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. NOW INCLUDES W24 Fully Rectified Coil with Z-Cool DIN. Uses 75% Less Energy Rectified R24 Coil Optional. Valves are spring return normally closed and direct acting with a heavy duty 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. Provides low friction sealing, non-sticking operation, and million cycle design. The bellows design also allows a stock valve to be used for vacuum or pressure. A poppet seat ensures bubble-tight shutoff. Available in 1/2", 3/4", and 1" sizes (EASMT) or 1/4" and 1/2" (EASYMT). The EASMT has a larger orifice, which permits higher flow with a slight reduction in pressure rating. The EASYMT has a slightly smaller orifice (.375") and offers higher pressures at the expense of flow. Even so, the 1/4" EASYMT has a Cv rating of 1.2, which is still outstanding. After 1,000,000 cycles, we recommend that the valve be disassembled and inspected. It is also recommended to replace the elastomer seals and bellows at this point. Contact your distributor for a seal kit. For heavy use applications, you may wish to order a spare seal kit with the valve. Seal replacement takes but a few minutes with common tools; no special training is required.
