Learn about Meyer’s Screw Pump qualities - valve life extender
Meyer Screw Pump Provides Extended Valve LifeA New Jersey based asphalt company approached Wm. W. Meyer & Sons seeking a solution to an issue they were having with a competitor’s airlock ability to hold a seal. The valve was lined with ceramic tiles and was supposed to have a one-year lifetime in that particular system. Unfortunately, the asphalt company realized the valves were only lasting 5-6 months at the most. The limited lifespan on the rotary valve ended up costing the asphalt company more than...
South Texas Landfill − Case Study
During 2011, four QED Precision Fine Tune Control Valves™ were installed in wells at a south Texas landfill. The following graphs show the composition of the landfill gas and flow data before and after the installation of the Control Valves in Wells 07, 54, 78, and 90. The closest neighboring well on the same trunk line, using a gate valve for flow control, was also chosen for an additional comparison. The screen shot (at right) shows the increase in value of the methane produced at Well 90 resulting from...

Learining how to Choose Materials for Gas Valves
The materials and the quality of gas valves are so important that their disqualification will lead to leakage in-or-outside the body of the valve. If the strength, rigidity and overall performance of the components of the valve body cannot meet the requirements or even break, it will result in the spillage of gas and explosion. Therefore, material and quality are the most critical part during the process of developing, designing, and studying gas valves.How to choose materials for Gas Valves: Mainly worked as...
Valves in Water System of Heating Air Condition
Common valves in water system of heating air condition include gate valve, globe valve and butterfly valve.Gate valeFor its moderate length, rotary adjusting rod and good regulating performance, gate valve is widely utilized in large caliber pipes.Globe valve Globe valve is suitable for small caliber pipes for its long length, rotary adjusting rod and good regulating performance (DN≤150mm).Butterfly valveButterfly valve has short length, handle regulating rod, bad regulating performance and high price. But it...
