The standard operating pressure is 150 MPa, with a maximum allowable working pressure of 160 MPa.<br \/>\nThe required preload is set through the pressure regulating valve of a dedicated high-pressure hydraulic pump. The tensioners can be used for both tightening and loosening nuts.<br \/>\nHigh-pressure hoses are connected through quick couplers for convenient setup and operation. The tensioners feature a lightweight construction, simple structure, and easy maintenance.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Product Features Tensioning force range: 200\u20135,830 kN S [&hellip;]<\/p>\n","protected":false},"featured_media":548,"comment_status":"open","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[17],"product_tag":[],"class_list":["post-1188","product","type-product","status-publish","has-post-thumbnail","product_cat-hydraulic-bolt-tensioners","first","instock","shipping-taxable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/haojubolt.com\/index.php\/wp-json\/wp\/v2\/product\/1188","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/haojubolt.com\/index.php\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/haojubolt.com\/index.php\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/haojubolt.com\/index.php\/wp-json\/wp\/v2\/comments?post=1188"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/haojubolt.com\/index.php\/wp-json\/wp\/v2\/media\/548"}],"wp:attachment":[{"href":"https:\/\/haojubolt.com\/index.php\/wp-json\/wp\/v2\/media?parent=1188"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/haojubolt.com\/index.php\/wp-json\/wp\/v2\/product_brand?post=1188"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/haojubolt.com\/index.php\/wp-json\/wp\/v2\/product_cat?post=1188"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/haojubolt.com\/index.php\/wp-json\/wp\/v2\/product_tag?post=1188"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
