The Armstrong Circuit Balancing Valves (CBV) provide precise flow control through multi-turn range adjustment and globe valve design.

If checked, cbv valve pre-formed insulation to be pro- vided to meet code requirement of flame spread rating of 25 or less and a smoke development rating of 50 or less

2021年1月25日 · 1.4 cbv angle-style valves are designed to replace piping elbows. 1.5 Metering ports and body plugs may be interchanged for improved accessibility. 2.1 Tighten all bolts evenly in standard star pattern. When used with a raised face flange, there will be a gap be-tween the faces on the outer flange diameters.

Prices for APO-18, 20, 24 & 30 available upon request. All APV and APO units include a chained metal color ID tag marked with unit number, GPM and meter reading. Also included is a set of 1/8" nipples, valves & disconnects.

Straight and Angle Sizes 2½” - 12" n EPDM not suitable for oil service. INSTALLATION Generally locate the valve five pipe diameters downstream from a fitting; with two diameters downstream from the balancing valve free from fittings. If a balancing valve is located downstream from a circulation pump, allow a distance of ten (10) diameters

Balancing Basics Circuit balancing valves (CBVs) have been used for many years as an effective means of ensuring occupant comfort in buildings. Heating and chilled water systems are designed to deliver the correct amount of heated or chilled fluid to every part of a building’s HVAC system.

Generally locate the valve five pipe diameters downstream from a fitting; with two diameters downstream from the balancing valve free from fittings. If a balancing valve is located downstream from a circulation pump, allow a distance of ten (10) diameters between the pipe and balancing valves (as illustrated below).
