“A” — 1/4-in. Hex Allen Head
1/4-in. Hex Allen Head Durable 1/4-in. Allen head adjustment won't break like a screw slot.
Design allows for low-effort adjustment under full-rated pressures.
Exposed steel parts are
zinc- or cadmium-plated for corrosion resistance.
Positive stop prohibits A-, B- or C-type adjustments from taking the spring to a solid condition, thereby preserving circuit protection at the spring-range-specified maximum pressure.
 
“A-Alt” — 1/4-in. Hex Allen Head
(for valve models RVD50-20 and CB10-30 only)
1/4-in. Hex Allen Head Durable 1/4-in. Allen head adjustment won't break like
a screw slot.
Exposed steel parts are zinc-
or cadmium-plated for
corrosion resistance.
Fixed Height Adjuster and
integral spring-setting shoulder compress the internal spring to the desired pressure range. Height of the adjuster does not change. The adjuster screw will not back out of the valve when adjusted under pressure.
Positive stop prohibits
A-, B- or C-type adjustments
from taking the spring to a
solid condition, thereby
preserving circuit protection
at the spring-range-specified
maximum pressure.

 


“B” — 1-1/2-in. Diameter Aluminum Knob
1-1/2-in. Diameter Aluminum Knob Standard aluminum knobs won’t break like some plastic ones.
Set screw provides “A”
to “B” conversion using
kit no. 6260010.
Internal seals prevent
external leakage.
Generous raised hex
allows for easy installationusing common hand tools.

page 9.020.1.
 
“C” — 1/4-in. Hex with Cover Cap
1/4-in. Hex with Cover Cap
Protective cap no. 7006700
converts “A” to “C”.
Adjustment stems cannot
be backed out of the valve.
Springs are computer-
designed for stable, quiet
operation under a wide
range of load conditions.

 


“F” — Factory Preset, Non-Adjustable
Factory Preset Non-Adjustable The “F” plug is
field-removable only
if damaged.
