Metal manifolds

Stainless-steel manifold assembly, 1" with flow meter

Stainless-steel manifolds feature isolation valves, balancing valves with flow meters, supply and return ball valves with temperature gauges, and come fully assembled, ready for installation. Targeted for commercial and residential radiant heating and cooling applications, the manifolds are available in 1" and 1¹⁄₄" sizes. All manifold supply and return ball valves feature 1" NPT thread except for 1¹⁄₄" manifold assemblies with 8, 10 and 12 loops which feature 1¹⁄₄" NPT. Note: The 1¹⁄₄" manifolds with 2 through 7 loops are strategically designed with 1" NPT ball valves to avoid adding extra costs while maintaining the maximum flow of the manifold assembly.

TruFLOW Classic assemblies with balancing and isolation valves

TruFLOW manifold assemblies with balancing and isolation valves come fully assembled and ready for installation. The assemblies are shipped with the appropriate number of TruFLOW manifold actuator adapters (A2630028). Maximum recommended flow to the manifold is 14 gpm for Jr. (1" barrel diameter) and 21 gpm for Classic (1¹⁄₄" barrel diameter).

TruFLOW Jr. assemblies with balancing and isolation valves

TruFLOW manifold assemblies with balancing and isolation valves come fully assembled and ready for installation. The assemblies are shipped with the appropriate number of TruFLOW manifold actuator adapters (A2630028). Maximum recommended flow to the manifold is 14 gpm for Jr. (1" barrel diameter) and 21 gpm for Classic (1¹⁄₄" barrel diameter).

TruFLOW Jr. assemblies with balancing valves and valveless manifolds

TruFLOW Jr. assemblies with balancing valves and valveless manifolds come fully assembled and ready for installation. The manifold body (1" barrel diameter) ends have R32 unions and the loop outlets have R20 male threads. Maximum recommended flow to the manifold based on manifold body diameter is 14 gallons per minute (gpm).

TruFLOW Jr. return manifolds with isolation valves

TruFLOW Jr. return manifolds with isolation valves are used with either the TruFLOW Jr. modular manifolds with balancing valves or the TruFLOW Jr. modular valveless manifolds to complete the manifold set. The TruFLOW Jr. return manifolds with isolation valves allow for manual isolation of the individual loops on the manifold. Manifolds are available in 2- to 4-loop configurations depending on model. The manifold body (1" barrel diameter) ends have R32 threads as shown in the picture. Maximum recommended flow to the manifold is 14 gpm.

TruFLOW Jr. supply manifolds with balancing valves

TruFLOW Jr. supply manifolds with balancing valves are used in conjunction with either the TruFLOW Jr. modular manifolds with isolation valves or the TruFLOW Jr. modular valveless manifolds to complete the manifold set. The TruFLOW Jr. supply manifolds with balancing valves allow manual flow balancing of the individual loops on the manifolds. Manifolds are available in 2- to 4-loop configurations depending on model. The manifold body (1" barrel diameter) ends have R32 threads as shown in the picture. Maximum recommended flow to the manifold is 14 gpm.

TruFLOW Jr. valveless manifolds

TruFLOW Jr. valveless manifolds are used with either the TruFLOW Jr. return manifolds with isolation valves or the TruFLOW Jr. supply manifolds with balancing valves to complete the manifold set. TruFLOW Jr. valveless manifolds do not feature flow balancing or isolation capability. Manifolds are available in 2- to 4-loop configurations depending on model. The manifold body (1" barrel diameter) ends have R32 threads as shown in the picture. Maximum recommended flow to the manifold is 14 gpm.
