Model 1372 High Accuracy Reducing Regulator


The model 1372 high accuracy regulator is similar in appearance and function to our standard 415 reducing regulator. However the 1372 controls outlet pressure about 10 times as precisely.
Outlet pressure is also about 10 times less affected by changes in inlet pressure. This is done by using a small pilot piston to control gas flow to a dome load area that operates a much larger sensing piston. See drawing.

One difference from the 415 regulator is that outlet pressure can not be adjusted to zero. A bias spring, necessary for operation, maintains a 200 PSI outlet pressure even when the adjusting knob is fully backed off.

The 1372 is a little longer than the 415 model. The 1372 regulator is available in outlet pressure ranges of 0 to 5000 PSI, and 0 to 6000 PSI. Seats are protected by a 30 micron internal filter. As with the 415 series regulator, the regulator seat, poppet assembly, and lifter are contained in an easily replaced valve cartridge. This low cost cartridge permits corp easy and fast is-held servicing.
The regulator is self venting. It can be provided unvented on special order.

An optional mounting bracket (part number 657) permits panel mounting in any orientation or extension from the panel surface.
