For Safety, Sureness of Operation and Durability FOSTER PRESSURE REGULATORS FOR STEAM HEATING SERVICE

(Classes "Q" and "QH"?) lead the way. Designed especially for steam heating, and suitable for vacuum systems, for delivery pressure of from 1 to 15 lbs.

We make several types of pressure regulators-those shown in the illustrations here were designed particularly for steam heating service, and they are ve y sensitive, reliable, high grade in every · particular and superior to other makes in construction and workmanship. There are no weights or close fitting pistons, and are easily adjusted to the desired pressure between 1 and 15 lbs. Made in sizes 34 inch to 2 inches inclusive, composition body. Larger sizes are fitted with composition renewable seats.

for High Pressure

Unexcelled in workmanship, material and design. Made with metal-to-metal joint between top and bonnet, with another leakproof joint around the valve stem. The disc is held in place by a bronze noncorrosive spring, and the tension at all times holds the composition disc against the upper seat, making leakage impossible under all circumstances. The disc holder, which holds the composition disc forming the lower seat in the valve, is spun on the disc carrier in such a way that it may revolve, and allows the carrier to take its seat properly when closed.

The Syracuse Packless Standard Globe Valve is of bronze

and is especially adapted for high pressure steam systems. Send for "Inside Information on The Syracuse Packless Radiator Valve"

OW IS THE TIME to get after that unsatisfactory heating system.

Tell us your troubles and we will advise you how to overcome them. In most cases an "ECONOMY” AUTOMATIC CONDENSATION PUMP AND RECEIVER is all that is required.

These outfits consist of an expansion tank, an auto

matic switch and a centrifugal pump automatically

operated by an electric motor.
They stimulate circulation by drawing condensation

through system, venting the air and returning the

water to the boilers at high temperature.
They eliminate snapping and cracking in the radi-

ators and pipes.
They are a stimulant and governor to the entire

system and a great saver of fuel.
Being automatic they require no attention other than

an occasional oiling.
The operation is equally satisfactory on either high or
low pressure systems.
