Thermostatic Expansion Valves
410A
Sporlan offers thermostatic expansion valves in R-410A nominal
capacities between 1/3 and 60 tons (1.17 and 210 kW). The models
offered are externally equalized, have straight through or angle configuration,
and ODF connections.
The Sporlan refrigerant code for R-410A is the letter “Z”, which is
found in valve nomenclature.
The RZE models have the advantage of a balanced port construction,
which makes them ideally suited for systems with a wide range of
operating conditions.
The RCZE model is similar to the RZE but has an internal check
valve to allow refrigerant flow to bypass the expansion valve port in
the reverse flow direction in heat pump systems. The integral check
valve means fewer connections, easier installation, and increased
reliability.
The Sporlan TEVs designed for R-410A have replaceable thermostatic
elements designed for the higher pressures associated with R-410A.
Replaceable thermostatic elements are designated by:
KT – 45 – ZGA
Kit Element Size Charge
ZGA – Has similar performance to the VGA charge used in R-22 or
NGA charge used in R-407C systems. The constituents and heavy
thermal ballasts in the charge provide excellent anti-hunt characteristics
by dampening the valve in the opening direction. The maximum
operating pressure or MOP of this charge is not as defined as the
ZCP200 charge, an alternate charge for R-410A air conditioning and
heat pump applications.
ZCP200 – Has similar performance to the VCP100 charge used in
R-22 systems or the NCP100 charge used in R-407C systems. The
maximum operating pressure or MOP of this charge takes effect
around 66°F (19°C) evaporator temperature. The ZCP200 charge has a
mild thermal ballast that dampens the valve in the opening direction.
Contact the nearest Sporlan sales office if you have an application that
requires a valve or charge that is not listed.

Small brass body valve available with either angle
style or straight through connection pattern. RZE
valves are available both externally adjustable and
non-adjustable. The RZE has a balanced port construction,
which makes it ideal for applications with a
wide range of operating conditions. May be applied in
bi-directional applications.
In addition to the features described above for the
RZE valve, the RCZE has a built-in check valve to
allow bypass flow in the reverse direction. This feature
makes this valve type ideally suited for heat pump
applications. RCZE valves are available both externally
adjustable and non-adjustable.
