ASV-1010K Anti-Siphon Back-Pressure Check Valve

Download Spec Sheet

Designed to reduce the possibility of unwanted siphoning due to changes in well and tubing conditions. The valve can also be easily set to provide a consistent back pressure for the chemical pump. This will help keep the output of the chemical pump consistent. The integral check valve provides an added safety factor, reducing the possibility of down hole pressures and fluids from backing into the chemical pump.
