Features
- 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).
- Guaranteed — Guaranteed against defects in materials or workmanship for 3 years.
- Improved Energy Savings — Maximum elimination of air and non-condensibles–trap closes at saturated steam temperature.
- Renewable In-line — With factory packaged, precision matched internal parts kits.
- Superior Performance — Fast response to changing pressure and condensate loads. Maximum air handling capability.
- Temperature Sensitive Actuator — One moving part stainless steel welded actuator for maximum corrosion, thermal and hydraulic shock resistance.

As condensate collects, it takes heat from liquid having a lower boiling point than water. thermal actuator, lowering internal pressure. Line On start-up, valve is normally open. When pressure will then compress thermal actuator to open steam enters trap, thermal actuator fill vaporizes valve and discharge condensate. Valve opening auto- to a pressure higher than line pressure. This matically adjusts to load conditions from minimum on forces valve into seat orifice to prevent any very light loads to full lift at maximum load. 845.778.5566 Fax: 845.778.1072 www.nicholsonsteamtrap.com 23 ACHIEVER “A” SERIES D B D THERMOSTATIC C A STEAM TRAPS B SPECIFICATION C A Steam trap shall be of balanced pressure design with stainless A AHV steel welded actuator capable of discharging condensate within 10°F of saturated temperature. Where greater sensitivity is required, SLR orifice and Sterilizer trim shall be available to allow condensate evacuation at or near saturated temperatures. Ther- Connections: 1/2" - 1" NPT mostatic actuator shall 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. Trap shall be bronze bodied suitable for pressures through 200 psig and available in 1/2" through 1" NPT connections. MAXIMUM OPERATING CONDITIONS PMO: Max.

HARD TO FIND A BETTER PROVIDER
Our company provides services to aid in the manufacture of technological products, such as semiconductors and flat panel displays, and often searching for distributors of obsolete product we require can waste time and money. Finding GID Industrial proved to be a great asset to our company, with cost effective solutions and superior knowledge on all of their materials, it’d be hard to find a better provider of obsolete or hard to find products.
Applied Materials
CONSISTENTLY DELIVERS QUALITY SOLUTIONS
Over the years, the equipment used in our company becomes discontinued, but they’re still of great use to us and our customers. Once these products are no longer available through the manufacturer, finding a reliable, quick supplier is a necessity, and luckily for us, GID Industrial has provided the most trustworthy, quality solutions to our obsolete component needs.

TERRIFIC RESOURCE
This company has been a terrific help to us (I work for Trican Well Service) in sourcing the Micron Ram Memory we needed for our Siemens computers. Great service! And great pricing! I know when the product is shipping and when it will arrive, all the way through the ordering process.

GO TO SOURCE
When I can't find an obsolete part, I first call GID and they'll come up with my parts every time. Great customer service and follow up as well. Scott emails me from time to time to touch base and see if we're having trouble finding something.....which is often with our 25 yr old equipment.
