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.


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.


Flange Insert Valve
Flange Insert Valves (F1, F6, FP) can be installed in any flanged connection in the system, horizontally or vertically, with no alterations to existing pipe necessary. Simply spread a flanged joint, insert the valve and tighten the bolts.
Sanitary Valves
Sanitary Cartridge Valve (SC) is a 316 stainless steel check valve for use in new or existing sanitary systems. The SC design seals on the ID of sanitary ferrules with replaceable food grade seals.
Union Insert Valve
The Union Insert Valve (UV) is designed to be inserted into most standard 45° ground joint unions. It provides the simplest and most economical way to install a check into a system.
Universal Valves
The Universal low (U3) (to 3,000 psig) and high (U1) (to 10,000 psig) pressure check valves have a single piece body construction machined from bar stock. These economical valves are designed for maximum flow and minimum pressure drop.
Flanged Valves
The Check-All Flanged & Drilled (HV) & the Check-All Flanged & Drilled Lined (HT) check valves are a one piece body with ANSI/ASME B16.5 Class 150 flanged ends.
Wafer Valve
The Wafer Valve (WV) has a "drop in" body style that fits inside the bolt circle for quick installation and removal in rigid piping applications. Many valves in this series meet API 594 requirements.
