4064 Differential Pressure Valve

Product catalog summary

Overview
The AMOT Model 4064 Differential Sensing Pressure Valve is designed to sense limits of increasing or decreasing pressure differentials. It is commonly used in gas compressor installations to prevent engine overloading and to detect excessive pressure drops indicating filter clogging.

Key Features and Benefits

Pressure settings range from 0.55 to 241 bar (8 to 3500 psi).
Constructed from Gulfproof anodized aluminum.
Compatible with hydraulic or pneumatic signals.

Typical Applications

Compressor suction and discharge pressure sensing.
Detection of rod overload, clogs across filters, separators, scrubbers, membranes, pump cavitation, and fluid leakage.

Specifications

Body Material: Gulfproofed anodized cast aluminum.
Internal Parts: Steel and aluminum.
Valve Seat and Seals: Viton.
Diaphragm Material: Viton or Buna N.
Piston Material: Stainless steel.
Maximum Valve Pressure Port A: 5.5 bar (80 psi).
Net Weight: 2.5 kg (5.5 lb).
Shipping Weight: Approximately 3.0 kg (6.5 lb).

Operation
At the set differential, the safety control system pressure entering port A will vent out of port B. For example, in a gas compressor installation, if the pressure at port P1 exceeds that of port P2 by the set amount, indicating compressor connecting rod overloading, port A will vent and shut down the engine.

Installation Factors

The valve can be mounted in any position, typically with the vent connection at the bottom.
Use a quality thread sealant for piping connections, ensuring it does not enter port passages.
Minimum tubing size for safety control system piping is 1/4" O.D.
If sensing liquid pressures with pulsations, use an orifice or dampening device to protect diaphragm models.

Ordering Information
To order, specify the model number based on the pressure range and reset requirements. Provide the exact operating characteristics, including the pressure at fixed and variable ports and whether the trip occurs on increasing or decreasing pressure.

Differential Sensing Pressure Valve - Model 4064 Operation 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. Model 4064 is supplied by AMOT with the differential pressure setting compatible for a specific working...
