The process of assigning HS codes is known as "HS Classification". All products can be classified in the HS by using the General Rules for the Interpretation of the Harmonized System ("GRI") that must be applied in strict order. HS codes can be determined by a variety of factors including a product's composition, its form and its function.
Later special-quality tubes had not base and function swapped but were assigned a 4-digit number, [3] such as ECC2000 or ED8000, the first digit of which again denoting the base: 1 – Miscellaneous 2 – 10-pin Decal base ( JEDEC E10-61)
This level contains 219 Commodity (Product) Classes and 55 Service Classes totaling 274 Classes. The 3-Digit Code is primarily used to generate periodic expenditure history by department for fiscal planning, budget execution, and accounting. 5-Digit Class-Item Code The 5-Digit class-item Code is an expanded version of the 3-Digit class Code ...

The downstream side is the pipe or open air where the PORV directs its exhaust. The outlet pipe is typically larger than the inlet. 2 in × 3 in (51 mm × 76 mm), 3 in × 4 in (76 mm × 102 mm), 4 in × 6 in (100 mm × 150 mm), 6 in × 8 in (150 mm × 200 mm), 8 in × 10 in (200 mm × 250 mm) are some common sizes.
A trunnion ball valve has additional mechanical anchoring of the ball at the top and the bottom, suitable for larger and higher pressure valves (generally above 3.9 in (10 cm) and 580 psi (40 bar)). A floating ball valve is one where the ball is not held in place by a trunnion.
Schematic 3 way ball valve: L-shaped ball right, T-shaped left. Valves with three ports serve many different functions. A few of the possibilities are listed here. Three-way ball valves come with T- or L-shaped fluid passageways inside the rotor. The T valve might be used to permit connection of one inlet to either or both outlets or connection ...
The electrohydraulic servo valve first appeared in World War II.The EHSVs in use during the 1940s were characterized by poor accuracy and slow response times due to the inability to rapidly convert electrical signals into hydraulic flows.
