    The Equlibar QPV is a high resolution electronic pressure regulator providing\u00a0a regulated output pressure that is proportional to an electrical command signal input. The QPV1 is available in a wide range of calibrated pressure ranges covering vacuum through 150 psig \/10 bar(g). The QPV is available in either 0 -10 VDC or 4-20 mA analog signal types.<\/p>\n

    The QPV is a relatively low flow regulator, making it a great choice any time low flow rates or small volumes require precise pressure control. The QPV is often used to provide the pilot pressure signal to the dome of either an Equilibar\u00ae back pressure regulator or an Equilibar\u00ae vacuum regulator. The QPV can then be used to electronically control back pressure or vacuum pressure in line sizes from 1\/8 inch through 4 inch by pilot operating the appropriately sized regulator.\u00a0qpv \u662f\u4e00\u4e2a\u76f8\u5bf9\u8f83\u4f4e\u7684\u6d41\u91cf\u8c03\u8282\u5668, \u56e0\u6b64, \u6bcf\u5f53\u4f4e\u6d41\u91cf\u6216\u5c0f\u4f53\u79ef\u9700\u8981\u7cbe\u786e\u7684\u538b\u529b\u63a7\u5236\u65f6, \u5b83\u90fd\u662f\u4e00\u4e2a\u5f88\u597d\u7684\u9009\u62e9\u3002qpv \u901a\u5e38\u7528\u4e8e\u5411 equilibal\u00ae\u80cc\u538b\u8c03\u8282\u5668\u6216 equilibar\u00ae\u771f\u7a7a\u8c03\u8282\u5668\u7684\u5706\u9876\u63d0\u4f9b\u5bfc\u9891\u538b\u529b\u4fe1\u53f7\u3002\u7136\u540e, qpv \u53ef\u7528\u4e8e\u901a\u8fc7\u8bd5\u70b9\u64cd\u4f5c\u9002\u5f53\u5c3a\u5bf8\u7684\u8c03\u8282\u5668, \u4ee5\u7535\u5b50\u65b9\u5f0f\u63a7\u5236\u7ebf\u5c3a\u5bf8\u4e3a1.5 \u82f1\u5bf8\u81f34\u82f1\u5bf8\u7684\u80cc\u538b\u6216\u771f\u7a7a\u538b\u529b\u3002<\/p>\n
