Specifically designed for high pressure applications, incorporating proven techniques in flow-stream contouring for higher capacities and in valve trim design for reliability in severe applications.
Improved Cage Design: Drilled-hole cages, offering excellent strength and additional resistance to destructive vibration, are standard. Special materials of construction are readily available.
High Capacity, Control Flexibility: Careful consideration of aerodynamic and hydrodynamic principles in the design of the flow stream passages results in 30 to 40 percent higher capacity than conventional valves with comparable port sizes and travels. Special cage characterization can be supplied to satisfy almost any combination of flow and noise or cavitation abatement. Cage characterization and efficient flow passages provide close control for low flow, high pressure drop and high flow, low pressure drop conditions.
Operational Economy, Reliable Control, Easy Maintenance: Balanced trim constructions reduce forces acting on the valve plug, reducing actuator thrust requirements and permitting the use of smaller actuators. All aspects of the control valve are designed, built, and tested to assure performance and reliability. The bonnet lifts off to allow trim access. The separate seat ring and cage allow parts removal and maintenance.
Increased Pressure/Temperature Ratings, Long Trim Life, Excellent Stem Sealing and Shutoff: EH and EHA valves with buttwelding end connections have Intermediate Standard Ratings. With nondestructive testing, these valves can conform to ASME Intermediate Special Ratings, which allow even higher pressure/temperature applications. Hardened materials of construction for the cage, valve plug, cage guiding, and other trim parts are standard for all applications, providing excellent wear resistance. Use of the metal C-seal permits Class V shutoff up to 593 C (1100 F). HIGH-SEAL packing systems provide excellent sealing to conserve valuable or hazardous process fluid and to protect against the emission of hazardous or polluting fluids to atmosphere.
