This ensures optimum evaporation of the injection water even with high rangeabilities and protects the valve housing against direct contact with water.

Following the pressure reduction, the injection water is added to a perforated seat cage, where maximum turbulence ensures optimal evaporation conditions. The perforated seat cage also protects the valve housing against direct contact with injection water. The valve housing can optionally be equipped with a condensate drain connection.<\/p>\n<\/div>\n      <\/div>\n    <\/div>\n\n    <div class=\"column is-full-mobile is-half-tablet c-step__column\">\n      <h3 class=\"c-step__title c-step__title--mobile\">Mini cooler (type 595) <\/h3>\n\n      <div class=\"c-step__image\">\n\n                \n  <div class=\"c-img c-img--square\">\n    <div class=\"c-img__full u-lazy\" data-background-image=\"https:\/\/arca-valve.com\/wp-content\/uploads\/2021\/09\/595_Minikuehler_1631535150.png\" style=\"background-position: 55.84% 51.52%;\"><\/div>\n    <div class=\"c-img__placeholder\" style=\"background-image: url(https:\/\/arca-valve.com\/wp-content\/uploads\/2021\/09\/595_Minikuehler_1631535150-16x0-c-default.png)\"><\/div>\n  <\/div>\n\n      <\/div>\n    <\/div>\n\n  <\/div>\n<\/div>\n<\/div>\n\n      <\/div>\n\n    \n      <div class=\"column is-one-third\">\n\n        <div class=\"c-tease c-tease--step\">\n\n  <div class=\"c-tease__image\">\n\n        \n  <div class=\"c-img c-img--square\">\n    <div class=\"c-img__full u-lazy\" data-background-image=\"https:\/\/arca-valve.com\/wp-content\/uploads\/2021\/09\/557-L3_1631535040.png\" style=\"background-position: 50% 50%;\"><\/div>\n    <div class=\"c-img__placeholder\" style=\"background-image: url(https:\/\/arca-valve.com\/wp-content\/uploads\/2021\/09\/557-L3_1631535040-16x0-c-default.png)\"><\/div>\n  <\/div>\n\n  <\/div>\n\n  <div class=\"c-tease__title u-text-center\">\n    Angle design with stem injection (type 550\/570)\n  <\/div>\n\n  <a data-glightbox=\"description: .modal-310945658; type: content; height: auto; width: 1800px;\" data-gallery=\"12561543\" class=\"c-tease__link glightbox\"><\/a>\n\n<\/div>\n\n<div hidden style=\"display:none;\" class=\"glightbox-desc modal-310945658\">\n  <div class=\"c-step\">\n  <div class=\"columns is-multiline c-step__columns\">\n\n    <div class=\"column is-full-mobile is-half-tablet c-step__column\">\n      <div class=\"c-step__content\">\n        <h3 class=\"c-step__title\">Angle design with stem injection (type 550\/570)<\/h3>\n        <div class=\"c-step__description\"><p>These flow\/sound-optimized steam valves in an angle design are based on cast and forged angle housings with welded ends and can be expanded as required in the outlet and equipped with the desired connections.

In addition, the packing does not draw any foreign substances or dirt into the cooler. The design of the ball\/seat ring system and the hollow stem avoids fatigue fractures and leaks at the nozzle. A patented three-stage pressure reduction significantly reduces wear on the nozzle and prolongs the lifetime and service life of the valve.<\/p>\n<\/div>\n      <\/div>\n    <\/div>\n\n    <div class=\"column is-full-mobile is-half-tablet c-step__column\">\n      <h3 class=\"c-step__title c-step__title--mobile\">Desuperheater (type 3) <\/h3>\n\n      <div class=\"c-step__image\">\n\n                \n  <div class=\"c-img c-img--square\">\n    <div class=\"c-img__full u-lazy\" data-background-image=\"https:\/\/arca-valve.com\/wp-content\/uploads\/2021\/09\/Einspritzkuehler_1631535349.png\" style=\"background-position: 50% 50%;\"><\/div>\n    <div class=\"c-img__placeholder\" style=\"background-image: url(https:\/\/arca-valve.com\/wp-content\/uploads\/2021\/09\/Einspritzkuehler_1631535349-16x0-c-default.png)\"><\/div>\n  <\/div>\n\n      <\/div>\n    <\/div>\n\n  <\/div>\n<\/div>\n<\/div>\n\n      <\/div>\n\n    \n      <div class=\"column is-one-third\">\n\n        <div class=\"c-tease c-tease--step\">\n\n  <div class=\"c-tease__image\">\n\n        \n  <div class=\"c-img c-img--square\">\n    <div class=\"c-img__full u-lazy\" data-background-image=\"https:\/\/arca-valve.com\/wp-content\/uploads\/2021\/09\/DU-Ventil_Treibdampf_1631535218.png\" style=\"background-position: 57.16% 56.19%;\"><\/div>\n    <div class=\"c-img__placeholder\" style=\"background-image: url(https:\/\/arca-valve.com\/wp-content\/uploads\/2021\/09\/DU-Ventil_Treibdampf_1631535218-16x0-c-default.png)\"><\/div>\n  <\/div>\n\n  <\/div>\n\n  <div class=\"c-tease__title u-text-center\">\n    Globe design with two-phase nozzle\n  <\/div>\n\n  <a data-glightbox=\"description: .modal-1801657588; type: content; height: auto; width: 1800px;\" data-gallery=\"12561543\" class=\"c-tease__link glightbox\"><\/a>\n\n<\/div>\n\n<div hidden style=\"display:none;\" class=\"glightbox-desc modal-1801657588\">\n  <div class=\"c-step\">\n  <div class=\"columns is-multiline c-step__columns\">\n\n    <div class=\"column is-full-mobile is-half-tablet c-step__column\">\n      <div class=\"c-step__content\">\n        <h3 class=\"c-step__title\">Globe design with two-phase nozzle<\/h3>\n        <div class=\"c-step__description\"><p>Motive steam cooling is used in applications with valves in straight-way design and critical, demanding cooling.
