Poppet check valve CSFA series

hydraulicpneumaticin-line

This miniature, zero-leak check valve is only 0.187 inches in diameter and 0.63 inches in length. This check valve utilizes an elastomeric seat material to provide zero leakage in the checked direction. It is ideal for pneumatic and hydraulic applications with flow rates up to 0.8 GPM. An integral safety screen is available for increased protection against contamination. - Poppet-Style Check Valves - Diameter: 0.187 inches - Lohm Rate: 400 Lohms max - Operating Pressures: Up to 3000 psi - Leakage: 0 bubbles / minute General Performance - Cracking Pressure: 5 ± 3 psid - Lohm Rate: 400 Lohms Max Restriction When Fully Open - Leakage in Checked Direction: Zero Leakage From 5-3000 psid - Nominal System Pressure: Up to 3000 psi - Nominal Weight: Unscreened Configurations: 2.3 grams, Screened Configurations: 2.7 grams - Available Screen Hole Size: 0.015 inches Nominal - Test Fluid: Air at 70°F Materials - Body: 304 CRES, AMS 5639 - Cage: 304 CRES, AMS 5639 - Poppet: 15-5PH CRES, AMS 5659 - Seat: 15-5PH CRES, AMS 5659 - Springs: 17-7PH CRES, AMS 5678 - Pin: 17-4PH CRES, AMS 5643 - Elastomeric Seat Option 1: Fluorocarbon, AMS-R-83485 or AMS-R-83248 - Elastomeric Seat Option 2: EPDM, MIL-R-83285 - Screen (Reverse Screened Version Only): 303 CRES, AMS 5640 - Screen (Forward Screened Version Only): 304L CRES, AMS 5647 - Braze (Forward Screened Version Only): AMS 4774 - Post (Forward Screened Version Only): 303 CRES, AMS 5640 Finish: All CRES parts passivated.
