Description

The CA14 is a range of float type automatic liquid drainers for air

and gas systems. The body and cover are of SG iron and the

complete unit is readily maintainable. The cover will be drilled

and tapped 1⁄2" BSP or NPT for the purpose of fitting a balance

line. The standard version with a Viton valve cone is designated

CA14 (DN15 and DN20 only). A stainless steel valve cone

version is designated CA14S. Both are available with horizontal

flanged connections with flow from right to left CA14 (R-L) or

from left to right CA14 (L-R).

Standards

The product fully complies with the requirements of the European

Pressure Equipment Directive 97/23/EC.

The product is available with a manufacturer's Typical Test Report.

Note: All certification/inspection requirements must be stated at

the time of order placement.

Sizes and pipe connections

DN15, DN20 and DN25.

Flanged EN 1092 PN16, ASME 150 and JIS/KS 10K.
