Yarway Series C-250 and C-260 Process Thermodynamic Steam Traps

Process Thermodynamic Steam Traps
Series C-250 and C-260

The Yarway High Pressure Integral Strainer Trap is designed with Quick Change Trim (QCT) using the proven variable orifice (piston) internals. These traps are designed for a variety of high pressure applications found in utility, industrial and marine service.

The small lightweight design and broad range of operating pressures are among the many advantages when compared to mechanical traps of the same pressure rating. In addition, the QCT design is renewable in-line with factory set and assembled internals.

Back Pressure Ratings:
Back pressure to 25% as factory set; (to 55% with removal of split washer, based on absolute pressure, C-250 only).

How to Specify and Order:
Typical Specification – the trap shall be Piston Valve, Quick Change Trim, Integral Strainer, Impulse Trap and shall require neither bucket, bellows nor bimetallic element for operation – (option ½" socketweld blow-off connection)

(1) Designate size of end connections
(2) Designate figure number
(3) Designate trap internals (capacities curve and selector guide)
(4) Designate “R” for commercial. Example: 1½" C-250ESWR.

Applicable Codes and Standards:
Pressure ratings per ANSI/FCI-69-1. Performance testing per ANSI/ASME PTC-39.1, FCI 69.1 and 85.1. End connections per ANSI B16.11.

How to Interpret the Curves:
For optimum service life limit the C-250 to 600 psi operation and the C-260 to 1500 psi operation. Traps will operate above recommended pressure (C-250 up to 1000 psi, C-260 up to 3000 psi). However, the service life may be reduced.

Typical applications include: fuel oil heaters, air heaters, reboilers, soot blower drains, steam separators, and shell and tube heat exchangers.
