WATTS Mixing Valves

Used with water heaters to mix hot and cold water for a safer outlet temperature and to prevent scalding & thermal shock. Follow ASSE and CSA standards and have a maximum flow rate of 23 gpm

Features

• Watts mixing valves have integral check valves and filter gaskets in both the hot and cold water inlets to prevent cross flow and ensure that water flows in one direction only.
• The double throttling design responds quickly to changes in water temperature.
• The solid wax hydraulic principle thermostat regulates both hot and cold water and is designed to provide consistent mixing of hot and cold fluids.
• Heat traps are used in thermostatic valves to reduce convection loss (also known as thermosiphon) and thus, increase system efficiency.
• In the event that the cold water supply is compromised, the flow of mixed water is safely restricted.
• Sweat or threaded connections are available.

Watts Master Mixing Valves

• These thermostatic mixing valves are used to mix hot and cold water to bring down the service water to a safe and comfortable level for the building's distribution piping system.
• They feature a copper paraffin thermostat to sense and adjust the outlet temperature, a single-seat design and a vandal-resistant locking mechanism to prevent tampering with temperature settings.
• The interior walls of these units are made of polysulfone that resists excessive heat, corrosion and liming.
• They have a lead-free brass construction for excellent corrosion resistance and are capable of withstanding temperatures up to 180 degrees F.

Powers Mixing Valves

• HydroGuard Series mixing valves are designed to blend hot and cold water by utilising an advanced thermal actuation technology for tepid water delivery to emergency fixtures.
• They include a unique internal cold water bypass and check valve to ensure the delivery of cold water flow in the event of hot water failure.
• Power's valves feature a booster funnel to channel water flow directly around the paraffin actuator helps improve response time and enhances flow control.
• They are also included with triple-duty check stops to prevent cross-flow and provide complete isolation for repair and maintenance.

Working Mechanism

• When tempered water is used, a thermostat in the valve's mixing chamber detects the outlet temperature and automatically positions a seat assembly, which controls the flow of hot and cold water supplied to the mixing chamber.
• If the temperature of the mixed outlet rises, the thermostat will expand, moving the seat assembly to allow the cold water inlet port to open more fully while restricting the hot water inlet port.
• If the mixed outlet temperature drops, the thermostat contracts, moving the seat assembly to allow the hot water inlet port to open more fully while restricting the cold water inlet port.
• In both cases, the temperature of the mixed outlet water is automatically and continuously maintained at the preset temperature within the valve's tolerances.
• When the cold or hot water supply fails, the seat assembly moves to an extreme position, cutting off the hot or cold inlet water port.
• A mechanical adjustment allows you to select the desired outlet water temperature within the valve's range.
