DC1221 Multi-stage anti-cavitation valve

DC1221 Multi-stage anti-cavitation valve Introduction

The DOCN high-pressure differential series regulating valve is a control valve specifically designed for harsh conditions such as high temperature and high pressure differential. Both compressible and incompressible fluids can ensure precise control and long lifespan, and can solve problems such as cavitation and noise. In addition, due to the high quality and performance of this series, maintenance costs are reduced and the system is simplified. At the same time, the design of process pipelines can be made more compact as there is no need for orifice plates or pipe silencers. Please select DC1834, DC1221, DC1844, and DC1854 based on fluid conditions.
