Preventing the High Cost of Crop Failure with Hydraulic Pressure Sensors

Failure is a costly proposition in any industry – and agriculture is certainly no exception. The New York Times reported earlier this year that the U.S. Department of Agriculture estimated total losses of $15.8 billion from crops harvested in 2012, thanks to a nasty drought. That’s up from $9.4 billion in 2011.

Farmers can’t control the weather, of course, but they’ve come to trust companies to design machinery using components such as hydraulic pressure sensors. These small pieces of hardware precisely meter the performance of automated equipment. This precision gives farmers the ability to improve the outcome of those things that can be controlled.

Why use DFT Valves

Why Use DFT’s ALC and WLC Wafer Check Valves
Water hammer and reverse flow can be ongoing issues for commercial buildings and industrial piping. Unreliable double door or butterfly check valve are most often utilized and the results are these damaging issues. Failure of the door spring or hinge pin; leakage from misaligned doors and seats; reverse flow; and even internal parts flowing down stream are the result.  Damage to pumps and compressors is a costly proposition. Water hammer is a direct consequence of a slamming swing check valve. Noise above acceptable levels and vibration and swaying in the pipeline can cause catastrophic failures.
DFT’s Answer to Faulty Valve Problems
DFT has developed a valve to replace and solve these problems. DFT’s ALC Wafer Check Valve is an in-line, spring assisted, center guided “wafer” check valve which was specifically designed and manufactured to control “water hammer” and “reverse” flow.
Another DFT valve that minimizes the issues of water hammer and reverse flow is the DFT Model WLC Wafer style Silent Check Valve. The WLC is a lightweight, spring-assisted, in-line check valve that provides reliable, low maintenance service for a wide range of fluids and pressure/temperature combination. It is dual-guided and manufactured in carbon steel, stainless steel, and other exotic alloy materials.

ALC & WLC Valve Overview:

  • Easy to maintain
  • Lightweight design
  • Works for liquids, gases, and steam
  • The ALC Valve meets API 595 Face-to-Face dimensions
  • Fits between mating flanges
  • Easy installation: Tapped holes in body for lifting lugs
  • Low maintenance
