Testimonial

The Koike Back Pressure Valves that we have been using at Sandfire Scientific Ltd for the last 20 plus years. We have never had a failure of one of these valves in all of that time and we have about 50 of the valves on oxygen lines at 120 psig and 50 of them on Propane lines at 12 psig.  We expected to have some failures on the Oxygen lines as we knew that we were pushing the limit of the valves at 120 psig of pressure and have been very impressed with their outstanding performance that has greatly aided in our work and more importantly, with our shop safety. Thank you Koike
