Press Bronze Check Valve
The Viega 79055 is a 1-1/2 inch inline spring check valve built from low-lead bronze with press-to-press connections. It suits residential and commercial plumbing systems that need automatic backflow prevention in horizontal or vertical runs.
Capacity and headroom
A cracking pressure of .5 psi lets flow start with minimal head while the stainless-steel spring keeps the seal tight against reverse pressure. Rated for 200 psi at 200 °F water service, it handles typical hot-water loops but is not rated for steam applications.
Build integration
Press connections eliminate threading or soldering, so the valve fits directly into compatible copper or stainless press systems without extra fittings. EPDM seals tolerate temperatures from 0 °F to 200 °F, and the full-port design is not offered on this model, so flow capacity matches the reduced-bore spring mechanism.

Questions about this item
Will the 1-1/2" press ends connect to my existing copper piping without soldering?
Yes, the press x press connection type joins to compatible copper tubing using a press tool, eliminating the need for solder or flux.
How can I confirm the spring check valve is operating correctly after installation?
Flow water through the line; the valve should open at .5 psi cracking pressure and close tightly when flow stops, preventing backflow.
Does the box include the press tool or EPDM seals, or must I purchase them separately?
The valve ships with EPDM seals installed; a compatible press tool is not included and must be sourced separately.
