Warren Controls Series 2900 control valves for process and utility applicationsDiana Aoun | December 10, 2021
Warren Controls recently announced its ILEA 2900E Series of electrically actuated, industrial globe-control valves. The 2900E Series features a robust cast-iron body with a range of trim options available, and comes with a modulating, linear, industrial electric valve actuator. The 2900E Series delivers reliability and long service life and is particularly suited to applications including food and beverage, packaged water heaters, wastewater, general services and pharmaceuticals.
The 2900E Series functions effectively for moderate pressure drops and temperatures ranging from -29 C to 204 °C (-20 °F to 400 °F). Valves are available in four models: two-way balanced, two-way unbalanced, three-way mixing, and three-way diverting. The equal percentage plugs in the two-way valves and the linear plugs in the three-way valves deliver superior modulating control for a wide variety of fluids.
Sizes range from DN65 to DN250 (2.5 to 10 in.) with ANSI Class II, III, and IV leakage and with a rangeability of 50:1. The durable cast-iron body comes in ANSI Class 125 pound and 250 pound with flange ends and bronze, 300 stainless-steel and alloy 6 trims.
The series model 2920 two-way single seat unbalanced valve is the most common model for sizes DN80 (3 in.) and under and features an ANSI Class IV leakage rating. The 2922 two-way double seat balanced valve provides an effective solution for sizes over DN80 (3 in.) and for higher pressures. Its double seat design allows for dirtier fluids and requires less force to operate than unbalanced valves so smaller actuators can be used. It is limited to ANSI Class III leakage rating. The 2923 two-way cylinder balanced valve is an effective solution for sizes over DN80 (3 in.) and for higher pressures. It requires less force to operate than unbalanced valves so smaller actuators can be used. Its single seat O-ring seal design facilitates ANSI Class IV leakage rating but is limited to cleaner fluids.
The 2930 three-way mixing valve features two inlets and one outlet and provides a simple solution for mixing or bypass applications with an ANSI Class IV leakage rating. Under normal operation, the inlet pressures are near equal, and control is possible across a large valve travel range for inlet pressures up 70 m (100 psi). Finally, the 2932 three-way diverting/mixing valve is designed as a diverting valve with one inlet and two outlets with ANSI Class II leakage rating.
