Dab tsi yog WCB / LCB / LCC / WC6 / WC hauv lub valve?
Wrought, casting;
C-Carbon hlau;
A, B, C qhia tau hais tias lub zog steel nqi ntawm qis mus rau siab
WCA, WCB, WCC txhais tau tias carbon steel, ABC txhais tau hais tias siv theem, feem ntau siv WCB.WCB cov khoom siv yeeb nkab yuav tsum yog A106B, cov khoom siv forging yog A105.
WC6 yog alloy steel castings, sib xws rau cov khoom siv yeeb nkab yog hais txog A355 P11, forging rau A182 F11;
Kuj tseem muaj WC9, qhov kub-resistant alloy steel, sib haum rau A355 P22, thiab cov forgings sib haum rau A182 F22.
WC weldable castings
LCB / LCC (ASTM A352) qis carbon steel
ITCS rau kev cuam tshuam toughness carbon steel; Impact Test C=Carbon S=Steel (A350)
Split body Split body, side entry (xws li tus actuator) Sib haum rau TOP nkag
Valve feem ntau siv carbon steel castings thiab forgings khoom rooj
