Elite Flow Control’s API 602 Forged Steel Globe Valves are precision-engineered, high-integrity flow control valves designed for reliable throttling, regulation, and on/off isolation service in high-pressure and high-temperature applications. With bodies and bonnets manufactured from high-quality forged steel, these valves deliver exceptional mechanical strength, superior pressure containment, and extended service life – even under the most demanding process conditions.
Unlike gate valves, the globe valve’s design allows for precise flow regulation, making it the preferred choice wherever accurate control of flow rate, pressure drop, or fluid velocity is required. Available with a choice of conical seat or flat seat disc configurations, these valves can be matched to the specific sealing and throttling requirements of each application.
Featuring an OS&Y (Outside Screw and Yoke) rising stem, open/close position is immediately visible at all times – a critical safety and operational advantage in busy plant environments. The two-piece self-aligning gland ensures consistent packing stress and effective stem sealing throughout the valve’s service life, while the spiral wound bonnet gasket guarantees reliable body/bonnet integrity under all operating conditions.
Available in SW(NPT) bolted bonnet, flanged bolted bonnet, and SW(NPT) welded bonnet configurations across pressure classes from 150LB to 1500LB, and constructed from a comprehensive range of ASTM-standard materials including carbon steel, low-temperature carbon steel, stainless steel, duplex stainless steel, and alloy steel – these globe valves can be specified for virtually any process fluid or service environment.
Widely used across oil & gas, power generation, petrochemical, chemical processing, and allied industries for steam, water, oil, gas, and corrosive fluid services.
