A Southbend Range 4220-1 Bonnet secures the valve assembly for reliable flow control and steady system performance.
The bonnet secures and seals the valve assembly so liquid can be controlled properly during draw-off operation. Its 1-1/2-inch configuration and bonnet construction are important because they maintain proper fit, support dependable sealing under use and withstand the demands of commercial equipment service.
The bonnet might need replacement if the valve shows leakage, poor shutoff, inconsistent flow control or difficulty opening and closing during operation. Physical signs can include visible wear, corrosion, cracking or damaged sealing surfaces and environmental signs may include buildup from heat, moisture or repeated exposure to demanding kitchen conditions.
