2-Way Normally Closed Valve
2-Way High Pressure Fixed Polarity Class I Div II Magnet Latching Valve - The N20 Latching Valves are CSA listed and certified for non-incendive Hazardous Location Class 1, Div 2, Groups A, B, C and D; T6 temperature rating. 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 the continuous application of power, is undesirable. Hot water, steam, gasoline, oils, some hydraulic fluids, and many other media require special seal materials.
Common Black wire set to Neutral (-) a. Pulse Yellow lead to Positive (+) to latch b. Pulse Blue lead to Positive (+) to un-latch

Ordering Information:
When ordering valves or repair packs add voltage and frequency to complete valve number. for examples: valve (N26JJ7XELM 12/DC) repair pack (KN26JJ3L DC)
Seal Material: Replace ∆ with desired code -Blank = Nitrile (Buna) S = Low Temp Buna. N = FKM* E = Neoprene A = EPDM

Cv Flow Formulae
PeterPaul has created this page for you so you can calculate the flow or Cv (flow coefficient) to make the relationship visible between the pressure drop (the difference in pressure between two points of a liquid/gas carrying network) and the flow rate.
The use of this flow coefficient (Cv) calculator offers a standard calculation to compare valve capacities and sizing for a wide range of applications. The type and sizing of a valve or regulator can have a large impact on the performance of the assembly for transferring gas or liquids in the system.
