TD42L / TD42H Thermodynamic Steam Trap Spirax Sarco
The TD42L was designed for small capacities, such as pipeline drainage. For process drainage, the TD42H type is available.
The TD42LA and TD42HA feature a self-venting disc for automatic venting at startup. These condensate valves are chemically nickel-plated (ENP), contributing to corrosion resistance and energy savings.
Standards
These products fully comply with the European Directive on Pressure Equipment 97/23/EC.
Certification
These products are available with a certificate according to the Type Test Report for an additional cost. Certificates are only included if explicitly requested when ordering.
