3-way (aka diverter) valve.
Series WCM, Compact, direct-acting 2-way valve with stainless steel & silver wetted core. (this is the only Plast-O-Matic solenoid valve with a wetted metal core). Offers an outstanding combination of price and performance.
