Threaded Balancing Valves
- Valve Type: Ball
- For Use With: Water
- Seal Material: EPDM Rubber
- Specifications Met: CSA Certified
Thread these balancing valves onto pipe—they help you measure the pressure differential across the valve as well as change the flow rate to components in your system. Sometimes called circuit setters, they’re used in HVAC systems and other systems that require even flow distribution. To see what percentage they’re open, there’s an arrow on these valves that’s connected to their measuring plate. Readout ports on both sides let you attach flow measurement tools, such as pressure gauges and probes, which help you track how much the valves reduce flow. Open these valves to a saved percentage by using their memory shutoff function.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Solder-Connect Balancing Valves
- Valve Type: Ball
- For Use With: Water
- Seal Material: EPDM Rubber
- Specifications Met: CSA Certified
Attach these balancing valves using solder—they help you measure the difference in pressure across the valve and adjust the flow rate to system components. Also known as circuit setters, they’re often used in systems that need an even distribution of flow, such as HVAC systems. To check what percentage they’re open, there’s an arrow on these valves that’s connected to their measuring plate. There are readout ports on both sides for connecting flow measurement tools, such as pressure gauges and probes, which help you track how much the valves reduce flow. Use the memory shutoff function to open them to a saved setting.
Flow coefficient (Cv) is the amount of water (in gallons per minute) at 60° F that will flow through a fully open valve with a difference of 1 psi between the inlet and the outlet.

Motor-Driven On/Off Valves with Solder-Connect Fittings
- Valve Type: Ball
- For Use With: Water, Steam
- Seal Material : Buna-N Rubber
- Specifications Met: C-UL Listed, UL Listed
Slide copper pipe into the solder-connect fittings on these valves and weld for a strong, permanent connection. They’re often used for remote on/off control in heating and cooling systems. All operate on electricity to automatically start and stop flow. Valves do not require a minimum pressure drop between the inlet and the outlet for operation. They are normally closed unless actuated. All are standard port, so they slightly restrict flow.
The actuator is directly mounted to the valve body to minimize movement and reduce wear. The manual override allows you to operate the valve during power outages.

Air-Release Valves for Water and Coolant
and Female
Outlet
These valves are often used to remove air pockets in cooling and heating systems to maintain consistent flow and prevent water surges that can damage equipment. All have a vented relief port to exhaust discharge directly.
Valves with female/male inlets have an inlet with both male and female threads, so they can be connected to both male and female adapters and equipment ports.
