Series 20 Model MLV23 (REVERSE POLARITY) - Piped Exhaust

3-Way Reverse Polarity Magnet Latching Valve — Piped Exhaust this type of valve is often used in remote areas where continuous power may not be available or with battery-powered portable equipment where power capacity is limited, as it only uses power during latching and un-latching. It is also valuable in equipment where coil heating, due to continuous application of power, is undesirable. Air and other fluids are compatible with standard Buna seals. Hot water, steam, gasoline, oils, some hydraulic fluids, and many other media require special seal materials.

Ordering Information:

Seal Material: Replace ∆ with desired code -Blank = Nitrile (Buna) S = Low Temp Buna. N = FKM* E = Neoprene A = EPDM

When ordering valves or repair packs add voltage and frequency to complete valve number. for examples: valve (23JJ7DELM 12/DC) repair pack (K23JJDJ DC)

When ordering operators add the letter “O” to the front of the valve number, replace body port number with the letter “D”: example: operator (O23JJDDELM 12/DC)

Operating Conditions:

Media:

Air and other fluids compatible with standard Buna seals. Hot water, steam, gasoline, oils, some hydraulic fluids, and many other media require special seal materials. (Series 20 pressure ratings may change due to the viscosity of the liquid.)*
