SCX
• Application: Chillers, cold chain boxes, heat pump air
conditioner, air conditioning, etc.
• Suitable for refrigeration systems with hot gas defrosting.
• The same products can be used for R22 and R407C.
• With superheat external adjust device.
QCX, RCX
• Application: Commercial refrigerator, freezer,
air conditioner, cold chain box, etc.
• Suitable for refrigeration systems with hot gas defrosting.
• Type QCX … Internal equalizer type
Type RCX … External equalizer type
• The same products can be used for R22 and R407C.
• With superheat external adjust device
DPR
• Type SPR … Di rec t operated, 2-way valves, designed for
maintaining suitable compressor suction pressure in
refrigeration or air conditioning units.
Fitted in suction line after the evaporator to prevent
compressor overload.
• Type DPR … Fitted in by-pass line between compressor discharge
and suction line in refrigeration or air conditioning
units. (Quantity order only.)
Senses excessive compressor discharge pressure and
releases it through the bypass line to the low pressure
side to protect the compressor from overloading.
Reduces frequency of cut-in and cut-out of high
pressure switch to keep the compressor operating.
A typical advantage is in the heating cycle of heat
pump systems during spring or autumn, or at the
time when filter is clogged with foreign materials.
EPR
• Evaporating pressure regulating valves
• Direct operated, 2-way valves designed for maintaining
suitable evaporating pressure in refrigeration. Fitted at
the evaporator outlet to keep suitable set evaporating
pressure.
HEV
● Pressure Reducing Valve
Type CRV
• This water valve can be connected directly to a
water conduit.
● Relief Valve
Type WSV and VSV
• This valve being provided with a diaphragm is highly
reliable and the most suitable for the maintenance of
a hot water supply unit. (WSV type)
• This valve is provided with a negative pressure
operating device. If the hot water supply unit or
piping becomes a negative pressure internally, this
device introduces the atmospheric pressure to
prevent the damage of the unit and a reverse flow.
(VSV type)
RPV
• New solenoid valves for refrigerant “High-pressure
R410A standard”
• Various product line up (Body: 21 types, Coil: DIN plug
type, Lead wire type)
• Low power consumption (6W at 50Hz / 4.5W at 60Hz)
REV, UEV
• Type REV: Pilot operated, 2-way, Normally closed valve.
Type UEV: Pilot operated, 2-way, Normally opened valve.
• For non-corrosive refrigerant (liquid or gas) in refrigeration,
cooling, air conditioning systems.
• “Double plunger” construction provides reliable On/Off
action.
• Compact molded coil commonly fits all valve sizes.
• Operates in any position … can be conveniently located in
horizontal or vertical line with coil on top.
• Manual Opening Stem … On Flange connection models,
supplied as standard. On Flare or Solder connection
models, supplied upon request.
WEV
• Pilot operated, 2-way, normally closed valve.
• For water in refrigeration, cooling, air conditioning
systems, and general industrial plant.
• Valves for non-corrosive brine are available. To order,
specify catalog No. with “B”
Example: WEV–1504GLW for water
WEV–1504GLB for glycol, warm water
• Compact molded coil commonly fits all valve sizes.
• Operates in any position … can be conveniently located
in horizontal or vertical line with coil on top.
