Pratt Tilting Disc Check Valve Henry Pratt Co
The Pratt Tilting Disc Check Valve offers significant energy savings compared to other types of conventional check valves because of its larger flow area and low head loss characteristics. The valve achieves full opening when the disc tilts in the flow of the media.
Check Valves from Stayflow
OVERVIEW Check valves open with forward flow, and automatically return to close against reverse flow. The main function is to protect mechanical equipment, most notably pumps, where back flow can damage the internal components. Check valves may be grouped according to the way the closure member moves onto the seat.
Check Valves Air Check Valve
All Check Valves Certified to NSF/ANSI 61; Eighty years ago the specifier had only to pull out a standard swing check valve specification and add it to the system plans regardless of location or application. Today, however, engineers weigh the importance of slamming characteristics, headloss, cost of purchase and cost of maintenance when
Tilting Disc Check Valve With Counter Weight amp; Hydraulic
Tilting Disc Check Valve with counter weight amp; hydraulic dampers . Description . Tilting Type NonReturn check Valve is designed to installed at outlet of pump to prevent water and other medias flowing back or avoid destructive water hammer damaging valves and pipes etc. water supply system,when stop pumping or accidents caused by powder cut.
Crispin Tilting Disc Check Valves Valve Main Page
The hallmark of the Crispin Tilting Disc Check Valve is its superior design and function. Its concept provides the most efficient and solid approach to flow reversal. leaving 2/3 of the disc weight below. The resulting counter balance effect closes the valve quickly yet limits slamming. Pivot Pin Clearance Valves should be located a

Disadvantages of using conventional weight amp; Lever check valves in pumping applications. The traditional weight amp; lever Swing Check Valve has an 8090176; stroke from fully open to fully closed and requires an external Weight and Lever to speed up the closure of the Disc. Gravity is insufficient to close the valve fast enough, so a weight is required to prevent reverse velocities building

What is Piston Check Valve ? Piston Check valve Parts
Closure is accomplished by the weight of the check mechanism, by back pressure, by a spring, or by a combination of these means. The general types of check valves are swing, tiltingdisk, piston, butterfly, and stop. Piston Check Valve. A piston check valve is essentially a lift check valve. It has a dashpot consisting of a piston and cylinder
What is Tilting Disk Check Valve ? Tilting Disk Check
Closure is accomplished by the weight of the check mechanism, by back pressure, by a spring, or by a combination of these means. The general types of check valves are swing, tiltingdisk, piston, butterfly, and stop. Tilting Disk Check Valve. The tilting disk check valve is similar to the swing check valve. Like the swing check, the tilting

Check Valves, Ball check Valves Flomatic Valves
Check Valve Manufacturer. Check valves are mechanical devices that permit liquids and gases to flow in only one direction, preventing flow from reversing. They are classified as oneway directional valves meaning they have two openings in the body, one for fluid to enter and the other for fluid to leave.
Check valve
A swing check valve or tilting disc check valve is a check valve in which the disc, the movable part to block the flow, swings on a hinge or trunnion, either onto the seat to block reverse flow or off the seat to allow forward flow.The seat opening crosssection may be perpendicular to the centerline between the two ports or at an angle. Although swing check valves can come in various sizes
