주요 이점 및 장점
-
High Capacity Axial Flow: The streamlined internal flow path produces exceptionally high capacities, allowing for smaller valve sizes to handle massive flow requirements compared to traditional globe-style regulators.
-
Fast Speed of Response: Specifically designed to meet the stringent response requirements of turbine startup and rapid load changes, ensuring the fuel supply matches the dynamic needs of power generation equipment.
-
Accurate and Sensitive Control: Molded pilot diaphragms create a narrow proportional band, while direct registration of outlet pressure on the main diaphragm provides superior control sensitivity.
-
Absolutely No Atmospheric Bleed: The pilot-operated system is environmentally friendly and efficient, bleeding 100% of the loading gas back into the downstream system to eliminate emissions.
-
Tight, Positive Shutoff: A specialized throttling-sleeve design paired with a Polytetrafluoroethylene (PTFE) seat in the body ensures a bubble-tight seal, even in high-pressure standby conditions.
-
Superior Debris Resistance: The metal plug is shaped to deflect particles and debris away from the soft-set, providing excellent erosion resistance and ensuring a long service life in severe service applications.
-
Space-Efficient Design: Because the actuator spring is integrated into the main valve design, the Type 310A requires significantly less installation space than other regulators of comparable capacity.
-
High Turndown Capability: The oversized diaphragm and unique piloting system allow the regulator to maintain stable control across a vast range of flow demands, from minimum pilot light levels to full turbine load.
기술적 특성
-
Main Valve: Type 310A high-pressure axial flow valve.
-
Pilot Assembly: Includes one Type 32A pilot mounted directly on the main valve for pressure reducing or wide-open monitoring applications.
-
Seating Material: PTFE (Teflon) for chemical compatibility and high-integrity sealing.
-
Application Flexibility: Optimized for high-pressure gas reduction where speed and volume are the primary performance drivers.
-
Registration: Internal registration of outlet pressure for simplified piping and installation.
적용 분야
The Type 310A is the preferred regulator for critical fuel gas delivery systems where a failure in speed or accuracy could result in a turbine trip. It is also widely used in high-pressure distribution headers for large industrial complexes.
