2230/4430 2-Way Temperature Sensing Valve - 1

2-Way Temperature Sensing Valves 2-way valve which is opened by increasing temperature of engine cooling water, lubricating oil, high pressure gas or other fluids. The 2230/4430 can also be used to sensing high bearing or packing temperatures. Opening of the valve vents control pressure from an AMOT Mater Safety Control such as Model 2800 or 4261, and protects the engine, compressor, pump, gear case, and industrial machinery from over-temperature. Typical applications • Jacket water • Discharge gases Type 2230 Valve Type 4430 Valve • Bearings or packing (Brass) (Stainless Steel) • Compact, rugged design • Factory set, field adjustable • Compatible in hydraulic or gas systems • Easy maintenance; few moving parts • Compatible with complete AMOT shutdown • No electricity required; failsafe • No wires to break or corrode • Viton seals standard • Brass (2230) or stainless steel (4430) • Temperature setting available from 30°C to 118°C • Maximum pressure at the IN Port is 8.6 bar • Maximum internal pressure on the temperature sensing element is 551 bar (800 psi)

2-Way Sensing Valves - Models 2230/4430 Operation Model 2230/4430 operation is simple and straight forward. As the temperature of the sensed fluid increases, wax enclosed in the valve’s temperature sensing element expands against a push rod, which in turn unseats a valve allowing flow to travel from the valve’s IN port and out the valve’s OUT port. For visual indication that the temperature valve has tripped, use AMOT Model 4054 Trip Indicator. Model 2230/4430 Temperature Valves are set at the factory, and the trip temperature is stamped on the valve body. The valve will start to bleed...

2-Way Sensing Valves - Models 2230/4430 Before installing the Model 4430 it is advisable to run a 23"/32" dia. tap drill through the pipe fitting in which the unit will be placed. Some commercial fittings are not tapped deep enough and the threads may damage the valve's temperature element cup. Apply a quality thread sealant such as Loctite™ Pipe Sealant to pipe thread connections. Avoid introducing the sealant or other contaminants into the system. On a system using lubricating oil for control pressure, the vent port is connected to the engine oil sump. If natural gas is used, the vent...

2-Way Sensing Valves - Models 2230/4430 Refer to cut-away view below. To adjust the temperature seting of the 2230/4430, place a screwdriver through the IN port and in the slot of Adjusting Screw (Item 10). To RAISE the temperature setting turn the screw counterclockwise, to LOWER the setting turn the screw clockwise. One turn equals about 10°F. When changing the tripping temperature be sure that the valve is not adjusted beyond Service Parts Refer to cut-away view to the left. Cut-away View Cut-away View Dimensions in inches (mm).
