Pre-cleaning Area

The cleanroom is surrounded by a chase area where pre-cleaning operations take place. Pre-cleaning operations are supported by clean, dry, oil-free air filtered to 1µm; a 5-ton bridge crane; a large heavy-duty parts washer; and reverse osmosis / deionized water system meeting D1193 specifications for reagent grade water.

Gowning and
Staging Area

Sliding entry doors accommodate loads on pallet jack up to 20-inch bore, ASME 600 class valve.

Cleaning and
Inspection Area

The heart of the cleanroom—includes areas for solvent wiping and degreasing, multiple-stage ultrasonic cleaning, point-of-use filtered drying, and cleanliness verification. This area is also fitted with a 2-ton cleanroom-compatible bridge crane.

Assembly, Test and Packaging Area

Features a stainless steel horizontal valve tester that has a clamping capacity up to 25 tons and accepts valve ID sizes from 3/4 to 10 inches. This area also has a 3-ton cleanroom-compatible bridge crane and a torque fixture. All gases used for testing are filtered at point of use.
