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.
ZJHP Pneumatic Diaphragm With Hand Wheel Single-seat Regulating Valve 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.
