The Spence N450 steam trap is a mechanical valve which discharges condensate, undesirable air and non-condensibles from a system while trapping or holding in, steam. Thermostatic steam traps operate in direct response to the temperature within the trap. N450 Series steam trap is a balanced pressure design with stainless steel welded actuator capable of discharging condensate within 10°F / -12°C of saturated temperature. For greater sensitivity, SLR orifice and sterilizer trim are available to allow condensate evacuation at or near saturated temperatures. If subcooling of condensate is desired, alternate thermostatic actuator is available to allow condensate evacuation at or near 40°F/ 4.4°C below saturated temperatures. Thermostatic actuator has a conical valve lapped in matched sets with the seat ring assuring tight shut off. A minimum of three orifice sizes is available allowing for custom capacity sizing. Trap is forged carbon steel-bodied suitable for pressures through 450 psig / 31 bar and available in NPS 1/2 and 3/4 / DN 15 and 20 in NPT end connection.
