Bachman Valves are sliding spool directional controls. With seals in housing
and multiple slots milled in the spools, they provide fast action for pressure
or vacuum in spring return or detent. In simplicity and versatility they
are often superior to poppet, ball, sleeve and other types. Satisfactory
for many gases and fluids to 125 psi, they give long life service in thousands
of applications, often in hostile environments formerly requiring stainless
steel.
Freezing is not a hazard for BACHMAN valves since acrylic will yield under
conditions which
destroy metal valves.
HOUSINGS are machined from transparent acrylic plastic, a material
which has long proved suitable for aircraft windows, outdoor signs and now,
for 15 years, in valve applications. BACHMAN valves withstand normal abuse
and neglect. They resist common solvents and chemicals and will maintain
their good looks through years of exposure to weather, sea water, steam
cleaning, etc. They are "user friendly" and available in hundreds
of models.
DELRINTMACETAL SPOOLS,
colored green for optimum visibility, provide light weight, long life, and
maximum efficiency.
ALUMINUM SPOOLS, coated with electroless nickel, are available upon
request.
THE CLEAR VIEW of valve function is often of great value in complex
circuits which are now made simple by our valves and integrated modules
FLOW CAPACITIES are standard for each port size: M valves have
a Cv factor of .25, R = .88, F =1.9, W = 1.9, H = 2.8. Certain 2 way models
are available in full Iron Pipe capacity, i.e., .437" dia.orifice for
1/4 NPT, .562" orifice for 3/8 NPT, etc.
NOMENCLATURE: Valves are generally signified by 3 letters and
3 numbers but with some exceptions. Normally, only the first letter is significant
and reads as follows: M = 1/8 NPT, R = 1/4 NPT, F = 3/8 NPT, W = 1/2 NPT,
H = 3/4 NPT. "K" indicates timers and logic elements with 1/8
NPT porting. In most valves, -22 indicates 2 way 2 port, .33, 3 way 3 port,
etc. Other symbols are non-significant.
