1. For extended temperatures from -40F to 400F / -40C to 204C, consult TESCOM. 2. A secondary pressure drop due to the outlet cross-hole can significantly affect the rated flow capacity. Flow curves should be used for critical sizing applications. Teflon and Viton are registered trademarks of E.I. du Pont de Nemours and Company.
