Hoke 6253G8Y 6200 Series Poppet Check Valve, 1/2 in. Gyrolok, 316 Stainless Steel

Want one-way flow protection that passes big volume without chatter? The Hoke 6253G8Y poppet check valve gives you both. Its spring-loaded poppet opens smoothly on forward flow and snaps shut against reverse flow, guarding your pumps, gauges, and instruments from costly backflow. The poppet design moves large flows with minimal fluctuation, so you protect the line without choking it. A 316 stainless steel body fights corrosion in refinery, petrochemical, and power service, and the 0.422 in. orifice keeps pressure drop low. The 1/2 in. Gyrolok tube ends lock onto your tubing with a two-ferrule grip that resists blowout and vibration. You can order the valve with the cracking pressure your system needs, from a light 1/3 psig up to 25 psig, so the check opens right where your process wants it. Rated to a full 6,000 psig at 70 degrees F, this valve holds firm in high-pressure lines. When you need dependable, high-flow backflow protection, install the 6253G8Y.
