Válvula Controladora de Pressão RP 820

Descrição

Self-acting back pressure regulators are simple control valves offering accurate control while being easy to install and maintain. They control the pressure upstream of the valve without requiring pneumatic or electrical control elements. The RP 820 overflow valve is a pilot-controlled control valve consisting of a main valve, a pilot valve complete with restrictor assembly and built-in strainer mounted on the cover of the main valve, non-return valve and restrictor valves. The valve cone can be fitted with a soft or metallic seal. Quando a pressão de entrada atinge a pressão definida, a válvula piloto restringe o fluxo. Essa descrição é longa e técnica, mas contém as informações necessárias para o usuário entender o funcionamento da válvula.
