Угловые клапаны

Клапаны углового типа серии 350 (PN 16 – 250) и 380 (PN 16 – 400) являются частью хорошо зарекомендовавшей себя модульной системы ARCA. При сложных рабочих условиях и там, где важно учитывать уровень шума, часто рекомендуют использовать угловые клапаны, потому что поток среды, по сравнению с одно- или двухседельными клапанами, поворачивается на 90°только единожды.


  • Обычно оснащается хорошо зарекомендовавшим себя реверсивным мембранным приводом ARCA в оболочке.
  • Тип привода по выбору: пневматический, гидравлический, электрический или ручной.
  • Универсальность модульной системы ECOTROL® для внутренних деталей.
  • Заменяемая дроссельная система.
  • Различные исполнения шпинделя, например: с ребрами охлаждения, изолирующей колонной, сильфонным уплотнением и т.д. Легко взаимозаменяемы.
  • Использование различных материалов способствует адаптации к среде и перепадам давления.

Описание технологий

Three-way control valves

The ARCA three-way control valve is designed to be used as a three-way or mixing valve, depending on the applica-tion. As a three-way valve, the incoming medium is split into two individual flows. This split can be 1:1 or a different ratio can be used. As a mixing valve, two media are mixed in the valve housing and exit the three-way valve in the desired new state.

Double-seat control valves

The ARCA double-seat control valve is characterized by its simple and robust design, featuring a double guided trim, and is used for larger volumetric flows. The flow is con-trolled at two ports, whereby both plug diameters are coordinated such that the medium exerts an opening force on the one plug and a closing force on the other and the actuating forces almost compensate each other out as a result. The plugs can take a variety of shapes to meet appli-cation requirements.

Angle valves

The ARCA angle valve is used in very specific plant appli cations. The ARCA modular parts system therefore integrates housings made from different cast and forged materials so that a wide variety of requirements can be met. The internals, however, always follow the same basic clamped principle of the ECOTROL® series. The process fluid flows into the angle-control valve from the side or the bottom and exits after just one deflection.

Forged valves

ARCA forged valves are made from a forged block or a dye-forged housing. Defining characteristics is the large selection of housing materials and the resulting increase in structural safety. Forged control valves are especially used in conjunction with welded ends, since they can be con-nected directly to the piping here. The internals also follow the basic clamped principle of the ECOTROL® series.

Angle-control valve
The ARCA modular parts system includes a cast model as a basic version. This cast housing series meets the requirements of basic applications. The plug used is a single-step parabolic plug. Stem sealing can be realized with cooling fins or bellows in addi-tion to the standard bonnet, whereby the packing is selected based on the application.
Further options such as a heating jacket can be added.
Angle-control valve
ARCA not only offers angle-control valves in low-pressure design, but also ones rated to a nominal pressure of 250 bar (PN 250).
Several cast models are available for different materials and can withstand temperatures up to 600 °C. The base design integrates butt weld ends to allow the housings to be adapted for individual application require-ments. Different valve trims are available, all of which feature the proven clamped seat ring design. Bonnet seals include all common versions through to a self-sealing pinch cap from Brettschneider.
Angle-control valve
ARCA cast models cannot always serve all of your applications, which is why several forged housings have been designed around proven, standardized valve trims and bonnets.
Your specific material, pressure, and tem-perature requirements are met, thanks to a nominal pressure rating of more than 250 bar (PN 250) and a temperature range beyond 600 °C. Such performance allows ARCA to provide the optimal solution for all applica-tions involving angle-control valves.
