Three way thermostatic valve
The AMOT model 6B steel and stainless steel thermostatic valve may be mounted in any position and uses the proven expanding wax principle to actuate the 3-way temperature element assemblies.
The valve is ideal for use in the lube oil skid building sector where demand has increased due to higher design pressures needed in the complete module, as well as the introduction of legislative driven specifications.

Amot BR-valve model code example: (See also table in data sheet p. 8)
3BRCB1000100AA: 3'' valve with manual override (BO), cast iron(C), flange PN10 (B), 100°F element (100), standard element without override with buna N/Nitrile seal(01), leak hole size (0), leak hole number (0, no customer customization (AA)
33BRCB1000100AA: same as above, but with three elements
4BRCB1000100AA: same as above, but 4'' valve
4BRCB1250100AA: same as above, but with 125°F element
The valve is supplied with the temperature element assemblies factory-set to the nominal temperature setting. Temperature is sensed at Port A which remains open to Port B (bypass) until the fluid temperature reaches a point 5 - 10°F (3 - 6°C) below the nominal setting. As the temperature continues to rise, the sliding valve moves to close off Port B and open Port C (connected to the cooler or heat exchanger) Port B is fully closed 8 - 10°F (4 - 6°C) above the nominal setting. The valve continually modulates the fluid flow to maintain the nominal temperature. For optimum control the system should be sized so about half the total fluid flow is passing through the cooler at full load.
