Product description:
The new series of pneumatic film direct single-seat control valve with top guide structure, with multi-spring actuator. The utility model has the advantages of compact structure, light weight, sensitive action, S-shaped fluid passage, small pressure drop loss, large valve capacity, precise flow characteristics and convenient disassembly and assembly. Widely used in precise control of gas, liquid and other media, process parameters such as pressure, flow, temperature, liquid level at a given value. Especially suitable for small amount of leakage before and after the valve is not small pressure on the workplace.
This
series of products have a standard type, regulation cut off, bellows
sealed, jacket insulation and other varieties. Nominal product pressure
rating PN10,16,40,64; body diameter range DN20 ~ 200. For fluid
temperature from -200 ℃ ~ + 560 ℃ range of a variety of grades. Leakage
standards have grade IV or VI level. Flow characteristics are linear or
equal percentage. A wide variety of specifications to choose from.
Features:
1, top-oriented single-seat control valve, compact structure, fewer parts, easy maintenance.
2, the metal spool for a variety of workplaces, up to Level IV leakage
standards, ZXPQ-type soft-sealed spool up to Level VI leakage
standards.
3, the valve body designed by the principle of fluid mechanics, such
as cross-section low flow resistance flow channel, the rated flow
coefficient increased by 30%.
4, adjustable range, the inherent adjustable ratio of 50.
5, the implementing agencies using multi-spring structure, a 30% reduction in height, weight reduction of 30%.
6, ZXPV bellows sealed control valve, the valve stem to form a complete seal, blocking fluid leakage.
7, ZXPJ-type control valve with a thermal jacket for fluid cooling
easy to crystallize, clogging caused by solidification of the occasion.
