(7) Universal Replacement Valve is an innovative replacement valve that is reliable, fail-safe, and easy to install, simple two-wire connections make it a quick installation. The Zone control stays normally open if the power goes off, the hot water can still flow.
Thrush Dual Control valves provide automatic pressure relief and filling of hot water heating systems. All Dual Control valves are factory set at 30 psig for the relief and 12 psig delivery pressure for filling. These are non-adjustable relief valves with a build in strainer. They can be used to maintain air or light oil pressure on special applications and can be installed in cold or hot water lines up to 200°F.
(4) Thrush Quad-Chek valves are made from quality cast iron. They stop overheating from gravity circulation in hot water heating system by means of positive closing, precision machined, brass-to-brass seat and check weight. The vertical lift action of the check weight produces a smooth floating application of this unit. Thrush Quad-Chek valves can be installed as an angle, horizontally, or by-pass valve, for system loop temperature balancing. The vertical lifting stem design permits several modes of operation including preventing overheating from gravity circulation, allowing balancing of flow in circuits, allowing gravity circulation or draining of the system, and permitting isolation of system for maintenance.
(4) The Thrush Purge Valve is designed to purge air from a hot water heating system. The diverter stops flow prior to the valve, forcing the water to move
in one direction allowing air in the piping to be purged.
The diverter packing is heat resistant and does not have to be removed when sweating the Purge Valve to the piping.
(4) Thrush regulating valves are built for installation in systems where liquids or air pressure must be reduced and a lower pressure maintained within satisfactory limits. They are especially designed for regulating reduced pressures on domestic water supply systems where city water pressure is high. They may be installed in either hot or cold water lines. Pressure regulating valves maintain the pressure setting only at no flow by nature of design.
(5) Repair kits for the High Pressure Regulating Valves include springs, diaphragm, metal seat, composition seat, screen, and gaskets. Also where applicable, relief by-pass.
(5) Universal Vent Tees come standard with a manual vent however you can save installation time if you change from manual to automatic venting in seconds. Simply remove the manual vent and replace it with an automatic type.
(2) Adjustable Vent Tees come standard with a manual vent however you can save installation time if you change from manual to automatic venting in seconds. Simply remove the manual vent and replace it with an automatic type.
(10) Dip Tubes will remove air from the system connection on the boiler as well as replace boiler fittings at the flow valve on continuous operation systems. These are available in sizes ranging from 1” to 1.5” and 6” or 12” length and 2” to 3” and 8” or 14” in length.
(2) Selector Valves are used for balancing of circuits and mixing water for radiant heating. They are a simplified make up of a return main also venting in the horizontal or vertical position.
(9) Designed to route air that has been separated
(with an Air Purger or Air Separator) from the
system back to the compression tank and to
restrict gravity flow of water between the tank
and system.
(4) Thrush Balancers are precision-machined valves designed to control the flow of liquids.
Balance is indicated by the slot location. The stem controls the valve diverter to control the flow.
The diverter packing is heat resistant and does not have to be removed when sweating the Balancer to the piping.
