Check Valve Overview
Check Valves are automatic shut-off valves that are commonly used for preventing backflow or drainage in a pipe 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.
Swing Check Valve has a flat disc that pivots or swings about a hinge pin. They are low cost, and have low head loss characteristics when fully open. But because of the long stroke and inertia of the disc, the traditional swing check valve may slam in vertical pipe installations. These valves are therefore sometimes outfitted with a lever and weight accessoryy. They can handle liquids with solids such as wastewater.
Features:
- Economical 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: Head loss is minimized by providing a short, straight and virtually unobstructed flow path
- Quick Closure to Reduce Water Hammer: Shut-off is achieve via the fully automatic, spring assisted disc that closes near zero flow velocity - the lightweight, sing disc design creates a positive shutoff prior to flow reversal which helps keep surges to a minimum
- Resilient Soft Seats: coupled with precision machined sealing surfaces help to ensure a bubble tight seal that meets or exceeds API 598 test requirements
