THERMOSTATIC EXPANSION VALVES
Refrigerant 410A
Sporlan offers thermostatic expansion valves in R-410A nominal
capacities between 0.88 and 28 kW. The models offered are externally
equalized, have straight through or angle configuration, and SAE or
ODF connections.
The BIZE models have a conventional port construction. BBIZE
models have the advantage of a balanced port construction, which makes
them ideally suited for systems with a wide range of operating conditions.

The CBIZE and CBBIZE models are similar to the BIZE and BBIZE,
but have 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 with a locknut ring stronger than normally used with common
refrigerants such as R-22 or R-134a.

BIZE and BBIZE valves are available both externally
adjustable and non-adjustable.
The difference between the BIZE and the BBIZE valves is
that the BBIZE valve has a balanced port construction,
which makes it ideal for applications with a wide range of
operating conditions.
In addition to the features described above for the BIZE
and BBIZE valves, the CBIZE and CBBIZE have built-in
check valve to allow bypass flow in the reverse direction.
This feature makes this valve type ideally suited for heat
pump applications.
CBIZE and CBBIZE valves are available both externally
adjustable and non-adjustable.
