Two Way Direct Acting Solenoid Valves

Two Way Direct Acting Solenoid Valve 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.

Solenoid valves are normally closed when de-energized. The patented 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.

Coil Selection
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.

Valve Selection Criteria - Solenoid valves selection is a combination of selecting the material of construction for the valve body, shaft seal type and elastomer. The sizing of the valve is dependent upon the flow rate required through the valve, the allowable pressure drop of the solution through the valve, the inlet pressure and back pressure of the solution. We will assist in the selection processEASMT & EASYMT - Teflon Bellows - For acids, caustics, chlorine and ultra-pure solutions.

Word and figurative mark of "People" brand was recognized by State Administration for Industry and Commerce as "China Famous Trademark" on January 5, which brought a big gift to the 10 th anniversary of the People Electrical Appliance Group.

i have a nema size 2 starter type s , not sure how to wire it?

the owner doesn't have the manual but he is telling me thats is supossed to work as a converter since i only have single phase to three phase, is it really supossed to work as a conveter _

There is no conversion that takes place in any size 0 through 7 type S starters. They may be attached to another conversion device but that would be defeating the purpose of the conversion device. It also may be used to connect a 3 phase generator to its load.
These switches are simply a coil energized armature that closes three contacts with incremental current ratings per size through a belcrank arrangement. Overloads may be integral to the device. Through high speed operation and lack of contact bounce, contact life is extended. The coil can be of a wide range of single phase AC voltages or even a DC voltage.
That's the most info I can offer based on what you supplied.
