Armstrong’s SH-4000 Bimetallic Steam Trap is the ideal design for applications involving superheated steam.
During start-up, the bimetallic mechanism is fully open and allows
large volumes of non-condensable gases and condensate to be removed from
the system. As the system reaches saturated steam conditions, the
mechanism begins to close preventing anylive steam loss. The superheat
during normal operating steam conditions keep the valve closed to ensure
long service life.
In the event that operating conditions change and condensate forms at
the steam trap inlet, the cooling effect allows the bimetallic
mechanism to open and discharge any accumulation. The valve quickly
closes once normal operating conditions return.
The SH-4000 consists of an investment cast, stainless steel body that
is compact and highly resistant to harsh, corrosive environments. The
integral mounting flange is compatible with the Armstrong IS-4, 4-bolt,
Class 900, connector making for labor savings and easy steam trap
