V43/V243 Series Pressure-Actuated Water-Regulating Valves Product/
Technical Bulletin
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.
This product is made of a copper alloy, which
contains lead. The product is therefore not to be used
on drinking water.
