O que significam as letras do válvula de redução de pressão para cilindros de gás W21.8-14RH(F)? Qual é a letra que representa a rosca externa?

Gases de metano em cilindros de 40 litros, como QF-30, QF-30A, etc. A rosca é do tipo W21.8-14LH(F). O diâmetro externo da rosca é de Ø21,8 mm. Há 14 dentes por polegada; o número 14 indica um passo de 1,8142 mm. LH indica basicamente a direção da rosca.
