What is the difference between the CA14 and CA14S models?

The standard CA14 uses a Viton (synthetic rubber) valve cone suitable for temperatures up to 200°C. The CA14S features a stainless steel (AISI 440B) valve cone, allowing operation up to 250°C and better compatibility with aggressive gases.

Can the CA14 be installed in any orientation?

No. The CA14 must be installed with the float arm in a horizontal plane so that the float rises and falls vertically. The flow direction must match the arrow marked on the body.

What is the minimum differential pressure required for the CA14 to operate?

The CA14 requires a minimum differential pressure of 0.1 bar to function properly. Ensure your system maintains this pressure differential across the trap.

Are spare parts and maintenance kits available for the CA14?

Yes. Spirax Sarco offers maintenance kits and seal kits for both CA14 and CA14S variants. Kits include gaskets, valve components, and internal parts for on-site servicing.

Is material certification available for this product?

Yes, the CA14 is available with material certification to EN 10204 2.2. Certification requirements must be specified at the time of order placement.

Overview

The Spirax Sarco CA14 is a float-type automatic liquid drainer designed for air and gas systems in industrial applications. It efficiently removes condensate and other liquids from compressed air lines, gas pipelines, and process systems without manual intervention.

Constructed with an SG iron body and cover, the CA14 offers durability and corrosion resistance suitable for demanding plant environments. The unit features a float-operated mechanism that responds to liquid accumulation, opening the valve to discharge condensate while preventing gas loss. The design is fully maintainable, allowing on-site servicing without complete replacement.

Two variants are available: the standard CA14 with a Viton (synthetic rubber) valve cone for general service, and the CA14S with a stainless steel valve cone for higher temperature or more aggressive applications. Both versions comply with the Pressure Equipment Directive (PED) and are available with EN 10204 2.2 material certification upon request.
