Rp123000.00
The Fisher Types 634 and 634M high-pressure shutoff valves are designed to provide effective overpressure protection by containment. The Type 634 shutoff valve, featuring internal pressure registration, is typically installed between a pressure-reducing regulator and downstream equipment. In contrast, the Type 634M shutoff valve, with external pressure registration, requires a control line and is installed upstream of a pressure-reducing regulator.
