Review on 💧 Efficient Water Flow Control with HFS Electric Solenoid Valve by Shahed Cleveland

The valve looks nice and the on/off celenoids work well. Unfortunately, once installed, it lets a small amount of gas through in the closed position. The ultimate purpose of the valve is to turn gas flow on and off. If it can't be done perfectly, it's useless. Update: HFS has been of great help by working with me to determine why the valve is not fully closing. We have concluded that the valve works well but is not suitable for domestic natural gas use. The valve is of good quality and is likely to be suitable for a variety of uses. However, the only exception is in very low pressure applications such as B. domestic natural gas. The internal pressure of natural gas is less than 1/2 psi. The pressure is too low to completely close the rubber membrane.
