MOPPET® valves provide outstanding reliability, in even the most demanding service. They deliver consistently longer run times and reduce total life cycle costs. Now, further optimization of the gas flow provides up to 15 percent higher efficiency.
A MOPPET valve consists of a series of small, identical sealing elements (discs) that operate independently of each other, helping to disperse liquids and debris and providing outstanding resistance to damage and wear.
Each element is made of durable, lightweight thermoplastic material, which reduces impact inertia. In addition, the thickness of the elements and small center-line diameter make them extremely stiff and resilient to high impact forces caused by extreme pressure, driver speed, or the presence of incompressible matter in the gas.
Building on the proven success of the MOPPET valve in severe service environments, Cook Compression has introduced new features to improve efficiency:
Springs and spring pockets in MOPPET valves are designed for extended performance in dirty service.
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.
