Industrial Applications
✅ Geothermal Reinjection Units
Used to regulate the reinjection of geothermal fluids post energy extraction. Top entry valves maintain accurate pressure control and endure corrosive and thermal stresses.
✅ PIG Traps
Top entry full bore valves offer an ideal flow path for inserting or retrieving pipeline inspection gauges (PIGs) under high-pressure conditions.
✅ Surge-Relief Skids
Due to their quick-actuation and sealing capabilities, these valves effectively manage pressure surges, opening and shutting automatically when preset levels are reached.
Product Range & Design
Eastern United’s top entry trunnion-mounted ball valves range from ½” to 60” (DN15 to DN1500), available in full bore or reduced bore. Engineered for low operating torque, these valves ensure smooth operation even under extreme working conditions.
🔄 Operator Options: Pneumatic, Hydraulic, Gas Actuators, or Manual Gear Operated.
