Energizing the proportional pilot valves VStA or VStB actuates the 4\/3 directional control valve. A double-acting attachment, such as shears (open\/close), is thus supplied via connections A and B. By energizing the proportional pilot valve VSt1, a flow rate regulated by an upstream pressure compensator is provided at connection H. This can be used for operating single-acting consumers, such as a hammer or a compactor. Both consumers can be limited in their maximum operating pressure by pressure relief valves that operate on the pressure cut-off principle. The upstream 2-way pressure compensators maintain a constant pressure difference. Thus, the consumers are supplied with the required flow rate independently of the load. The valve provides an internal LS signal for the pump.<\/p>\n<\/div>\n<\/div>\n\n<div class=\"gb-element-a8f64ca5\">\n<div class=\"gb-element-5473df5a\">\n<div class=\"gb-element-79ea1676\">\n<img loading=\"lazy\" decoding=\"async\" width=\"300\" height=\"180\" class=\"gb-media-fb976e24\" alt=\"\" src=\"https:\/\/wessel-hydraulik.de\/wp-content\/uploads\/2026\/05\/227.371.301.9-prop.Stromregelventil_20x12_150dpi_1181x709-300x180.jpg\" title=\"227.371.301.9-prop.FlowControlValve_20x12_150dpi_1181x709\" srcset=\"https:\/\/wessel-hydraulik.de\/wp-content\/uploads\/2026\/05\/227.371.301.9-prop.Stromregelventil_20x12_150dpi_1181x709-300x180.jpg 300w, https:\/\/wessel-hydraulik.de\/wp-content\/uploads\/2026\/05\/227.371.301.9-prop.Stromregelventil_20x12_150dpi_1181x709-1024x614.jpg 1024w, https:\/\/wessel-hydraulik.de\/wp-content\/uploads\/2026\/05\/227.371.301.9-prop.Stromregelventil_20x12_150dpi_1181x709-768x461.jpg 768w, https:\/\/wessel-hydraulik.de\/wp-content\/uploads\/2026\/05\/227.371.301.9-prop.Stromregelventil_20x12_150dpi_1181x709.jpg 1182w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/>\n<\/div>\n\n\n\n<div>\n<h2 class=\"gb-text gb-text-172030b3\"><strong>Features<\/strong><\/h2>\n\n\n\n<p class=\"gb-text\">&#8211; Suitable for one double-acting and one single-acting auxiliary consumer<br\/>&#8211; Electrically proportional control of the output flow rate<br\/>&#8211; Suitable for load-sensing systems<br\/>&#8211; Additional intermediate plate with external pilot supply for use in closed circuits<\/p>\n<\/div>\n<\/div>\n<\/div>\n\n<div class=\"gb-element-932e69aa\">\n<div class=\"gb-element-b3fd6cc1\">\n<h2 class=\"gb-text gb-text-60c2ab53\"><strong>Circuit Diagram<\/strong><\/h2>\n<\/div>\n\n\n\n<img loading=\"lazy\" decoding=\"async\" width=\"816\" height=\"500\" class=\"gb-media-ef214eb5\" alt=\"\" src=\"https:\/\/wessel-hydraulik.de\/wp-content\/uploads\/2026\/01\/Schaltschema-1.jpg\" title=\"Circuit Diagram-1\" srcset=\"https:\/\/wessel-hydraulik.de\/wp-content\/uploads\/2026\/01\/Schaltschema-1.jpg 816w, https:\/\/wessel-hydraulik.de\/wp-content\/uploads\/2026\/01\/Schaltschema-1-300x184.jpg 300w, https:\/\/wessel-hydraulik.de\/wp-content\/uploads\/2026\/01\/Schaltschema-1-768x471.jpg 768w\" sizes=\"auto, (max-width: 816px) 100vw, 816px\" \/>\n<\/div>\n\n<div class=\"gb-element-a627f053\">\n<h2 class=\"gb-text gb-text-1c1940b5\"><strong>Applications<\/strong><\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Double-acting consumers such as shears, grapples, or swivel buckets<\/li>\n\n\n\n<li>Single-acting consumers such as hydraulic hammers or mulchers<\/li>\n\n\n\n<li>Proportional control for hammers, shears, compactors, grapples.<\/li>\n<\/ul>\n<\/div>\n\n<div>\n<div class=\"gb-element-64bdb44f\">\n<section class=\"wh-contact\">\n  <div class=\"wh-contact__left\">\n    <h2>HOW CAN WE HELP YOU?<\/h2>\n  <\/div>\n\n  <div class=\"wh-contact__right\">\n    <div class=\"wh-contact__info\">\n              <div class=\"wh-contact__label\">Head of Sales &#8211; Field Sales &amp; Development<\/div>\n      \n      \n      <div class=\"wh-contact__name\">Dr.-Ing.
