Flow control valves

Mail4tommo

Can you use spring check valves in place of a "standard" b & g flo control? Also is there any other options besides the B & G's?

Thank you in advance

usually unless the circulator is marginal, the weighted check has a bit less resistance than the spring check. the nice thing about most of the wighted check designs is they can be manually opened to purge and bleed the system.

taco, b&g, watts, and caleffi make flow check valves(caleffi look like they are only spring flow checks)

you can put a flow check in the flange of most newer circulators too

Caleffi had a spring check with a manual lever, operated with a knob. It was sold as a B&G product also.You can still find them around. Low Energy in Colorado shows them, also e-bay

The spring checks Caleffi sell now do not have the manual lever, same spring, .25 psi, 1-1/2 and larger is .50 psi.

The B&G iron FloChecks were .33 psi pop. I think they have been discontinued
