Figure 4.28a shows construction of a typical valve. This is similar in construction to a 3\/2 way pilot-operated valve, but the space above the main valve is comparatively large and pilot air is only allowed in via a flow&shy; reducing needle valve. There is thus a time delay between applica&shy;tion of pilot pressure to port Z and the valve operation, as shown by the timing diagram in Figure 4.28b. The time delay is adjusted by the needle valve setting. <\/p>\n<p align=\"justify\">The built-in check valve causes the reservoir space above the valve to vent quickly when pressure at Z is removed to give no delay off. <\/p>\n<p align=\"justify\">The valve shown in Figure 4.28 is a normally-closed delay-on valve. Many other time delay valves (delay-off, delay on\/off, nor&shy;mally-open) can be obtained. All use the basic principle of the air reservoir and needle valve. <\/p><div class=\"bmooy6a0dcc3b2c1bf\" ><script type=\"text\/javascript\">\n\tatOptions = {\n\t\t'key' : '0c1eb4c533eaedb7b996f49a5a4983a9',\n\t\t'format' : 'iframe',\n\t\t'height' : 300,\n\t\t'width' : 160,\n\t\t'params' : {}\n\t};\n<\/script>\n<script type=\"text\/javascript\" src=\"\/\/www.highperformanceformat.com\/0c1eb4c533eaedb7b996f49a5a4983a9\/invoke.js\"><\/script><\/div><style type=\"text\/css\">\r\n@media screen and (min-width: 1201px) {\r\n.bmooy6a0dcc3b2c1bf {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 993px) and (max-width: 1200px) {\r\n.bmooy6a0dcc3b2c1bf {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 769px) and (max-width: 992px) {\r\n.bmooy6a0dcc3b2c1bf {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 768px) and (max-width: 768px) {\r\n.bmooy6a0dcc3b2c1bf {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (max-width: 767px) {\r\n.bmooy6a0dcc3b2c1bf {\r\ndisplay: block;\r\n}\r\n}\r\n<\/style>\r\n<div class=\"dqcow6a0dcc3b2c06c\" ><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-0778475562755157\"\n     crossorigin=\"anonymous\"><\/script>\n<!-- 300x600 hydraulics-and-pneumatics -->\n<ins class=\"adsbygoogle\"\n     style=\"display:inline-block;width:300px;height:600px\"\n     data-ad-client=\"ca-pub-0778475562755157\"\n     data-ad-slot=\"3735577695\"><\/ins>\n<script>\n     (adsbygoogle = window.adsbygoogle || []).push({});\n<\/script><\/div><style type=\"text\/css\">\r\n@media screen and (min-width: 1201px) {\r\n.dqcow6a0dcc3b2c06c {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 993px) and (max-width: 1200px) {\r\n.dqcow6a0dcc3b2c06c {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 769px) and (max-width: 992px) {\r\n.dqcow6a0dcc3b2c06c {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (min-width: 768px) and (max-width: 768px) {\r\n.dqcow6a0dcc3b2c06c {\r\ndisplay: block;\r\n}\r\n}\r\n@media screen and (max-width: 767px) {\r\n.dqcow6a0dcc3b2c06c {\r\ndisplay: block;\r\n}\r\n}\r\n<\/style>\r\n\n<p align=\"justify\">The symbol of a normally-dosed time delay valve is shown in Figure 4.28c. <\/p>\n<p align=\"justify\"><a href=\"http:\/\/lh3.googleusercontent.com\/-eIE6VzSTQVs\/VcDbNUb4TXI\/AAAAAAABzQU\/6zOflszqE2E\/s1600-h\/Control%252520valves-0110%25255B2%25255D.jpg\"><img decoding=\"async\" loading=\"lazy\" style=\"background-image: none; border-bottom: 0px; border-left: 0px; margin: 0px auto; padding-left: 0px; padding-right: 0px; display: block; float: none; border-top: 0px; border-right: 0px; padding-top: 0px\" title=\"Control valves-0110\" border=\"0\" alt=\"Control valves-0110\" src=\"http:\/\/lh3.googleusercontent.com\/-YWf4K48kb5U\/VcDbUP0RS9I\/AAAAAAABzQg\/WdNF76Ceyv0\/Control%252520valves-0110_thumb.jpg?imgmax=800\" width=\"244\" height=\"239\" \/><\/a> <\/p>\n<p align=\"justify\">\n<p align=\"justify\">\n<p align=\"justify\"><\/p>\n","protected":false},"excerpt":{"rendered":"<p>lime delay valves Pneumatic time delay valves (Figure 4.28) are used to delay opera&shy;tions where time-based sequences are required.
