High Pressure Trunnion Ball Valves
Positive Shut-Off Performance for Critical High-Pressure Systems
Ped-lock Trunnion Style High-Pressure Ball Valves are engineered to provide reliable quarter-turn isolation in demanding liquid and gas applications. Designed for operating pressures up to 20,000 PSI (1,379 Bar), these valves feature a trunnion-mounted ball design that minimizes operating torque, reduces seat wear, and ensures dependable sealing performance under high-pressure conditions.
Available in both 2-Way and 3-Way configurations, these valves are ideal for hydraulic systems, gas distribution networks, chemical injection skids, pressure testing equipment, and process control applications where safety, reliability, and performance are critical.
Available Configurations
2-Way Trunnion Ball Valves
Designed for positive shut-off service with simple quarter-turn operation. The trunnion-supported ball provides enhanced sealing integrity and smooth operation, even under extreme pressure conditions.
3-Way Trunnion Ball Valves
Available in both 180° Switching and 90° Diverter configurations, allowing operators to divert, isolate, or alternate flow paths within high-pressure systems.
