一、法蘭全啟式安全閥參數：
| 產品名稱： | 全啟式安全閥 |
| 產品型號： | A42Y、A44Y、A48Y |
| 產品口徑： | DN32~200 |
| 產品壓力： | 0.6~32.0Mpa |
| 產品材質： | 鑄鋼、不銹鋼、合金鋼等 |
二、法蘭全啟式安全閥概述：
安全閥的主要參數是排量，這個排量決定于閥座的口徑和閥瓣的開啟高度，由開啟高度不同，又分為微啟式和全啟式兩種。微啟式是指閥瓣的開啟高度為閥座喉徑的1/40～l/20。全啟式是指閥瓣的開啟高度為閥座喉徑的1/4。全啟式安全閥：應用在蒸汽介質是一般有一個突然全開動作，此突開動作時的壓力為整定壓力（突跳壓力）；應用在空氣介質是，先打開與進口壓力增加開高呈比例升高，然后再突然起跳全開，稱二段式開啟；一般不可用于液體介質。微啟式安全閥：先打開與進口壓力增加開高呈比例升高，壓力下降時亦隨進口壓力下降開高呈比例下降，一般用于液體介質（或保護管道時用于可壓縮氣體）。
