Modulating Valve Fig. 700, Jenkins Modulating Valve -' A notable improvement over present day modulating valves lies in Fig. 700 Jenkins Modulating Valve which has a vertical instead of a horizontal seat, affording these particular advantages: Foreign matter cannot lodge on seat and prevent tight closing of valve. Vacuum is under disc holder, which is fitted with Jenkins Rubber Composition Disc, with a tendency to draw disc to the seat. Spring holds disc against seat. Seating and tightness do not depend on threaded spindle that needs to be turned down tight to prevent leakage. This valve cannot leak around spindle.

Iron Body Globe, Flanged 810 Fig. 386, Iron Body Gate, Screwed A Valves New York Air Valve Corporation 476-478 Broome Street New York The "Air-Out" Line SYPHON THERMOSTATIC NON-ADJUSTABLE "Air-Out" valves, for eliminating air from steam radiators, operate by the expansion of a phosphor bronze diaphragm, soldered on the bottom of a brass float, containing a volatile liquid. This float is large in size, allowing ample capacity for the necessary pressure to operate the diaphragm. The seating pin at the top of float is made from nickel silver, as called for in United States Government specifications for Air Valves. Verdigris will not form on nickel silver--corrosion at the vent post is therefore reduced to a minimum. We do not use a "stamped out " base. .Our bases are heavy bronze castings, inr 'one piece, with no soldered parts to break off. Made also in straight pattern, threaded 7 and % in. for quick venting of cellar mains and risers. The best valve money and experience can produce and sold at reasonable prices.
