Complete line of pressure gauge cocks and valves. It is available a cheaper range in brass for low pressure or a range for operational use where there is high temperature and sharp temperature excursions. These are normally applied to tubing, machines or systems where it is necessary to be able to regulate or cut-off supply or discharge fluid flow.
