Product Overview
regulator combined with an electric shut-off feature, or (S)PORT, and a unique combination of electric shut and
bypass feature, the (S)PORT-B. The (S)PORT version is typically applied on a refrigeration circuit utilizing hot gas
for defrosting purposes, while the (S)PORT-B offers the same capability in addition to a wide opening, or bypass
feature, for quick pull down during start up or after a circuit's hot gas defrost period has been terminated. A water
resistant class F coil and open frame coil housing is standard on the (S)PORT regulator line. Solenoid coils with
DIN connectors can also be supplied.
S8 Solenoid Valves
S8 solenoid valves are flexible by design, suitable for discharge gas applications or as
a liquid feed valve. S8 solenoid valves can also be applied on a low side (suction line)
application. If (S)PORT pressure regulators are being considered, however, on a super-
market rack system for example, the Refrigerating Specialties “SC” solenoid valve would
be a better option (see description below) as suction shut-off devices. Overall, the design
of the S8 solenoid valve with regards to its major components, complements that of the
A8 regulator. That is, the valve bodies, cartridge assemblies, solenoid operators, and
solenoid coils are identical to those used on the A8 regulator line. The same class “H”
coil and general purpose coil housing which are standard throughout the A8 regulator line are supplied with the
S8 solenoid. Along with the A8 line of regulators, solenoid coils with DIN connectors are also available.
SC Solenoid Valves
The "SC" line of solenoid valves were designed to complement (S)PORT pressure
regulators in both appearance and construction. Components such as valve bodies,
cartridges, solenoid operators, and solenoid coils are interchangeable between the
SC solenoid and (S)PORT regulator lines of valves. Like the (S)PORT regulator, the
SC solenoid is available with either ductile iron materials (both body and cartridge) or
corrosion resistant aluminum bronze materials. With the (S)PORT regulator and SC
solenoid combination, any suction line control requirement can be satisfied while main-
taining reliable performance and common appearance. The SC line of solenoids utilizes
the same water resistant class F coil and open frame coil housing which is standard with
the (S)PORT line of regulators.
A9 Pressure Regulators
A9 outlet pressure regulators utilize a compact design unique to the Refrigerating
Specialties line of regulators, and are applied most typically as hot gas bypass or
receiver pressure control valves. Four port sizes ranging from 3/8" (9mm) through 1-1/8"
(28mm) are available. Utilizing a pilot operated design for stable control of set point, the
A9E is typically used as a hot gas bypass regulator. The A9E regulator, when used in a
hot gas bypass application, is externally equalized to suction pressure, or the pressure
being controlled. Through years of reliable performance, it has become a standard on a
variety of OEM equipment where precise suction pressure control is required for stable
system operation. The A9, an internally equalized regulator which senses and controls
immediate downstream pressure, is typically applied as a receiver pressure control valve
for those systems using regulators for condenser pressure control on air cooled condensers.
CK4A In Line Check Valves
CK4A in line check valves are versatile spring closing disc check valves, used for most
hot gas and liquid line applications. The CK4 series of check valves are a flanged family
of check valves, utilizing a gasketed refrigeration style tongue-and-groove ODS flange
for commercial applications. Eight port sizes are available ranging from 1/2" (13mm)
through 4" (100mm). Up through and including the 2" port size valve, three different
ODS connection sizes are available for each port size valve to accommodate a reduced
capacity valve in larger lines. All valves are made to tight seat leakage specifications,
utilizing a lapped metal-to-metal seat design. The pressure drop required to open the
valve fully is about .75 psi. Because of it's spring closing design, CK4 check valves can
be intalled in both vertical and horizontal pipe lines.
