製品の説明
A800 High-Precision Differential Pressure Control Valve (DPCV)
Intelligent Pressure Management Solutions
The A800 Differential Pressure Control Valve is a sophisticated hydraulic solution designed to maintain a constant pressure differential between two points in a circulating system. It is the optimal choice for addressing:
  • System Instability: Eliminating noise and flow fluctuations in HVAC and cooling circuits
  • Energy Inefficiency: Optimizing pump performance by preventing excessive pressure build-up
  • Equipment Protection: Safeguarding sensitive heat exchangers and chillers from pressure surges

Core Technical Specifications
Feature Technical Detail / Value Proposition
Model Series A800 Differential Pressure Pilot-Operated Valve
Control Logic Independent Diaphragm-Actuated Differential Pilot
Monitoring Components Integrated Dual Pressure Gauges (Upstream/Downstream)
Fine-Tuning Capability External Adjusting Screw for Precise Set-point Calibration
Isolation Mechanism Auxiliary Mini-Ball Valves for Gauge maintenance
Connection Standard ANSI / DIN / JIS Heavy-Duty Flanged Ends

Why Engineers Prefer the A800 Series
  • Pilot-Operated Precision: Unlike direct-acting valves, the A800 uses a pilot system that responds to minute pressure changes, ensuring a stability margin within ± 2% of the set value
  • Integrated Monitoring Hub: Built-in dual gauges allow for real-time visual diagnostics without requiring additional pipe tapping
  • Dual-Chamber Design: The reinforced diaphragm chamber provides a smoother response and prevents the "water hammer" effect during rapid flow changes
  • Robust Protective Coating: Industrial-grade blue epoxy prevents cavitation damage and external corrosion in damp mechanical rooms

Authoritative Use Cases
  • District Heating/Cooling: Balancing supply and return pressure in large-scale HVAC loops
  • Automatic Pumping Stations: Acting as a bypass control to maintain pump curve efficiency
  • Multi-Zone Irrigation: Ensuring constant pressure across varying elevations and distances
