What is Packless diaphragm hand valve?
Evergreen’s Packless Diaphragm Valves are efficient valves with bodies that are forged brass having full size openings to ensure minimum pressure drop and maximum flow. They have integral mounting brackets that make installation easy.
What is the difference between cavitation and flashing?
Flashing is an in- to- out event while cavitation is an out- to- in event. Flashing occurs at low pressure and cavitation occurs when the low-pressure bubbles collapse at the high-pressure region within the pump casing producing a shock wave.
Which is handled by diaphragm valve?
Diaphragm valves are bi-directional, on-off throttle valves. They are used to control fluid flow by regulating the area with which media can enter and exit the valve, effectively changing its speed and velocity.
What is the advantage of straight through type diaphragm valve?
Specifically suited to handle erosive and abrasive applications, its unobstructed full bore provides excellent performance with low pressure drop. At valve fully open offers self cleaning design. It is the best choice for dirty, contaminated and powder media.
What is Packless valve?
Diaphragm packless line valves are small, compact valves which utilize metal diaphragms rather than stem packing to provide a positive seal.
What is valve cavitation?
Cavitation is the sudden vaporization and violent condensation of a liquid downstream of the valve due to localized low pressure zones. When flow passes through a throttled valve, a localized low pressure zone forms immediately downstream of the valve. The sound of cavitation in a pipeline is unmistakable.
Why do we use resistoflex lined check valves?
Resistoflex® ATL was designed specifically to address the challenges of handling severe service applications. It has been proven to reduce permeation rates by up to 60% and features a full vacuum rating up to 450°F (232°C). As such, ATL Lined Pipes and Fittings are an economical choice compared to Exotic Alloys or Glass Lining.
