NICHOLSON STEAM TRAP ACHIEVER “A” SERIES THERMOSTATIC STEAM TRAPS Pressures To 200 PSIG (13.8 barg) Temperatures to 400°F (204°C) Actuator Construction — Internal guide rod and tube for Shown in AHV Configuration vibration resistance and positive valve to seat alignment. Improved Energy Savings— Maximum elimination of air and non-condensibles–trap closes at saturated steam temperature. Compact — Requires minimum space and provides condensate capacities equal to larger mechanical traps. Freeze Proof — Type A with horizontal inlet and vertical outlet. Type AHV when installed vertically (outlet down) or horizontally on side (cover perpendicular to ground). Renewable In-line — With factory packaged, precision matched internal parts kits. Superior Performance — Fast response to changing pressure and condensate loads. Maximum air handling Applications capability. Unit Heaters Air Vent —Efficient steam service air vent when equipped Sterilizers with ISO filled actuator and installed in air vent location. Air Vents Guaranteed — Guaranteed against defects in materials or Autoclaves workmanship for 3 Years.

See page 8 Options ST - Sterilizer Trim SLR - SLR Orifice HC - High capacity orifice Canadian Registration # 0E0591.9 Operating Principle Thermal actuator is filled at its free length with a liquid it takes heat from thermal actuator, lowering internal having a lower boiling point than water. On start-up, pressure. Line pressure will then compress thermal actuator valve is normally open. When steam enters trap, to open valve and discharge condensate. Valve opening thermal actuator fill vaporizes to a pressure higher automatically adjusts to load conditions from minimum on than line pressure. This forces valve into seat orifice very light loads to full lift at maximum load. to prevent any further flow.

Where greater sensitivity is required, SLR orifice and Sterilizer trim will be available to allow condensate evacuation at or near saturated temperatures. Thermostatic actuator shall Connections: 1/2" - 1" NPT employ a conical valve lapped in matched sets with the seat ring assuring tight shut off. A minimum of two orifice sizes shall be available allowing for custom capacity sizing. Materials of Construction Trap shall be bronze bodied suitable for pressures through Body & Cover: ASTM B283 C37700 200 psig and available in 1/2" through 1" NPT connections.
