Kunkle Model 6252 Safety Relief Valves

Kunkle 6252 Safety Relief Valves feature versatile connections available in FNPT or flanged configurations to seamlessly integrate into various systems. With an extensive temperature range spanning from -20 to 406°F (-29 to 208°C) and a pressure range of 10 to 250 psig (0.7 to 17.2 barg), they are engineered to withstand a multitude of operational conditions. Constructed from heavy-duty cast iron and equipped with an enclosed spring and stainless steel trim, these valves exemplify durability and reliability.

Compliant with ASME I, VIII, XIII, and PED/PE(S)R standards for steam, air, and gas applications, the Kunkle 6252 valves are suitable for a diverse array of equipment, including steam boilers, generators, pressure reducing stations, air/gas compressors, and pressure vessels such as tanks, receivers, and intercoolers. Their robust design features a bolted bonnet for easy maintenance, lapped seats for optimal sealing, and dual control rings for precise adjustability and blowdown control. The heavy-duty lift lever assembly ensures smooth operation, while factory-sealed adjustments prevent tampering or disassembly. Each valve undergoes rigorous testing and inspection to ensure accurate pressure settings and minimal leakage, offering unparalleled peace of mind in critical industrial operations.
