Cage guided globe control valve use separate sleeve, large guide structure, balance pressure sealing ring, high-performance nonmetal sealing ring, has a good dynamic stability, high control precision, allow the pressure difference is big, the operating force is small, large flow capacity, etc. Suitable working condition of normal temperature, differential pressure, under the action of alternating stress control.
Product Description
Sleeve-guided control valve is a sleeve-guided, pressure-balanced single-seat control valve. It is TÜV ISO 15848 certified in 2019. It has a split sleeve construction and a high performance balanced seal ring seal. Suitable for fluid control in ambient and priming conditions. Bellows seal type is available. Thousands of applications in the fine chemical, petrochemical, pharmaceutical and other industries.
Performance advantages
Modular design concept, combining the American and Japanese schools of high-precision control and the German school of modular concept.
The inner cavity of the valve body is S-shaped distribution, smooth and without dead ends; there are guide wings inside the valve body, which can reduce the mutual force of the medium inside the valve body and reduce the occurrence of cavitation.
The use of sleeve guidance, large guide diameter, smooth guidance, with good dynamic stability.
The valve seat adopts floating design, while the sealing surface adopts tapered form to ensure good alignment of the sealing sub.
Sleeve window control flow characteristics, flow characteristics control accurately.
The structure of the inner part is balanced, allowing a large differential pressure, small operating force and large flow capacity.
Equipercent, linear and quick-open flow characteristics are available.
Good use in the temperature range of -80 to 593℃.
And pipeline connection with RF, RJ, FM and other flange type and SW, BW welding type.
The flange distance conforms to GB/T 17213.3-2005 / IEC 60534-3-1:2000; or ISA S75.03-1992 standard.
