V43/V243 Series Pressure-Actuated Water-Regulating Valves
Description
The V43/V243 Pressure Actuated Water
Regulating Valves are designed to regulate
water flow through the condenser of large
refrigerated cooling systems. These
pilot-operated valves open on an increase in
refrigerant head pressure and provide
modulating operation.
The V43/V243 water regulating valves are
available for commercial and maritime
applications.
V43 valves are available for non-corrosive
low- and medium-pressure refrigerants such
as R-134A, R-404A, R-502, and R-507.
Specially designed V43 valves are also
available for ammonia service (R-717).
V243 valves are available for non-corrosive
high-pressure refrigerants such as R410A.
Commercial V43/V243 valves are
constructed with a cast iron body, brass
internal parts, and bronze seat material.
To resist the corrosive action of sea water, the
V43/V243 maritime and navy models are
constructed with a red brass body, bronze
and monel interior parts, and monel seat
material.
Refer to the V43/V243 Pressure Actuated
Water Regulating Valves Product/Technical
Bulletin (LIT-125683) for important product
information.
Features
• built-in pilot valve allows more precise
throttling
• easy adjustment allows service and
adjustment without breaking line
connections
• drain plug allows water to be drained
during shutdown to reduce the possibility
of freeze-up
• mesh monel screen protects pilot valve
from items such as dirt and scale and is
easily removed for cleaning and servicing
without breaking any line connections
