Compact, Normally-Closed PTFE Bellows Seal Solenoid Valves
Series EAST
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: Tested to 2,000,000 cycles, with city water in laboratory conditions.
- 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.
Design and Operation:
Valves are spring return normally closed and direct acting with a simple push-pull plunger design. There is no minimum pressure required for operation. The PTFE bellows shaft seal eliminates the need for an elastomer seal which can weaken as a result of chemical attack. The PTFE bellows assures non sticking operation and exceptionally long cycle life. The bellows design also allows a stock valve to be used for vacuum or pressure. The poppet seat ensures bubble tight shutoff.
Pressure Rating Considerations:
Inlet Pressure: Inlet pressure rating in the tables below are at full rated line voltage for alternating current (A.C.). If line voltage is 10% lower, inlet pressure rating will be about 30% lower. If rated pressures are exceeded the valve will not open and the coil will burn out.
Outlet (Back) Pressure: An important consideration in solenoid valve selection is back pressure rating (max. outlet) shown in the spec table. Back pressure is caused by the resistance to flow in the piping downstream of the valve and is the most common source of solenoid valve problems during start up. Nozzles, goosenecks, fittings, tubing, or reduced outlet piping all create restrictions that raise the back pressure so these sources must be considered in planning a piping system. Although the EAST valve is capable of handling high back pressures, values shown in the spec table should not be exceeded.
Notes:
Valves are rated for full vacuum of 30 in. of mercury.
For Voltages other than 120/60 consult factory.
Note that the 1/4" orifice design is NOT recommended for use with DC voltage.
