Swagelok SS-4CA-3 Poppet Check Valve, 316 Stainless Steel

Want backflow protection you can dial in exactly? The Swagelok SS-4CA-3 puts the cracking pressure in your hands. This 316 stainless poppet check valve lets you set forward-flow cracking anywhere from 3 to 50 psi with a simple turn of the adjusting screw, so you tune it to your line instead of settling for a fixed spring. The spring-loaded poppet reseats fast and clean to stop reverse flow before it reaches your pump, transmitter, or sample loop. A fluorocarbon FKM O-ring seals the seat for tight, low-leakage service. With a 0.37 Cv, it moves real flow without choking your system, and it handles working pressures to 3,000 psig at 100 degrees F. The 1/4 in. Swagelok tube-fitting ends connect leak-tight into the tube runs you already trust across analytical and process instrumentation. When your job needs directional control with a cracking point you actually get to choose, reach for the SS-4CA-3. Call Collins-Oliver for a quote.
