4064 Differential Pressure Valve

SKU 4064

AMOT Model 4064 is used for sensing limits of increasing or decreasing differentials. Some applications include gas compressor installation to shut down the engine in the case of overloading, as well as sensing excessive pressure drop through a filter, indicating filter clogging.

Features and Benefits

  • Settings from 8 - 3500 psi
  • Gulfproofed, anodized aluminum construction
  • Accepts hydraulic or pneumatic signals
Specifications
Body material: Gulfproofed anodized cast aluminum
Internal parts: Steel and aluminum
Valve seat and seals: Viton
Diaphram material: Viton Buna N/Nitrile
Piston material: Stainless steel

Max. valve pressure port A

5.5 bar 80 psi
Net weight 2.5 kg 5.5 lb
Shipping weight (appx.) 3.0 kg 6.5 lb
Applications
  • Compressor Suction / Discharge Pressure Sensing

  • Detecting Rod Overload

  • Detecting Clogs Across Filters, Separators, Scrubbers, and Membranes

  • Pump Differential Pressures,

  • Detecting Pump Cavitation, Fluid Leakage, Damage

Operation

Model 4064 is used for sensing limits of increasing or decreasing differentials. At the set differential, safety control system pressure coming into port A will vent out of port B. A typical application would be on a gas compressor installation. The gas discharge line would be connected to port P1, and the suction pressure line would be connected to port P2. If the pressure at P1 exceeded that of port P2 by the set amount, (indicating compressor connecting rod overloading), port A would vent and shut down the engine.  Another application would be to sense excessive pressure drop through a filter, indicating filter clogging.
