3/8 spring loaded valves

Valves arrived but they took a while to come,also missed the courier as I did not no they we coming so they went back to depot delayed it a bit more.

Mr. S Scrace

A very good quality product ! It would be good to “adjust” or replace the spring pressure.

Good fitting valve

Ideal for my purposes after I've reduced the power of the spring. I'm using steam at 120lbs/q inch. I need to put minimum effort into operating the valve
