• Bonnets are easily interchangeable: When closed, remove forks and slide bonnet off of ram change rods

A safe economical ram change design that keeps bonnet stroke short:

• Bonnet weight is evenly distributed between telescoping rods and fixed external pipe

Proprietary contoured ram bore relief for extended seal life and resistance free removal:

• In the closed position seals are energized and ram is supported
• In the open position top and front seals are relaxed

Maximum shear force is achieved without a tandem booster

• Floating shear piston will not overload the ram seals
• Internal lock saves strength
• Hydraulic Disconnect
• Anti-rotation via ram slot
