Check valves are automatic shut-off valves that are commonly used for preventing backflow or drainage in a piping system. Often applied on the discharge side of pumps, check valves prevent the system from draining if the pump stops and protects against backflow, which could harm the pump and/or other equipment.
Features
- Cost Efficient Design: Low weight and short laying length produce savings in initial cost, space requirements, and installation when compared to full body, swing type check valves
- Minimal Head Loss: Contour of body provides a short and straight flow path that generates very little turbulence - Additionally, the spring loaded discs are designed with very low cracking pressure which reduces the amount of energy required to open the valve
- Quick Closure to Reduce Water Hammer: Silent shut-off is achieved via the fully automatic, spring assisted disc that closed near zero flow velocity - The lightweight, split disc design creates a positive shutoff prior to flow reversal and helps to keep slamming and surges to a minimum
- Designed for Long Service Life: The spring and discs are designed to allow the discs to lift linearly before pivoting to avoid the disc heal from scrubbing the sealing surface - also, discs are equipped with cast-in shock bumpers that help to reduce wear and tear on internal components
- Fugitive Emission Design: Titan's innovative retainer design eliminates potential leak path to the environment so there are no body emissions
- Resilient Seats: Viton/Nitrile Rubber Ensures a bubble tight seal
- Versatile Design: Sizes 2 - 6 in. utilize a unique scallop design that permits dual pressure service (ASME Class 150 and 300)
