Butterfly valves and gate valves are commonly used for pipeline isolation, while check valves prevent reverse flow. Y strainers can help protect pumps and downstream equipment from debris. Final selection depends on the process stage, medium, pressure and pipeline size.
Consider the flow rate, operating pressure, pump shutdown characteristics, installation space and potential water hammer. Swing, tilting disc, dual plate and silent check valves have different closing characteristics, so the valve should be selected according to the hydraulic conditions.
Resilient seated wafer or lug butterfly valves are commonly used in chilled-water systems. Selection should consider pressure, temperature, water or glycol concentration, insulation clearance, stem position and manual or actuated operation.
Please provide the application, medium, concentration where applicable, DN/NPS, PN/Class, temperature, material, connection, operation method and quantity. Required standards, certifications, destination country and available drawings or datasheets are also helpful.
