Engineered for silent operation. Check-All valves close quickly and smoothly to minimize hammer noise. Spring Loaded
Functions equally well in either vertical or horizontal position with proper spring selection. Designed with the spring upstream of the seat, strategically placing it outside any mixing and potentially aggressive solutions. Poppet
Designed to reduce maintenance costs, the Check-All design is simple, rugged and efficient. The seating surfaces are parallel to each other, thereby eliminating the excessive wear occurring in plug, cone, and ball seats.
