Low Pressure Valve Model 4047 Overview AMOT Model 4047 is used as a 2-way or 3-way high capacity, low pressure valve for settings from 0.007 bar (0.1) psi falling to 0.77 bar (11.2 psi) rising over several ranges. Applications include sensing low pressure low pressure gas, water, fuel, oil, or for liquid level sensing and control. By piping to the vacuum port, the valve can be used to sense vacuum pressure from 0.007 bar (0.1) psi falling. The 4047 can detect overload on gas engines by sensing the vacuum pressure in the intake manifold. Typical applications • Sense low pressure or vacuum of water, air, natural gas, oil and more Detection of overload on gas engines Sensing of vacuum intake air manifold 3-way valve has balanced force design Pressure can be applied at any port Buna N (Nitrile) “tadpole” seals are easily replaced Bubble-tight seals with center dead spot (no port overlap) Gulfproof finish standard

Low Pressure Valve - Model 4047 Valve to open on rising pressure Port 1 must be plugged. Rising pressure will open Port 2 to Port 3 above the trip point. Valve to open on falling pressure Port 3 must be plugged. Falling pressure will open Port 2 to Port 1 below the set trip point. Valve operation for 3-way action is identical with that for 2-way except that there will be no plugged diaphragm housing Valve spool diaphragm Buna N (Nitrile) Maximum operating ports. On valves set to trip on rising pressure, Port 1 will open to Port 2 until just below the trip point. Port 3 will open to Port 2...

Low Pressure Valve - Model 4047 Maintenance Properly applied and installed, Model 4047 requires minimal maintenance. Unless leakage or other problems are noticed sooner, an inspection of the units at yearly intervals is adequate to detect and make provision for normal wear and preventative maintenance. It is recommended that the valve be checked monthly if possible for proper functioning by simulating an unsafe condition. Service kits STAMP "P" Seal ring Seal ring
