RANCO
4-Way Reversing Valve is designed for residential and commercial
heat pumps (unitary and split systems), including air and water
heat sources.
APPLICATIONS
The
RANCO 4-Way Reversing Valve, when installed in a heat pump system,
reverses the direction of refrigerant flow through the heat exchanger
coils to provide heating or cooling from the system and to provide
for defrosting of the outdoor coil in air source units. It is designed
for residential and commercial heat pumps (unitary and split systems),
including air and water heat sources.
|
| SPECIAL
FEATURES |
|
- Designed for minimal pressure drop to allow higher system efficiencies.
- 4-way pilot valve uses high and low side refrigerant pressure
to push and pull the main valve slide for positive reversals
at low pressure differentials.
- Hermetic construction using high quality materials (brass,
copper, stainless steel) to eliminate external leakage
for longer system life
- Teflon® lubricated sliding surfaces provide reduced internal
friction and high contaminant resistance to provide longer valve
durability and reliability (V4–V12).
- Low solenoid power consumption provides a Class B UL thermal
rating for AC coils.
|
- Solenoid coils have 1/4 male quick connects and are color coded
by voltage.
- Solenoid coils can be removed within the length of the
valve body and can be shipped attached to the valve in a choice of
4 positions.
- Available W29 wiring harnesses are shipped separately.
- Wiring harnesses can be specified at various lengths, terminations,
and identification.

Minimum
capacities shown are recommendations based on standard
ARI conditions (45° F Evap. 130° F Cond., 10°F
SH, 10° F SC, 64.8 Btu/lb. H) and reciprocating compressors.
System manufacturers are encouraged to conduct their own
application testing to assure positive valve reversals
under all anticipated operating conditions.
Nominal
Capacity shown at 2 psig suction pressure drop. Maximum
capacity not shown; Suction pressure drop vs. valve type
used must be rationalized.
|
Valves for systems using alternate compressor styles and/or
high efficiency, large volume coils should be evaluated for
proper sizing to ensure minimum valve pressure drop and capacity
for reliable reversals. Male O.D. tube sizes are also available. |
