DESCRIPTION
NO. 87, 67, and 7 AUTOMATIC AIR VENTS - are designed to vent
the accumulation of troublesome air wherever it can be trapped.
These non-ferrous automatic air vents are
4-3/4"x2-1/4", 3-3/16"x1-1/2", and 4-1/6"x2-3/16"(height and width),
respectively, and are rated for a maximum operating temperature o
f
240°F at pressures of 150, 35, and 75 PSI, respectively. The No. 87
has a combination of 1/2" FPT / 3/4"MPT connection, whereas No's.
67 and 7 have 1/8" MPT and 1/8" FPT connections, respectively.
No. 26 VACUUM BREAKER - Designed to protect closed vessels
and piping systems against collapse when the induced vacuum
exceeds design conditions. When used on steam heating piping
systems, the No. 26 Vacuum Breaker controls induced vacuum
permitting normal return of condensate to the boiler. Adjustable
range 1/4" to 20" (mercury) vacuum - 150 PSIG maximum working
pressure - 240 °F maximum operating temperature (Factory set at 4"
mercury).
No. 17 SR. AUTOMATIC AIR VALVE - No. 17 Sr. Valve is a deluxe,
hygroscopic air valve with manual shut-off. 1/8" MNPT connection.
30 PSIG Working Pressure
225 °F Maximum Operating Temperature
No. 4V "COIN-OPERATED" AIR VENT - This vent is specially
designed for the new types of radiators. A particular feature is that it
projects only slightly, being almost flush with the radiator.
150 PSIG Working Pressure
250 °F Maximum Operating Temperature
NO. 107A HIGH CAPACITY AIR VENT - A rugged High Capacity Ai
r
Vent designed to purge free air from liquid systems at operating
pressures up to 150 psig. The Model 107A Air Vent has a cast iron
body and bonnet, with stainless steel, brass, and EPDM internal
components and is suitable for a maximum operating temperature o
f
250°F. The Model 107A Air Vent has a 3/4" FNPT inlet and 3/8"
FNPT outlet.
RV-125A READOUT VALVE AND RP-250B READOUT PROBE -
The RV-125A is designed for use wherever pressure tappings are
required to monitor flow or pressures. This Readout Valve is fitted with
an EPT insert which incorporates a unique check valve feature
designed to check flow when the Readout Valve is not being used to
monitor flow. Use companion RP-250B Readout Probes with the RV-
125A Readout Valve. 300 PSIG working pressure - 250°F maximum
operating temperature.
