Elite Flow Control’s Cast Steel Gate Valves are heavy-duty, full-port isolation valves engineered for durability and long service life across the most demanding industrial environments. Designed for efficient, bi-directional flow isolation with minimum pressure drop, these valves are the trusted choice for boiler plants, power generation facilities, petrochemical processing, and other rugged industrial applications.
Featuring an Outside Screw and Yoke (OS&Y) rising stem design, the valve provides clear and immediate open/close visual indication at all times – essential for safe operation in busy plant environments. Handwheel operated as standard, these gate valves deliver smooth, precise control with minimal operational effort.
The full-port design ensures an unobstructed flow path when open, eliminating unnecessary pressure loss across the valve and making them particularly suitable for applications where maintaining system pressure integrity is critical. A robust bolted bonnet construction with spiral wound gasket sealing ensures body/bonnet integrity throughout the valve’s service life, while the hardenable seat surface offers superior resistance to wear and erosion in both clean and mildly abrasive services.
Available in the Cast Steel PSB (Pressure Seal Bonnet) configuration for 900LB, 1500LB, and 2500LB pressure classes, 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 valves can be tailored to virtually any process or environmental requirement.
