Nominal diameter DN15~100

Product Features

1. CAE structural strength analysis is used for the valve body flow channel and wall thickness, aiming to minimize weight and save costs while meeting the minimum wall thickness design requirements and design strength, resulting in high economic efficiency. 2. The valve body flow channel is S-shaped, with low pressure drop loss and high flow rate. 3. By utilizing pressure changes in the medium for regulation, the control accuracy is high.

Typical performance

ZZYP self operated pressure single seat regulating valve adopts an external pressure tapping structure, which can achieve automatic regulation and stable pressure by relying on the pressure changes of the medium itself. It is suitable for nominal diameter ≤ DN100, P1≤1.0MPa，P2≥15KPa， In situations where the pressure reduction ratio is ≤ 10, ≥ 1.25 for liquids, vapors, non corrosive gases, and low viscosity liquids.

This series is divided into two types: valve rear ZZYP-B and valve front ZZYP-K.
