Therefore, efforts are being made to find sustainable solutions in hydraulics. One of these solutions is the use of water instead of hydraulic oil in hydraulics (power control hydraulics &#8211; PCH). However, since the use of water in water hydraulics (water PCH) is very little known to the public and only a few components for the successful use of water in water hydraulics (PCH) are available on the market, we have replicated an inadequately functioning two-stage safety valve for this purpose. The article describes the development, manufacture, numerical calculation and testing of a two-stage pressure relief valve designed for pressures up to 300 bar and flows up to 28 l\/min for the water PCH sector.<\/p>\n<p style=\"text-align: justify;\"><strong>Key words:<br \/><\/strong>two-stage pressure relief valve, water hydraulics, testing, development<\/p>\n<p>[\/et_pb_text][et_pb_button button_url=&#8221;https:\/\/revija-ventil.si\/wp-content\/uploads\/pugelj_01_2025.pdf&#8221; url_new_window=&#8221;on&#8221; button_text=&#8221;Download PDF&#8221; admin_label=&#8221;Gumb Prenesi PDF&#8221; _builder_version=&#8221;4.27.4&#8243; custom_button=&#8221;on&#8221; button_text_size=&#8221;15px&#8221; button_text_color=&#8221;#00868a&#8221; button_bg_color=&#8221;rgba(0,0,0,0)&#8221; button_border_color=&#8221;#00868a&#8221; button_icon=&#8221;&#xe0e8;||divi||400&#8243; custom_margin=&#8221;||0px||false|false&#8221; custom_margin_tablet=&#8221;||20px||false|false&#8221; custom_margin_phone=&#8221;&#8221; custom_margin_last_edited=&#8221;on|desktop&#8221; custom_padding=&#8221;||||false|false&#8221; locked=&#8221;off&#8221; global_colors_info=&#8221;{}&#8221; button_border_color__hover_enabled=&#8221;on|hover&#8221; button_border_color__hover=&#8221;#00868a&#8221;][\/et_pb_button][et_pb_post_nav in_same_term=&#8221;on&#8221; prev_text=&#8221;Older entries&#8221; next_text=&#8221;Newer entries&#8221; admin_label=&#8221;Navigacija po objavah&#8221; _builder_version=&#8221;4.3.3&#8243; custom_margin=&#8221;||||false|false&#8221; custom_margin_phone=&#8221;||||false|false&#8221; custom_margin_last_edited=&#8221;off|desktop&#8221; custom_padding=&#8221;20px||||false|false&#8221; custom_padding_tablet=&#8221;0px||0px||false|false&#8221; custom_padding_phone=&#8221;0px||0px||false|false&#8221; custom_padding_last_edited=&#8221;on|tablet&#8221; title_text_color_last_edited=&#8221;off|desktop&#8221; global_module=&#8221;11763&#8243; locked=&#8221;off&#8221; global_colors_info=&#8221;{}&#8221; title_text_color__hover_enabled=&#8221;on|desktop&#8221; title_text_color__hover=&#8221;#212b31&#8243;][\/et_pb_post_nav][\/et_pb_column][et_pb_column type=&#8221;1_4&#8243; _builder_version=&#8221;4.16&#8243; custom_padding=&#8221;|||&#8221; global_colors_info=&#8221;{}&#8221; custom_padding__hover=&#8221;|||&#8221;][et_pb_sidebar orientation=&#8221;right&#8221; area=&#8221;et_pb_widget_area_4&#8243; disabled_on=&#8221;on|on|off&#8221; _builder_version=&#8221;4.3.3&#8243; global_module=&#8221;11764&#8243; global_colors_info=&#8221;{}&#8221;][\/et_pb_sidebar][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Environmental policy has recently moved towards sustainable development in all areas.
