Plastic Noncontact Flow-Adjustment Valves

With no metal parts, these valves are often used for noncontact flow adjustment in wet conditions and harsh environments. All press down on the outside of tubing to adjust flow without contacting the process media. They can be used with any media that’s chemically compatible with your tubing.

Valves with a closed body securely hold tubing in place.

Dial handles are marked with a 1 to 10 mm scale that allows you to make repeatable adjustments.

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.
