3-way, high pressure solenoid valves for aggressive chemicals

3-way High Pressure Solenoid Valves

True Blue® diverter or sampling Solenoid Valves Series THP.

Series THP is a 3-way solenoid valve for all types of nasty chemicals, as well as ultra-pure liquids.

Series THP 3-way design:

Diverter or "sampling" valves with no metal parts in wetted area. Design features a non-sticking shaft with an upper and lower diaphragm separating the liquid from opposing springs, plus secondary seals with Fail Dry safety vents. Suitable for virtually all solutions. Series THP is not specifically designed for vacuum service; consult factory if needed.

Ultra-smooth, balanced shaft permits use with high backpressures.
Bubble-tight sealing.
No metal parts in wetted areas.
NEMA 4X 20 W coil standard; NEMA 7 & 9 optional.
1/4" & 1/2" NPT sizes, with variety of orifice sizes.
Can be converted to 2-way if needed.
Available in Geon PVC. Elastomer seals in Viton or EPDM. Alternate materials available w/quantity orders.

Mode of Operation:

Direct acting; flow is normally through an outlet port, at 90 degrees from the inlet port, on the same plane. When the valve is energized, flow is switched to an outlet port inline with the inlet port, also on the same plane.

Service:

Pressure or drain. (for vacuum applications, please call our Tech Group at 973-256-3000).

Application:

Series THP diverts flow of highly corrosive and ultra-pure liquids. Suitable for virtually all types of corrosive and ultrapure liquids. They do not require pressure to aid in opening the valve.

THP is ideal for sprayhead or filter applications where high backpressures exist.

Design:

These True Blue solenoid valves are direct acting. They have an upper and lower diaphragm separating the liquid from opposing springs. They are constructed of Geon PVC with Viton or EPDM diaphragms. External fasteners are stainless steel (no metals in wetted area).

Available in 1/4" and 1/2", the THP has a Cv rating at .31 with a 1/8" orifice, .52 with a 3/16 orifice, and .61 with a 1/4" orifice.

Valve performs to 1,000,000 cycles with EPDM diaphragms (Viton diaphragms perform to 100,000 on Series THP). After 1,000,000 cycles (100,000 for Viton), we recommend that the valve be disassembled and inspected. It is also recommended to replace the elastomer seals and u-cups 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.

Pressure considerations:

Inlet and backpressure to 100 psi (4,8 bar) at room temperature (75 F) with smallest (1/8") orifice. Drops to 70 psi with 3/16" orifice, and 40 with 1/4" orifice.

If one of the outlets is plugged to create either a normally-closed or normally-open 2-way valve, the maximum pressure ratings are 40 psi inlet and backpressure.

Coil Info:

A 20 watt NEMA 4X continuous duty coil is standard. When the coil is energized, the valve closes and will remain closed until the coil is de-energized. Coils are available in general purpose or explosion-proof, water tight construction. AC voltages are 24, 120, 240 and 480. DC available; please call our Tech Group at 973-256-3000. Other coils available.

Specifications and Model numbers for the classic True Blue three-way solenoid valve

**Model numbers shown with "W20" NEMA 4X coils. If explosion-proof coil is required, replace "W20" with "E20" in the part number. If general purpose coils are needed, replace with "G20". With all coils, please specify voltage.

NOTES: Maximum inlet pressure ratings are at full line voltages. Other materials are available; consult factory. The maximum pressure differential is the same as the maximum inlet pressure. 1/8" and 3/8" sizes are available in quantity purchases, or we suggest you simply use an appropriate bushing. It is possible to create either a normally-open or normally-closed 2-way valve by simply plugging the appropriate outlet. Pressure ratings in the table are at 75 degrees F (24 C). The THP is not yet represented on our CADlink page. If you need a drawing for your project, we recommend that you right-click the image above, and "save as."

Electrically-actuated 3-way Ball Valves, which provide excellent flow and pressure capability in a diverter valve...as long as the less-rapid shutoff is acceptable.

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 EAST, Compact valve with outstanding performance. Uses PTFE bellows dynamic seal, 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 EASY-NO, Normally-open solenoid 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.

DID YOU KNOW that every single product manufactured by Plast-O-Matic Valves, Inc. must pass individual inspection prior to shipment? That each valve is tested, under pressure, for proper performance? Even the smallest, lowest-priced products we make (miniature gauge guards) are hand tested, one-at-a-time. If our inspectors don't like it, it doesn't get shipped to you.
