If higher pressure drops are required, contact your <strong>Flowserve</strong> sales office.2. Additional material combinations are available. Contact your <strong>Flowserve</strong> sales office for respective pressure drops.Note: Values are for combinations shown only. Consult <strong>Flowserve</strong> for other alloys such as Hastelloy-C, Nickel 500, Duplex, etc. DO NOT EXCEED Pressure/Temperature limits per ASME B16.34 for body materials.Note: Allowable pressure drops for other alloys will be evaluated on application.7flowserve.com
