Thrush offers a full range of valves to meet the needs of the heating and cooling industry. Thrush has the resources to obtain various valves listed below, but not limited too, that allow us to service all your requirements.
Thrush's Quad-Chek Valves are a four-function flow control valve and versatile enough to fill all hydronic heating needs. They can function as a Flow Control Valve, Balancing Valve, Open Port Valve, or Shut-Off Valve.
Thrush's Dual Control Valves provide automatic pressure relief and filling of hot water heating systems. Thrush's Automatic Fast Fill Valves are low pressure reducing valves designed to maintain proper water pressure in closed-loop heating systems or any closed piping systems.
Thrush's Regulating Valves are built for installation in a system where liquid or air pressure must be reduced and a lower pressure maintained within satisfactory limits. The valves 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. Thrush's Boostrol® Valve is utilized on Thrush's PressurizersTM. The Boostrol® Valve regulates and maintains a constant pressure regardless of fluctuating supply pressure or changing flow demand on a PressurizerTM. It is field adjustable to meet any application.
A Purge Valve is designed to purge air from a hot water heating system. Balancers are precision-machined valves designed to control the flow of liquids. Triple-Duty Valves combine balancing, check, and shut-off in a single valve. Thrush's Relief By-Pass Valve is ideal for small boilers, heating systems and unfired pressure vessels. Selector Valves simplify make up of return main, balancing of circuits and mixing water for radiant heating. It can vent in horizontal or vertical position.
A Universal Replacement (UR) Valve is reliable and easy to install in heating systems. A relay is included on the circuit board under the valve cover. LED's indicate power to valve and zone thermostat calling for heat. The soft-close, filtered power circuit eliminates humming and water hammer.
The AA and AB Zone Valves provide comfort and economical multi-zone heating controls. The AA Zone Valves are normally installed with Multi-Zone Controller new boilers. The AB Zone Valves are installed on hot water lines near the baseboard enclosure.
Steam Control Valves is an externally piloted temperature regulator for large-capacity applications. A Ball and Check Valve with rotating flange and optional check valve is designed for the isolation of any circulator.
