1. Dimensions and weights are for reference only. When required, request certified drawings.

2. Face to face values have a tolerance of ±0.06 in (±2.0 mm) for sizes 10" and lower and a tolerance of ±0.12 in (±3.0 mm) for sizes 12" and larger. 3. Cracking pressure is for horizontal installations only. For vertical installations, please consult factory. 4. Minimum Bore Diameter indicates the minimum internal diameter of the adjacent pipe.

Additional Design & Technical Notes:

• The CV42L has a fugitive emission design. The retainer design body design 

eliminates potential leak paths to the environment so there are no body emissions.

1. Dimensions and weights are for reference only. When required, request certified drawings.

2. Face to face values have a tolerance of ±0.06 in (±2.0 mm) for sizes 10" and lower and a tolerance of ±0.12 in (±3.0 mm) for sizes 12" and larger.

3. Cracking pressure is for horizontal installations only. For vertical installations, please consult factory.

4. Minimum Bore Diameter indicates the minimum internal diameter of the adjacent pipe.

Additional Design & Technical Notes:

• The CV 44 has a fugitive emission design. This retainer-less body design 

eliminates potential leak paths to the environment so there are no body emissions.

Illustrations are representative 

of sizes 8" through 24". Sizes 

2" through 6" are scalloped for 

dual pressure service (ANSI Class 

150 and 300). Please request

Additional Design & Technical Notes:

• The CV42 has a fugitive emission design. The innovative retainer design eliminates 

potential leak paths to the environment so there are no body emissions.

1. The listed pressure and temperature ratings for the valve's body, seat, and body seal 

are theoretical and may vary during actual operating conditions.

Additional Design & Technical Notes:

Short pattern check valves feature a reduced port and eccentric opening which 

allow the disc to open into the connecting pipe. However, given the short faceto-face, the disc will not fully open due to interference with the connecting pipe. 

Although this conforms to API specifications, this may be unsuitable for certain 

types applications. Consult factory for more specific application information.

1. Dimensions, weights, and flow coefficients are provided for reference only. When required, always request certified drawings.

2. Face to face values have a tolerance of ±0.06 in (±2.0 mm) for sizes 10" and smaller and a tolerance of ±0.12 in (±3.0 mm) for sizes 12" and larger.

2. Cracking pressure is for horizontal installations only. For vertical installations, please consult factory. Valve can not be installed in the vertical position with downward flow.

are theoretical and may vary during actual operating conditions.

Additional Design & Technical Notes:

Short pattern check valves feature a reduced port and eccentric opening which 

allow the disc to open into the connecting pipe. However, given the short faceto-face, the disc will not fully open due to interference with the connecting pipe. 

Although this conforms to API specifications, this may be unsuitable for certain 

types applications. Consult factory for more specific application information.
