The Bushing Valve is a check valve with a standard bushing housing. The valve is adaptable to many types of service applications. It has very little restriction and produces a low pressure drop. It can be used quite effectively in systems where flow and pressure drop are critical by the use of a reducer coupling. The Bushing Valve also makes an excellent vacuum breaker. The high flow rate insures maximum effectiveness for vacuum breaker service. By reversing the direction of flow it can also be used as a low pressure relief valve.

The CAV series of valves are not catalog items but rather are custom designed and tailored to meet customer specific connections or valve configurations. If you have a check valve application where our standard catalog items do not quite match what you are looking for, contact our sales department to discuss your specific needs.

The EPIC™ Female Pipe valve is a poppet style check valve with female NPT threaded connections machined from 300 series stainless steel bar stock with Aflas® seat/seals and a 1/2-PSI stainless steel spring (cracking pressure) that can be installed in any flow orientation. This check valve achieves a high flow capacity and reduced pressure loss compared to other poppet style check valves of similar sized connections. Additionally, the EPIC™ series incorporates a replaceable drop-in check mechanism (EPIC™ Replaceable Insert Kit sold separately) that is easily installed into the existing body without requiring additional assembly of separate checking components.
Due to the materials of construction, high flow capacity, complete repairability and the quality customers have come to expect from Check-All, the EPIC™ check valves are uniquely suited for a very wide range of applications in liquids, gases and steam.

The EPIC™ Flared Tube valve is a poppet style check valve with 37° flared tube connections. These connections are integral to the body and meet SAE J514 & ISO 8434-2 dimensional standards. The check valves are machined from 300 series stainless steel bar stock with Aflas® seat/seals and a 1/2-PSI stainless steel spring (cracking pressure) that can be installed in any flow orientation. Additionally, the EPIC™ incorporates a replacable drop-in check mechanism (EPIC™ Replaceable Insert Kit sold separately) that is easily installed into the existing body without requiring additional assembly of checking components.
Due to the materials of construction, field rapairability, and the quality customers have come to expect from Check-All, the EPIC™ check valves are uniquely suited for a very wide range of applications in liquids, gases and steam.

The EPIC™ Male Pipe valve is a poppet style check valve with male NPT threaded connections machined from 300 series stainless steel bar stock with Aflas® seat/seals and a 1/2-PSI stainless steel spring (cracking pressure) that can be installed in any flow orientation.

Flange Insert valves are the ultimate check valves in flanged systems. They provide the simplest most economical way to install check valves in a piping system, the valve body automatically positions the valve and holds it in place while bolts are being installed and tightened. All that is required is two gaskets in place of the one normally used in a flanged joint. See additional installation guidelines or consult the factory for more information.

Flange Insert valves are designed to fit between two mating ANSI flanges. The “Spring Housing” designated by the “A” dimension is designed to be inserted into the upstream pipe, thereby centering it in the pipe. Therefore, there must be clearance between the spring housing and the pipe or flange. Generally speaking, the FIV Class 150 and 300 valves (F1) are designed for standard schedule pipe or Class 150 or 300 flanges, and the FIV Class 600 (F6) valves are designed for schedule 80 pipe or Class 600 flanges.

Flange Insert valves can be used as check valves, low pressure relief valves, and vacuum breakers by simply using different spring settings.

Generally speaking, the FIV Class 150 and 300 valves (F1) are designed for standard schedule pipe or Class 150 or 300 flanges, and the FIV Class 600 (F6) valves are designed for schedule 80 pipe or Class 600 flanges.

Flange Insert valves can be used as check valves, low pressure relief valves, and vacuum breakers by simply using different spring settings.

Flange Insert valves are the ultimate check valves in flanged systems. They provide the simplest most economical way to install check valves in a piping system, the valve body automatically positions the valve and holds it in place while bolts are being installed and tightened. All that is required is two gaskets in place of the one normally used in a flanged joint. See additional installation guidelines or consult the factory for more information.

Flange Insert valves are designed to fit between two mating ANSI flanges.
