## Customer Reviews

### ⭐ 1.0 out of 5 stars







  
  
    Valve does not work correctly, gets stuck open
  

*by A***N on Reviewed in the United States on October 9, 2018*

At 300 psi, this valve began shuttering open and closed, eventually becoming completely stuck open. It is supposedly rated for 400 psi. This valve is a dud. My review was removed the first time, so I'm going to keep posting it until Kingston remedies the issue. Having a hot oil/steam valve get stuck open is a major safety hazard.
