The Spence B Series Steam trap is of balanced pressure design with stainless steel welded actuator capable of discharging condensate within 10°F of saturated temperature. Where greater sensitivity is required or protection from flash steam locking, a SLR orifice will be available to allow condensate and flash steam evacuation at or near saturated temperatures. Thermostatic actuator employs a conical valve lapped in matched sets with the seat ring assuring tight shut off. Trap is cast iron or cast steel bodied suitable for pressures to 250 psig and available in 1/2″ through 2″ NPT.
