More'* rattl economy In temperature control* Because Spence Temperature Regulators are designed to limit heater steam pressures to an adjustable maximum, the need for a separate' reducing valve is completely eliminated.. The. Spence Regulator takes steam directly from the boiler or high pressure line, reduces, the pressure and regulates the flow as required to maintain a constant temperature output from the heater. This means one relatively small combination pressure and temperature regulator replaces a reducing valve of the same size and a larger temperature regulator. Practically the entire cost of the large separate temperature regulator is saved. And, the total saving would also include sthercostjof^ Vvalvt bypass along with all wT^is*d^&nu.e^urB^us^hg|Of the reasons for the thouanndsa^t^^elinsgllmibnji thioughout powm irriCMKR^j SCHSM8EI 1953
