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.
