Within the valve cavity 24 is a pressure operated closure member 33, here shown as a diaphragm which may be made of aluminum or different appropriate materials, with a heart portion 34 biased towards valve closing place as proven in FIG. 6 and a peripheral portion 35 clamped between the higher and https://www.complex-trade.ru/catalog/kholodilnoe/kamery/ lower valve elements 36 and 37 and retained there by the securing bolts 38 and 41. In a single embodiment of such a diaphragm utilizing liquid carbon dioxide because the liquid cryogen the peripheral portion 35 was 0.062 inch thick aluminum and was 0.006 inch greater at the center 34. This increased heart 34 as shown in stable lines in FIG. 6 biased the diaphragm toward closed position.
