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.
Note: Viton offers a broad range of chemical resistance and excellent heat resistance. Good mechanical properties and compression set resistance. Often used where nothing else will work. Fair low temperature resistance and limited hot-water reistance and shrinkage.
Features
- Lug Style Design: Low weight and short laying length produce savings in initial cost, space requirements, and installation - Threaded on both sides of body and can be used as a block valve for the pipeline
- 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 ensures a bubble tight seal - meets or exceeds API 598 test requirements
