The legacy MOPPET valve design makes field repairs simple and economical. Sealing elements and springs are combined with a seat in a convenient cartridge that can be removed and replaced in minutes with a hydraulic press. Repairs can be performed in the field, with no lapping, grinding or machining required.
Elements and springs are replaced each time a valve is serviced, but cartridges are replaced only when damaged or worn. Incremental replacement reduces costs and helps maximize the utility of each component. MOPPET cartridges are precision-manufactured from 17-4 stainless steel for exceptional corrosion resistance on critical seating surfaces.
The efficiency upgrade of the MOPPET removes the cartridge design to optimize flow area and clearance volume in the valve.
